CA service centers have a menu board that lists the services they provide. Some San Diego drivers may not be familiar with all of the items on the board so here is a quick description of some of the typical services that might be listed.John's Automotive Care fuel system cleaning: Over time, the vehicle fuel system gets gum and varnish built up. A fuel system cleaning gets rid of that and cleans out the fuel injectors. Saves gas, by the way.John's Automotive Care headlamp replacement: Halogen and standard headlamps gradually fade. It's usually good to change them every year or so.John's Automotive Care inspections: San Diego drivers get inspections for many reasons. Maybe they're going on a trip or just want to make sure their vehicle's ready for a CA summer or winter. Maybe they just bought a used vehicle and want to give it the once over. An inspection may reveal some things that are broken or are get ... read more

If you've ever heard a squealing sound under your vehicle hood, chances are it was your serpentine belt. More importantly, the belt powers the alternator. The alternator creates electricity that's used by your vehicle's electrical systems and also charges the battery. Without the alternator, the battery will go dead after a short distance.The serpentine belt may also run the pumps for both the power steering (some are electric) and power brakes (some use vacuum boost).And, on most vehicles, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within optimal operating temperatures. On some San Diego vehicles, the water pump is powered by the timing belt instead of the serpentine belt.When they understand what it does, San Diego drivers realize that if it breaks, it affects a lot of systems. That's why vehicle manufacturers outline recommended replacement guidelines in the owner’s manuals. If thi ... read more

Sometimes we hear people in San Diego say, "What's up with all this maintenance stuff? Modern cars just don't break down." While it is true that today's vehicles are extremely reliable, they are also becoming increasingly complicated and use more exotic materials than ever before. All that complexity demands higher tolerances for everything. For example, most San Diego drivers don't realize how high tech automotive fluids have become,  fluids such as engine oil, transmission fluid, coolant and brake fluid.Did you know that a modern engine would not run for more than a few months using motor oil formulas from 30 years ago? Today's automotive fluids contain a much higher percentage of additives to protect your vehicle's components from premature wear and corrosion. Time and distances march on for all of our cars. Please don't think we're using scare tactics to get you to take care of your maintenance - but here are some personal stories we've heard t ... read more

Sometimes busy San Diego residents dream about going back to the “simpler” days of our grandparents. But if you could travel back in time and take a road trip around CA in a Model T, you might change your mind. The improved designs and quality of today's automobiles have significantly reduced the amount of time San Diego residents spend at the side of the road during breakdowns. With proper maintenance, today's vehicles can stay on the road longer than ever before.Some of those improvements, however, have led to higher repair costs. For example, older cars often broke down from vapor lock. Gas vaporized while traveling from the gas tank to the fuel pump. No gas, no power. The car quits going. The solution was simple — you just sat by the road until the car would start up again. Today's San Diego drivers would hardly tolerate that kind of inconvenience, and it's likely that yesterday's San Diego drivers didn't care much for it, either. So on today's vehicles, the ... read more

In our auto video today we'll be talking with Alan Peterson about myths surrounding automotive maintenance. You can lump these myths into the statement that "modern vehicles are so reliable, they are virtually maintenance free."Any good myth has some elements of truth. No offense to San Diego Bigfoot fans, but this maintenance-free myth has more evidence than most. If we look at some isolated areas of auto maintenance, we could conclude that maintenance isn't so important. But other areas would just as easily lead you to believe that maintenance is more important than ever.Here are some examples for our friends in San Diego. Some vehicles in San Diego no longer require chassis lubrication. They're made with self-lubricating materials and have sealed joints. There's literally no way to grease those joints. -Chalk one up for the myth.On the other side, some vehicles come with sophisticated variable valve timing. A lot of complicated parts are up in ... read more

There's a segment of the San Diego area population that's not committed to proper vehicle maintenance. Now, the ignition system in your vehicle is electronic and controlled by the engine management computer. Spark plugs rarely get fouled and will last for as much as 100,000 miles (160,000 kilometers). So tune-ups used to force you in to John's Automotive Care for service, and while you were there you just took care of whatever else was on the list.Also, in recent years, a large percentage of new vehicles in San Diego have been leased. These folks plan on turning the vehicle in after two or three years, so they haven't focused on the maintenance that helps a vehicle last longer.Given all that, what's the benefit to keeping up with factory scheduled maintenance? Well, your vehicle will perform better and return better fuel economy.Those benefits pay for themselves as they go along. The big plus is that major repairs are ... read more

Ask any San Diego man or woman if they've taken their vehicle in for preventive maintenance lately, and the answer may well be “no.” Surveys indicate that over 80% of vehicles on the road today are in need of some kind of repair or maintenance. Now, ask that same person why he hasn't taken his car in for care. The answer will probably be that he forgot or that he just didn't think about it. Most San Diego residents seem to have a hard time remembering about scheduled maintenance for their vehicles.Funny, because most of us in San Diego have no trouble remembering to wash our clothes, mow our lawns or brush our teeth. It isn't that we can't remember to take our vehicles for service; it's a matter of making it a priority.When it comes to our vehicles, San Diego drivers like myself, need to be a little more maintenance-minded. The fact is, we can choose to do it, or we might find ourselves being compelled to do it.For example, when we consiste ... read more

If you are a driver in San Diego and you aren't currently using synthetic motor oil in your vehicle, maybe now's the time to consider it. Need more information? Well, synthetic motor oil is a substitute for petroleum based oil. Synthetic oil doesn't gel or gum-up like petroleum based oil and it doesn't vaporize as easily. It protects better in severe driving conditions like stop and go driving around San Diego, as well as in very hot or very cold conditions. More and more new vehicles are being delivered with full synthetic motor oil, with the recommendation to use synthetic for the life of the vehicle. Why is this? Synthetic motor oil maximizes engine power and fuel economy. To see why, we'd need a microscope, so we'll have to settle for using our imaginations. The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is more slippery, a pile of pencils ... read more

About 90% of our driving decisions in the San Diego area are based solely on what we see. So having a good pair of windshield wipers is extremely important.Most San Diego drivers have experienced the frustration and fear of not being able to see clearly during a storm, or when our vehicle windshield is just dirty. In fact, it's estimated that 46,000,000 drivers across the nation are driving with wipers that can't adequately clear their windshield in a storm.It seems like our wiper blades are always at their worst when we need them the most. If that sounds like you, you've got plenty of company in the San Diego area. 78% of drivers only change their wiper blades after the blades function so poorly that they become a safety hazard.San Diego drivers need to change their thinking. Instead of blades being something to replace when they fail, we need to consider wiper blades as vehicle safety component. Then we'll stay ahead of the sto ... read more
