Your Imports requires plenty of clean fuel to run. When your fuel isn’t clean, your fuel injectors can start to become clogged up. When this happens, your Imports engine may not get the proper amount of fuel at the correct pressure to run efficiently. This hurts fuel economy and performance as you drive around San Diego. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.
That’s why all vehicles, including Importss, come equipped with a fuel filter somewhere between the engine and the fuel tank. The job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and holds them out of the fuel stream. Of course, the filter will eventually get clogged up and need to be replaced at FTS Auto Repair.
If your fuel filter is clogged, the Imports engine can’t get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your engine running, but doesn’t protect it from contaminated fuel.
You may find that you need to change your fuel filter at FTS Auto Repair more frequently as your Imports ages. Over the years, additional sediment and rust accumulates in the fuel tank and can be drawn into the fuel system. Your fuel filter stands guard at the gates to your engine to protect expensive parts and to maintain performance and fuel economy.
For those of you in San Diego Ca who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.
For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same gas mileage. The turbocharged version makes over 350 horsepower.
So what are the differences from a conventional engine?
The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it’s then drawn into the engine with the air.
With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.
First, the fuel is squirted in at hundreds of times more pressure, so it’s atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.
Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can’t do its job as well. That means less power and worse fuel economy for your Imports and can lead to damaged fuel injectors.
Replacing fuel injectors isn’t cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we’re talking mortgage payment-range to replace a set of diesel injectors.
A professional fuel system cleaning from FTS Auto Repair gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they’ll last a long, long time.
The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around San Diego Ca use fuel filters.

Generally speaking there’s not a lot of dirt in our San Diego Ca auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That’s because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your Imports is five years or older, it can actually have a fair amount of sediment built up.
That just means that the fuel filter has to work harder as your Imports ages. It’ll get clogged sooner and need to be replaced more often.
A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That’s because enough fuel is getting through around town, but when you need more fuel for speed, enough just can’t get through the filter. Obviously, that could be dangerous if your car or truck can’t get enough power to get you out of harm’s way.
For just that reason, fuel filters have a bypass valve. When the filter is severely clogged, some fuel can bypass the filter all together. Of course that means that dirty, unfiltered fuel is getting through to be burned in the engine.
This dirt can then clog and damage your fuel injectors. Now injectors are not cheap to replace, so you don’t want to cause them damage just because you didn’t spend a few bucks to replace a fuel filter.
You know, in a way, the fuel filter can be the poster child for preventive maintenance. It’s a little part, it’s simple and it’s cheap to take care of. But if it’s neglected, it could lead to thousands of dollars of repair bills.
Those auto service schedules in your owner’s manual are there for a reason. If ever you don’t understand a recommended service, just ask your San Diego service advisor at FTS Auto Repair. We’ll be happy to explain.
One topic that hits the news in San Diego on a regular basis is the price of gas. The answer for some people in San Diego is to buy a more fuel efficient vehicle. For the rest of use, we need to improve our fuel economy anyway we can.
Following recommended service intervals by coming into FTS Auto Repair is one of the best ways to keep your car running efficiently. That means better fuel economy. When you give it some thought, it only makes sense. Dirty oil or transmission fluid can’t lubricate or clean. That means more drag which reduces fuel economy.
Dirty engine air filters are another efficiency pirate. They rob your engine of enough air to effectively burn the fuel, so you need more gas to get the job done. Replacing a dirty air filter can pay for itself in fuel savings before the next oil change.
You can imagine what dirty fuel injectors can do to your Imports as you drive around San Diego. If your owner’s manual recommends a fuel system cleaning, come into FTS Auto Repair and ask us to get it done for you.
A simple, but very effective way to save gas is to keep your tires properly inflated. Low tires can cost you up to a mile per gallon. Check your tire pressure when you gas up – or at least once a month.

A question for our San Diego Ca motorists: How long have you been enjoying the romantic glow of your check engine light?
Hey, it’s not there to create ambiance; it’s a warning that something’s wrong. When your check engine light comes on get it checked at a capable San Diego Ca service station.
Many conditions that cause the check engine light to come on affect fuel economy. Some very dramatically.
