Because 90% of our driving decisions are based on visual information, unobscured vision is paramount. Which brings us to the topic of today's John's Automotive Care article: wiper blades. While this isn't the most exciting automotive subject, it's important. You wouldn't drive at night in San Diego with your headlights off, but a dirty or streaked vehicle windshield can catch the glare of the sun or on-coming headlights and make it just as difficult to see.Most of us in San Diego replace our wiper blades when they no longer do the job. They are so worn, hard or brittle that they can't clean the windshield. They may even be falling apart. In other words, we deal with our wiper blades from a failure perspective. We address them when they no longer function. The theory, "If it ain't broke, don't fix it," doesn't apply here. Instead, we should think about wipers blades as an important safety system that we should maintain rather than ... read more

A lot of San Diego drivers have asked whether or not they should use their severe service maintenance schedule, which is listed in their vehicle's owner's manual. It can be somewhat confusing, so we decided to consult an expert. Cricket Killingsworth is from QMI/Heartland, a manufacturer of automotive products and fluids. She's been in the automotive business for over 30 years and is a speaker, a trainer and a writer. Cricket says there's so much confusion on this topic because, "Most owner's manuals actually have two maintenance schedules. Sometimes these are called 'regular service' and 'severe service.' Sometimes they're simply called Schedule 1 and Schedule 2. A severe service schedule recommends that things like an oil change, air filter replacement and transmission service be done more often: either in fewer miles or in less time." Foreign and domestic vehicle manufacturers create a specific schedule for each vehicle they manufacture ... read more

Every San Diego car owner who has taken their car in for an oil change has been told that their engine air filter's dirty. Here's what goes into the determination of when to change the filter: First, your vehicle owner's manual will have a recommendation of when the filter should be replaced. Now, most air filters purchased in San Diego don't cost a lot to replace. It's just that CA people hate getting caught with an unexpected expense. On the plus side, though, changing a dirty air filter at John's Automotive Care can often save enough on gas to pay for itself before your next oil change in San Diego. Think about a dirty furnace filter in your San Diego home. When it's all clogged up, enough clean air can't get through. In your vehicle, that means that your engine can't get as much air as it needs to burn the fuel efficiently. So it makes do with less air and has to use more gas to move your vehicle around San Diego roads. Your vehicle actually needs about 12,000 ti ... read more

Just as our bodies need clean air to function properly, your vehicle engine needs clean air to operate efficiently. Let's go egghead for a minute. For every gallon of gas we burn driving on San Diego streets, 20 pounds of carbon dioxide comes out the tailpipe. Question: how can a gallon of gas that weighs a little over six pounds produce 20 pounds of carbon dioxide?The answer is that the carbon comes from the gasoline, but the oxygen comes from the air. You see, it takes about 12,000 gallons of air to burn a gallon of gas in your engine. Clearly, your vehicle needs a lot of air to keep going in San Diego. A lot of clean air is best. You've seen the pictures of people in Japan wearing face masks. They want some kind of filter to keep unwanted pollution and germs out of their lungs. Well, your vehicle also works better when its internals are clean. When your vehicle air filter is ... read more

Good vehicle care for us San Diego residents has always meant taking our vehicles in every spring and fall for a check-up. Vehicles needed routine maintenance to prepare them for the changes in weather. Today's vehicles aren't quite as sensitive to seasonal changes. Older vehicles required different weights of oil for summer and winter. But today's engines can run on the same oil all year. Both the engines and the oils have been improved.Antifreeze—or coolant as it's also called—protects the engine from both freezing and hot temperatures and thus is required by the engine year-round. Modern coolants don't have to be changed as often as they did in the past, but your owner's manual has a recommendation for when it should be replaced to extend cooling system life.Getting a spring and fall checkup at John's Automotive Care in San Diego for your vehicle is still good auto advice.First of all, there is a lot of preventive auto maintenance involved ... read more

Most San Diego folks occasionally have days when they've got a bunch of errands to run. Yesterday was my day off and I needed to fill the gas tank, pick up some groceries at my San Diego market, swing by the ATM and get the kids from school. I could have made four trips . . . but that would have been totally inefficient. Instead I got unusually organized and planned my stops. I hit the ATM first and got gas next. Then I went to the supermarket and picked up the kids on the way home. I was proud of my wise use of time and money.What does this have to do with your car? Well, back in the day, each of your engine's accessories, like the alternator and air conditioner, were powered by separate belts. A vehicle might have five or six belts. These days, vehicles have a single belt to run all the accessories. It's called the serpentine belt. A pulley attached to the vehicle engine's crank provides the power to turn the serpentine belt. On the engine in the video, the first accessory in line i ... read more
