Category Archives: Fuel System
Hi Boise auto owners. Let’s talk fuel injectors. A fuel injector is a valve that delivers fuel to a vehicle’s engine. It has to deliver the precise amount of fuel, to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.
Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.
The pressure in a fuel injection system varies depending on its type. Many gasoline sedan engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.
Vehicles have one fuel injector for each cylinder in the engine. Your vehicle’s control computer constantly monitors the engine and various sensors in the vehicle and adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle’s engine. Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment to their performance. When an injector gets gummed up, it affects the pressure, pattern and timing of the fuel delivery. The result is a decrease in fuel efficiency and loss of engine performance for Boise auto owners.
So it’s to Boise car owners’ advantage to keep their fuel injectors clean. That starts with keeping the fuel in your tank clean. High-quality fuel contains detergents and additives that help clean your engine. Brand-name fuel companies also deliver a more consistent quality of fuel to Boise motorists than do bargain Boise area service stations.
The second way to keep your injectors clean is to keep your fuel filter clean. This filter screens dirt and rust out of the fuel as it travels from the tank to the engine. If the filter clogs up, fuel will bypass it and carry its load of dirt into the engine.
Boise motorists should check their owner’s manual to find out how often they should change their fuel filter. This should be part of your regular preventive maintenance. Also, remember that if you use bargain-brand or low-grade fuels, or if you drive an older vehicle between Boise, Boise and Garden City , your filter will need to be changed more often.
You can also purchase cleaners at Napa AutoCare Boise that will protect your fuel injectors. These cleaners are added to the fuel tank. They work best at preventing build-up in your fuel injectors and can clean up small amounts of carbon, gum and varnish. But they won’t be able to clean a fully gummed-up injector. Read the labels before using any of these products for full directions on their use. If your fuel injectors are gummed up, you can get a professional deep cleaning service at Napa AutoCare Boise in Boise that will result in better fuel economy and improved vehicle performance.
Good car care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.
The team at Napa AutoCare Boise in Boise and Idaho car owners are all talking fuel economy right now. Better gas mileage. Fewer emissions. Boise drivers want to save the environment and their pocketbooks.
And we all know—or should know—that preventive maintenance will help maximize fuel efficiency. But is there something more Boise motorists can do? After all, some of us Boise folks can’t cut back on our driving, and others would like to do more to economize.
Weight is one major enemy of fuel economy. The more you lug around in your vehicle, the more fuel you have to burn to get from Boise to Boise. And that means buying more gas in Boise and producing more emissions.
Of course, your sedan’s weight isn’t negotiable. And you can’t do much about the weight of your passengers. And this isn’t an article about diet and exercise.
But look around your sedan. Are you hauling a bunch of unnecessary weight around Idaho? Do you really need your golf clubs every time you leave your Boise home? Store sports equipment in the garage. Load it when you need it and store it when you don’t. Who knows? The extra exercise just might reduce the other type of weight in your vehicle.
The same goes for anything else in your car: make-up kits, music collections, extra electronics, spare clothing; whatever your particular extras may be. Pack it when you need it; store it when you don’t.
Clean out your Boise. You’d be surprised how much weight you’re lugging around Boise in plain old junk. Toss old papers, leftover food, and regular old dirt. Even if it’s not a lot of weight, you’ll feel better when you get into your car. A good cleaning is also part of good car care.
Now, don’t toss stuff you really do need. You do need that spare tire—the one in your trunk. And a kit of emergency essentials is not a bad idea. But just carry around the day-to-day essentials. You can pack a more extensive kit and store it in your garage, then toss it in your Boise when you go on a longer trip, but you don’t have to lug it around all the time. After all, are you a driver? Or are you a junk chauffeur?
Lose the junk and save some money in Boise.
All modern Boise vehicles come with fuel injection systems, so it’s a topic Boise car owners need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount, at the right time; to be mixed with air and burned in the engine.
So how many fuel injectors does your car have? There’s one for each cylinder. So four, six or eight for most folks in Boise, Idaho. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty high-tech.
Napa AutoCare Boise can help Boise car owners with a fuel injector cleaning service. What’s the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It’s critical that the fuel is sprayed in a particular pattern as determined by the engine design.
Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn’t get burned as efficiently as it could. That robs performance and hurts fuel efficiency.
What about dirty fuel – how does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high quality fuel. It’s tempting to shop for bargains in Boise with fuel prices as high as they are, but major brands in the Boise, Idaho area have better detergents and additives and deliver consistent quality.
