Diesel engines have been used extensively in Europe and Asia for many years. They haven't been as common in the San Diego area 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 San Diego diesel-fueled vehicles on the road, especially in passenger cars and SUV's.Diesels are popular in CA because they get better fuel economy 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 CA 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 w ... read more

San Diego residents know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your vehicle 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—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 vehicle engine.Direct injection engines burn fuel more efficiently than conventional vehicle 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 gas mileage. The turbocharged version delivers 350 horsepower ... read more

A driver of a large SUV loaded with equipment was heading on a 7-hour work trip when he stopped at a gas station to refuel.  When he went to restart his SUV, it turned over but wouldn't catch.  Try as he might, he was never able to get it started again.  Of course there are many things that can cause those symptoms, but the next day he had his SUV towed to a service repair facility.  Using their test equipment, they were able to pinpoint the problem.  His fuel pump had failed.  The pump, which was located in the fuel tank, had to be replaced, and after awhile he was back on the road, delayed, but happy to be up and running again.  What had happened is that the pump was not strong enough to deliver adequate  fuel to his engine, vital to being able to start it.  It had delivered just enough pressure in the morning to get it started the first time, but it was on its last legs.  He had been having trouble starting his SUV in the days leadin ... read more

There is no escaping it: things work better when you take care of them. Something most of us in San Diego can relate to is our computers. You've probably noticed how they get slower and slower over time. It takes longer to start up and programs take forever to load. Eventually, many of us just get a new computer at our nearest San Diego computer store. But computer experts know that there are things you can do to delay the need for a new computer purchase. You can run utilities that clean off temporary files and clean your memory registry. You can optimize your hard drive and a number of other things.What you're doing is maintaining your computer to make it efficient. It's the same thing with your vehicle. You maintain it to make it more efficient. It works the way it was designed to and that means it uses less fuel while you drive around San Diego. And you save money.To help organize our discussion, let's think of things that rob us of fuel economy in tw ... read more

In very simple terms, a fuel injector is a valve that squirts fuel into your vehicle engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected vehicle driving down San Diego roads.Most fuel injectors for gas engines are known in the San Diego automotive community as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine. A few have recently introduced gas direct injection systems on some engines. They are now available at some CA dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems. Although more complicated, direct in ... read more

Getting adequate fuel to your engine is very important for performance, fuel economy and safety. In order to accomplish this, your fuel system needs to be clean.Today's production cars have fuel injectors, rather than a carburetor. The injectors need to be cleaned from time to time in order to deliver the fuel with the correct pressure, spray pattern and volume.San Diego drivers can buy fuel system cleaners that you pour into your gas tank to help maintain an already clean fuel system; however, they can't do a major cleaning. For that, you need to see Pacific Highway Auto Repair in San Diego. We have the tools and chemicals to do the job right. Our friendly and knowledgeable team at Pacific Highway Auto Repair can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently.

Let's talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions in our CA environment, automakers will have a number of alternatives for San Diego drivers 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 to San Diego drivers are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower gas mileage and when gas prices are low, E85 can be more than straight gasoline.San Diego drivers should only use E85 if they 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 CA  f ... read more

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 use fuel filters. For more information about your fuel filter, visit Pacific Highway Auto Repair at 4306 Pacific Highway in San Diego, CA 92110.Please call 619-299-7700 to make an appointment. Generally speaking there's not a lot of dirt in our San Diego area 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 vehicle 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 vehicle ages. It'll get clogged sooner and need to be rep ... read more

Hi San Diego residents. 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.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.  It also 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 detrim ... read more

Is your vehicle sometimes hard to start early in the 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 vehicle'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 San Diego vehicles 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 parts of your fuel system.Some San Diego residents are interested in buying fuel system cleaners that they can pour into their 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 Pac ... read more
