Whether we're trying to save money, save gas or save the environment, most of us San Diego drivers have an interest in decreasing fuel consumption. We've all heard about ways to save money on gas in CA, but does it really add up to much? How much can we boost our fuel economy through preventive maintenance and more courteous driving?The US government has a website that actually answers that question. Let's look at some of the data and find out if any of these fuel-saving ideas are really worth the effort. We've all heard that a tune-up can improve gas mileage. It turns out that it can save us 4% at the pump. At $3.50 a gallon, that's 14¢ per gallon in savings, and at $4.00 a gallon, that's a 16¢ per gallon savings.Other common repair items can also save you at the pump. For example, if your oxygen sensor is faulty, it's not delivering the information to your engine's computer that allows it to calculate the right fuel-to-air ratio. The result? The f ... read more

At John's Automotive Care we've had a lot of San Diego customers asking how they can make their vehicles last longer. These questions are actually a reflection of a trend that's been building for several years in CA. The median age of personal vehicles is now over nine years. And 33 percent of all vehicles on the road have over 75,000 miles (120,000 km) on them. It looks like it's going to keep heading in that direction for a while. With high fuel prices, a lot of CA folks are putting off buying a new car. So let's say you're one of the average in the San Diego area; you've got a nine-year-old car with 80,000 miles (130,000 km) on the odometer. What can you do to make it last another year or two?Let's start with the premise that there's no reason that a modern car can't run for 200,000 miles (320,000 km) with proper care in San Diego. The engineering and manufacturing quality is there.Of course, some parts will wear out along the way, but there's no reason fo ... read more

Let's talk about something critical for all San Diego drivers: your brakes. Your vehicle is heavy, and it takes a lot of muscle to bring it and your passengers to a safe stop – so everything needs to be in good working order. Here's an explanation on how your disc brakes work: The wheel hub keeps your wheel attached to your vehicle. The brake disc – or rotor – is attached to the hub and rotates with the wheel as you drive around San Diego. Your brake pads clamp onto the rotor to slow the wheel.The brake caliper straddles the rotor and squeezes the rotor to slow it down. The calipers contain brake pads which press on the rotor when you put your foot on the brake. The brake piston causes the calipers to squeeze and release as you use your vehicle brakes.Your brake pads start to wear the first time you step on the brakes. Eventually ... read more

San Diego area residents are all cutting back, if not in fuel consumption, then in other areas of our lives. Preventive Maintenance Preventive maintenance is an important way people in San Diego can conserve fuel by improving fuel economy. And one of the easiest and most effective ways to do that is to keep the oil in our vehicle adequate and clean.Oil lubricates your vehicle engine and keeps it running smoothly. If you're running low, there is increased friction in your engine. Friction creates drag, which means it takes more fuel to keep the vehicle motor running. This all translates to lower fuel economy.Check your oil to make sure the engine is getting all it needs. Your owner's manual and service advisor at John's Automotive Care will tell you the proper weight and type of oil for your vehicle. Responsible Car Care Dirty oil grits up your engine, which ... read more