What about a good fuel filter? The fuel filter is a critical component of the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it’s clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.
It’s important to replace the fuel filter when your auto maker recommends it. That’s part of a comprehensive fuel system cleaning.
There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines Boise auto owners are starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There’s no room for dirt and gum in a precision part like that.
There are a lot of good products available in Boise, Idaho that can clean fuel injectors. They’re best used by Boise auto owners to prevent fouling in the fuel injectors. Many can’t clean a seriously gummed up injector – that requires a professional deep cleaning, like those we offer at Napa AutoCare Boise in Boise. But putting the cleaner in the fuel tank after you’ve had Napa AutoCare Boise take a look at your fuel system will help keep it clean. Be sure to read the label for directions.
Give us a call if you think your sedan may be ready for a fuel injector cleaning.

Diesel engines have been used extensively in Europe and Asia for many years. They haven’t been as common in Boise because of the high sulfur content in our diesel fuel. But the government is now mandating lower sulfur content and, as a result, we are going to see more Boise drivers driving diesel-fueled vehicles on the road, especially in passenger cars and SUV’s.
Diesels are popular in Boise because they get better fuel efficiency than gas-powered engines. They also last longer. Modern diesel engines are quiet and powerful. And if you associate diesel engines with black smoke, then you’re not up with the times. That smoke is a thing of the past.
Diesels don’t produce any more pollutants than gasoline engines. The pollution standards for diesel-powered vehicles are as strict in Idaho as for other vehicles.
Also, diesel engines can run on bio-diesel fuels as well as fossil fuels. Diesel fuel can be produced from vegetable oil or from cellulosic waste like wood chips and sawdust. In Boise, we may soon see bio-diesel produced from algae. These fuel sources will lessen Boise drivers’ dependence on fossil fuels and may even become truly renewable and sustainable.
Diesel-powered vehicles perform as well as other passenger vehicles, also. Most Meridian people don’t notice a difference in driving one or the other. If you haul heavy loads or tow a trailer in Garden City, however, the diesel is a definite improvement.
So, you may be asking, if diesels are so great, why don’t all Boise motorists drive them? Surely there are disadvantages you haven’t told me about. That’s true. Diesel engines are heavier than gas engines, and they cost more in Idaho. The better fuel economy of the diesel engine is partially offset by the higher purchase price.
Because of higher fuel prices, diesel engines used to be more costly to drive in Boise. But now, with higher volatility in the prices of both gasoline and diesel fuel in Idaho, that cost difference is less definitive. Whether a diesel or gas engine is more expensive for Boise motorists depends now on the current price of fuel in Idaho and how many miles you drive.
Consider also that diesel-powered vehicles have a high resale value in the Boise area, and the costs of owning and operating a diesel vs. a gas-powered vehicle in Idaho becomes a real toss-up.
Preventive auto maintenance for diesel vehicles has also become similar to that of gas-fueled vehicles in recent years. The major difference is that diesels require cleaner fuel, air and oil, so their filters are more expensive in Boise than those for gasoline engines. The engine air filter must be changed more frequently as well.
The costs for car care and repairs in Boise are similar. Wait, you may be thinking, but you just told me that filters are more expensive and have to be changed more regularly. True, but that is offset by the fact that diesel engines have a much longer lifetime than gasoline engines. So if you are the type of owner who prefers to hang on to a vehicle for a long time, you will be more than rewarded with a diesel engine.
So if you have been looking for Napa AutoCare Boise auto advice on whether to switch to a diesel vehicle or stay with a gas-powered one, then we hope this helps. The answer as to which type of vehicle is better is that it depends on the Boise driver and their driving habits. Now that you know the facts, you can make an informed choice based on your own priorities and needs.
The price of gas in Idaho has got Boise drivers talking. It seems that Boise folks who need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially. That is why we thought it would be good to review some things that anyone can do to improve fuel efficiency.
First let’s start with how we drive in the Boise area. Boise auto owners may not realize that they can really save income on gas by just changing a few driving habits. One of the biggest is jackrabbit starts – you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don’t drive with one foot on the brake. That’s also a drag on fuel efficiency, and it wears out your brakes faster too.
Another thing Boise car owners can do is drive slower – but only when it’s safe. Sometimes on the interstate we drive an extra five … ten . . . twenty … over the speed limit. We do it to save time, but it only saves a few minutes out of maybe an hour long drive, and we may use 10 to 15 % more gas. Just leave Boise a little bit earlier, save some income and arrive more relaxed.