Always make sure you tighten your gas cap until it clicks. A loose gas cap can cause a false sensor reading that’ll make the check engine light come on.
If your date’s eyes are smoldering in the reflected glow of the check engine light, try to think of all the gas money you’ll save by getting it fixed. Give us a call when you are ready: 858-279-7724
At FTS Auto Repair we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV’s. But our Ca friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there’re nearly as many diesel powered passenger cars as there are gasoline.
Here’s who’s announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in Ca.
You may ask, why has it taken so long getting to Ca and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that Ca diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines. Recent government mandates to remove sulfur now opens up Ca to the engines the rest of the world’s been enjoying for a long time.
Why are diesels so popular worldwide? Well, for starters, diesels get up to 30% better fuel economy than gas engines. And they last a lot longer. And modern diesel engines are refined, quiet and powerful – and there’s none of that black smoke we used to see.
Some people may think that diesels create more pollution. But, you need to rethink diesels. Environmental pollution standards for diesel cars and light trucks are scheduled to be as strict as they are for gasoline vehicles. A modern diesel engine is as clean as a gas engine.
You may also have heard a lot in the news about bio-diesel. The exciting thing about diesels is that they’re not limited to fossil fuels. They can run on fuel made from vegetable oil. There are refineries that make diesel fuel from cellulosic waste like woodchips from lumber mills. There’s even this cool new process where a special strain of algae is used to convert carbon dioxide, water and sunshine into bio-diesel. That’s still a ways off, but you can see that diesel can become a sustainable source of fuel.
And, there are not a lot of trade off’s with diesel in terms of performance. A modern passenger car diesel is very smooth, quiet and quick. Most folks wouldn’t notice any difference. For those who tow trailers and haul heavy loads, diesels will be an improvement.
Now diesel engines are heavy duty, so they cost more than gas engines. But they get better fuel economy – so the break-even point is largely dependent on the difference between Ca gas and diesel prices at the pump and how many miles you drive. And diesels have a higher resale value.
Now, let’s get back to diesel maintenance. You have to keep in mind that most of the new diesels are just coming in, or will be over the next couple of years, so we don’t have the maintenance schedules to make direct comparisons yet.
But going off what we already have in Ca, we can expect fluid drain intervals to be similar to gasoline engines. Diesels do require very clean fuel, air and oil, so their filters are much higher capacity than gasoline filters and cost more. The engine air filter needs to be changed more frequently as well.
Repair costs are similar. As with gasoline engines, proper maintenance is the key to long engine life and to avoiding repairs. So pretty much what we have come to expect with gas vehicles; coolant system service, transmission service, power brakes, power steering, differential, filters, fuel system, and so on. And the payoff for you, if you’re the kind that likes to keep your vehicles for a long time, is that a properly maintained diesel engine can last for hundreds of thousands of miles.
There’s not much we can do about the price of gas in San Diego Ca, but we do quite a bit about how much we use as we’re driving on our San Diego streets.
Our driving habits can dramatically affect our fuel economy.
The first thing we can do is watch the ‘go-pedal’. Hard acceleration just sucks the gas. Gently leave stop lights and plan lane changes so you don’t need to floor it. That can save you hundreds of dollars a year.
Go a little slower on the freeway to San Diego. Once you’re going more than sixty-five miles an hour your fuel economy starts to drop dramatically. Leave early so you don’t need to rush to be on time. And cruise control is your friend – steady speed uses less gas.
Plan errands ahead. Make fewer trips by combining errands.
Hey at current gas prices, a lead-foot might as well be a gold foot.

All modern vehicles come with fuel injection systems, so it’s a topic we all need to know something about. All new cars and trucks sold in San Diego, Ca over the last 30 years or so have come with fuel injection systems.
The 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 San Diego, Ca. 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 sophisticated part.
FTS Auto Repair can help you 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. The fuel needs to be 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 wastes fuel.
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. Its real tempting to shop for bargains with fuel prices as high as they are, but major brands in the San Diego, Ca area have better detergents and additives and deliver consistent quality.
