Your fuel system needs to be clean to do its job properly. When it gets dirty, the results are lower engine performance, reduced fuel economy and impaired safety. It can even lead to costly repair bills for San Diego drivers. So keep your fuel system clean as part of your routine preventive maintenance.Fuel injectors have replaced carburetors in most of today's vehicles. These injectors deliver better fuel economy than a carburetor, but they can be compromised by rust, dirt and other contaminants. They need to be clean to maintain the correct pressure, spray pattern and volume of delivered fuel so that the vehicle engine can run at peak efficiency.There are products on the market that San Diego vehicle owners can add to their gas tank that will help keep your fuel injectors clean. These products will keep a clean fuel system clean but have trouble cleaning a system that has already gotten gummed up.If your fuel system needs a major cleaning, John's Automotive Care can ... 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

There are a lot of drivers in San Diego who are due for a differential service, but had never heard of a differential before.With front-wheel drive being so common in CA these days, the differential is just taken care of during a transmission service, so most San Diego folks don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of your mind. It's not uncommon for people in San Diego to not know they have a differential, let alone know that it needs service.To better understand what a differential does, think about a track at any CA high school. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner h ... read more

  Hello San Diego, let's talk about brakes. But the mechanical aspects of the brakes themselves are just one issue. There's also the power brake pump and brake fluid. And then there are the tires, which are critical to the effectiveness of the brakes.Let's step back. A new vehicle or truck rolls off a local San Diego showroom floor. It has brand new brakes with brand new brake pads. The brake lines and pump are filled with fresh fluid and are completely clean inside. And the tires are brand new, with full tread. It is ready to go.Naturally, braking power is at its peak performance. Now the miles/kilometers start to add up on the vehicle. San Diego drivers tend to focus on the brake pads. In the automotive business, the pads and shoes on drum brakes are called the friction material. That's because they provide the friction used to stop the vehicle. The pads are designed to be effective throughout their useful life – it's not until they are worn so thin as to be out of 'specs ... read more