Boise car owners can also try and combine all of their errands for the day into just one trip, rather than several. If you can put off a trip today that can be combined with one tomorrow – you can save some time and cash.
Using your cruise control can save bucks too. Driving in Boise at a constant speed really improves fuel economy. Be sure to only use your cruise control in Idaho under safe conditions – you can look in your owner’s manual for some critical good tips on using your cruise control.
Did you know that reducing the weight in your sedan saves gas? Clean out the trunk or back seat from time to time so that you are not paying to carry around a lot of stuff around Boise you do not need in the car. If you live in Idaho where there is snow and ice, clear it off your car. They add weight and mess with aerodynamics too.
Another tip is to avoid long idle times, which includes warming it up when you start. Modern engines do not require a long warm up to get going – just take it easy for a couple of miles.
Be sure to get a new gas cap if yours leaks or is worn.
Now, let’s start talking mechanical. Bottom line – the better you maintain your vehicle, the less fuel you will use. It all adds up in a big way. For example, replacing your dirty engine air filter will pay for itself in improved gas mileage before your next oil change – and will keep saving you income after that.
A clean, well-maintained fuel system really pays big dividends in fuel efficiency for Boise motorists. A clogged fuel filter wastes gas. So does a dirty fuel system, grimy fuel injectors and plugged up PCV valves. A fuel system service decreases the gas you use, and increases the power – so Boise drivers can’t go wrong with that.
Some of us Boise auto owners ignore our Check Engine light. But fixing the problem that caused the light to come on will usually save some fuel as well. It may be a bad oxygen sensor that can really rob your fuel economy.
And, it may be time for a tune-up. Tune-ups should improve your fuel economy. Don’t overlook the essential routine maintenance items, like scheduled oil changes, transmission and cooling system service. Dirty or low fluids actually use more fuel. Just look at your auto maker’a recommended service intervals in the owner’s manual, or ask your Napa AutoCare Boise service advisor for the schedule.
Don’t forget your tires. Under-inflated tires waste gas. And if your wheels are out of alignment you won’t get the MPG you need.
None of these things are very complicated or expensive for Boise auto owners to stay on top of. When you maintain your car properly, you save gas today, and prevent costly repairs tomorrow.
Is your car sometimes hard to start on an early Boise morning? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your car’s fuel system starts with the air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy.
Most Boise auto owners have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner’s manual has a schedule for cleaning your fuel injectors and other essential parts of your fuel system.
Some Boise drivers are interested in buying fuel system cleaners that they can pour into your gas tank. You can do that – and there are lots of great products available that can help maintain an already clean fuel system – but these products cannot do a major cleaning. For that, you need to see Napa AutoCare Boise. Napa AutoCare Boise has the professional tools and chemicals to really do a complete service.
Napa AutoCare Boise uses a process that gives your car a deep, professional fuel system cleaning. You need to remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. After a professional fuel system cleaning, you’ll notice more power, better gas mileage and reduced exhaust emissions.
The cleaners also help prevent rust and corrosion in your fuel system and lubricate critical engine parts.
Fuel system cleaning is just one of those critical recommended service items that helps keep your sedan running strong. As with all maintenance, it can help avoid costly repairs that often result from not taking the right preventive steps. Boise drivers will notice the difference in how well their car runs. Check with your fr Napa AutoCare Boise tech to see when your car is scheduled for a fuel system cleaning.
An ounce of prevention really is worth a pound of cure for Boise auto owners.
Boise car owners know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine’s cylinders. This is the function of the fuel injectors.
There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.
Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.
For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same fuel efficiency. The turbocharged version delivers 350 horsepower.
Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved fuel economy.
Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.
Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.
When fuel injectors get dirty, their precision drops off. The spray pattern won’t be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and gas mileage for Boise auto owners as well as delivering less power to the engine.
Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we’re talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.
So keeping your fuel injectors clean is just good auto advice for Boise drivers. The best way to do this is to change your air and fuel filters regularly and practice other habits of good car care and preventive maintenance at Napa AutoCare Boise in Boise. Cleaning additives in your fuel can also help.
If you do end up with gum or varnish in your fuel system, you’ll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.

The good news is that with proper maintenance, Boise motorists will enjoy better fuel economy and their fuel injectors will last for a long time.
Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the sedan engine.
Boise motorists don’t need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your sedan engine will run.
Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your sedan ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.
The harder your fuel filter works, the more often it needs to be replaced. Check with your owner’s manual to find out how often it should be serviced and how long you can expect it to last. Boise drivers should change it before it becomes clogged. Your fr Napa AutoCare Boise service professional can help you with recommended fuel filter replacement schedules.
If your fuel filter becomes clogged, your sedan engine will sputter when you drive at highway speeds or when you accelerate rapidly. A clogged filter allows enough fuel to run the car at low speeds around town in Boise, but when you need a higher flow of fuel for faster speeds, or if you need a sudden burst of fuel, you just won’t be able to get it through the filter.
Boise motorists take note: A clogged filter is actually dangerous. If you need to accelerate suddenly out of the path of danger, you just won’t have the power to do it.
Fuel filters have a bypass valve. When the filter becomes clogged, the valve allows some fuel to bypass the filter so the engine can keep running – just not enough to be running well.
That means, though, that dirty, unfiltered fuel is entering your engine. Instead of clogging up your filter, that dirt is now getting into your fuel injectors where it can cause serious damage. Fuel injectors are expensive; fuel filters are cheap. It doesn’t seem like a difficult choice.
Fuel filters are the epitome of preventive maintenance. They are cheap and easy to change, but neglecting them can lead to expensive repair bills for Boise drivers. Some fuel filters are inside the fuel tank and cannot be routinely serviced – your fr Napa AutoCare Boise technician will be able to tell you if this applies to your vehicle.
Good car care means following recommended schedules for preventive maintenance, including changing your fuel filters. Take the auto advice offered in every owner’s manual and have your vehicle regularly inspected at Napa AutoCare Boise. It may save Boise drivers money by preventing costly repairs, but it will also repay them in improved fuel economy, safety and peace of mind.
Something you’re going to be hearing a lot about around Boise, Idaho is diesel engines. We’re not talking about semi-trucks and buses – We’re talking about diesel engine cars, pick-ups and SUVs.
Most people in Boise, Idaho are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import car makers offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven’t been available in Boise, Idaho. But that’s about to change.
In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in Boise, Idaho so we are now ready to start seeing more diesel options offered to Boise drivers over the next few years.
Why are so many Boise car owners interested in diesel engines? Well first off, diesel fuel is more energy dense. There’s more power in a barrel of diesel fuel than there is in a barrel of gasoline. The result? Better performance and improved gas mileage.
Diesel powered vehicles get about 20 percent better gas mileage. And as for power – why do you think that the majority of new heavy duty pick-up trucks are being sold in Boise with diesel engines?
If you think back to the late 1970’s and early 1980’s, you may shudder when you think of the diesel powered cars of the day – noisy, smoky, under-powered beasts that rattled and shook their passengers. Modern diesels sold in Idaho have evolved considerably.
They are quiet, clean – and powerful. They’re so refined that many Boise auto owners can’t even tell they’re riding in a diesel powered sedan. In addition to fuel savings, diesels generally last longer than gasoline engines because of their heavy duty construction.
Another thing the Boise green crowd takes advantage of is the use of bio-diesel in diesel vehicles. Bio-diesel is made from vegetable oil – even recycled cooking oil from Boise restaurants. There is a lot of buzz about Hybrid cars in Idaho. Look to diesel-electric hybrids in years to come to make a good idea even better.
Every year, manufacturers introduce new diesel models. Look for diesels in domestic light trucks, SUVs and passenger cars. Import auto makers have plans to bring more of their outstanding diesel engines to Boise, Idaho as well.
New Boise diesel owners need to know that properly maintaining a diesel engine is somewhat different than a gasoline engine. Fluid change intervals are different. Emissions control devices have to work harder to filter diesel fuel and to scrub the exhaust so you will need to pay attention to that. And the fuel injection system operates at much higher pressures than gas fuel injection systems, so it’s critical to keep your fuel system clean with a diesel.
The good news is that Napa AutoCare Boise in Boise is keeping up with the new diesel technology and will be able to advise you on maintaining your diesel.
When we tell you to look for more diesels on Boise streets, you won’t be looking for smoky tail pipes as a clue. You also won’t be listening for that familiar big rig rattle. And, you certainly won’t be waiting for them at the stoplight, because modern diesels are as quick as their gasoline counterparts.
From all of us at AutoNetTV, ten four, good buddy.