What about a good fuel filter? The fuel filter is the next device in 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 manufacturer 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 we’re 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 San Diego, Ca that can clean fuel injectors. They’re best used to prevent fouling in the fuel injectors. Many can’t clean a seriously gummed up injector – that requires a professional deep cleaning. But putting the cleaner in the fuel tank after you’ve had FTS Auto Repair 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 Imports may be ready for a fuel injector cleaning.

This fuel saving tip is so simple, no one from here to Terrasanta will believe it. It has to do with your gas cap.
The first thing is to make sure it’s screwed on tight. If it’s loose, gas vapor will be constantly leaking out; wasted gas.
And air will get in and that can cause your oxygen sensor to read incorrectly and the oxygen sensor will tell the engine management computer to adjust the fuel-air mix and, well, you get the picture; you’ll be burning more gas around Terrasanta than you need to.
This could cause the check engine light to come on as well.
A worn gas cap can have the same effect. If you constantly smell gas when you walk by your tank, you might need a new gas cap.
So, twist your cap until it clicks three times – that means it’s on tight. Have your Terrasanta area service advisor at FTS Auto Repair inspect the cap to see if it needs to be replaced.
See, I told you it was simple.
Don’t forget to call FTS Auto Repair at 858-279-7724 for an appointment to optimize your Imports for better fuel economy. Ask us about Factory schedueled services.
Let’s talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions to our San Diego environment, automakers will have a number of alternatives for us very soon.
For instance, Flex Fuel vehicles are already available in the San Diego area. Flex Fuel vehicles can run on gasoline or on E85 fuel. E85 is a mixture of 85 percent ethanol and 15 percent gasoline. The ethanol is made from corn.
The benefits are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower fuel economy and that when gas prices are low, E85 can be more expensive than straight gasoline.
You should only use E85 if you have a Flex Fuel compatible engine. Flex Fuel vehicles have special seals and gaskets that can stand up to the high alcohol content of E85. Using E85 in a regular engine can lead to gas leaks and fires.
Diesel engines have been around the San Diego area for a long, long time. Modern diesels are very refined and fuel efficient. Diesel fuel can be made from renewable sources like vegetable oil, too. Diesel fuel from algae and sunlight is reported to be pretty close to being commercially viable.
There are also a number of natural gas vehicles on our San Diego roads. Gasoline engines are adapted to run on compressed natural gas. It’s less expensive than gasoline and burns very cleanly. You can even refill it with a special pump from your gas line at home.
Natural gas engines don’t make as much power and don’t get as good of mileage, but they cost less per mile to run. The big inconvenience is that the tank that holds the compressed natural gas takes up a lot of room; even your whole trunk! And there may not be places to refuel on a road trip from San Diego.
Plug-in electric vehicles are now available in our San Diego area. Battery technology is the limiting factor right now. Electric cars have a limited range and are really best for use close to home. As battery technology advances, electric cars will perform closer and closer to conventional power plants.
That brings us to hybrids. There are a bunch of hybrids on our San Diego roads, with more to come. Hybrid technology combines internal combustion engines with electric motors.
A mild hybrid has a regular gas or diesel engine that’s assisted by the electric motor. The electric motor can propel the vehicle by itself up to a certain speed under gentle acceleration. There are mild hybrids in full-sized pickups and SUVs. They deliver city fuel economy similar to their highway ratings.
A full hybrid will rely primarily on the electric motor for power. It’ll have a small gas or diesel engine that generates electricity for the batteries.
Another breakthrough technology is hydrogen fuel cells. Fuel cell vehicles use hydrogen to generate electricity. Several global car makers have prototypes on the road. The appeal is that the only thing that comes out of the tail pipe is water vapor. It’ll take some time to build a national infrastructure of hydrogen fueling stations before there’s widespread use.
A quick word about safety around hybrid and electric vehicles. Unlike the battery in your current family car, these carry enough voltage to kill you. Never mess around under the hood or with the batteries or electrical wiring. Your San Diego service technician at FTS Auto Repair is trained to safely disable the flow of electricity before performing maintenance or repairs on the vehicle.
Hybrids are really not do-it-yourself vehicles unless you’re specifically trained on hybrid systems.
The job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and holds them out of the fuel stream. Of course, the filter will eventually get clogged up and need to be replaced at FTS Auto Repair.
