Have you noticed an increase in price when you get a flat tire fixed in San Diego, or have your tires rotated? It might be the result of your TPMS, or Tire Pressure Monitoring System.The federal government began requiring a TPMS system on 2008 model year passenger vehicles and light trucks. Some 2006 and 2007 models may have them as well. The system has a warning light that is mounted on the dashboard that will go on if one of the tires becomes severely underinflated.Why the new requirement? Because underinflated tires are the number one cause of tire failure. Tire blowouts cause crashes and sometimes fatal accidents. Underinflated tires also need longer stopping distance and can skid, both of which also present dangers on CA roads. Many flat tires can also be prevented by proper tire inflation, and though this may seem an economic consideration, San Diego drivers who have changed a flat on the side of the road recognize that this has serious safety concerns as well.A ... read more

Bad air quality while you're driving around San Diego is nothing to sneeze at. But seriously, more and more vehicles these days come equipped with a cabin air filter. Since they're fairly new on the scene, a lot of folks don't know about them yet.These filters clean the air in the passenger compartment, or cabin, of your car or truck. They do the same job as the furnace filter you have at home. They can filter out particles as small as three microns. By contrast, a grain of sand is about 200 microns.So your cabin air filter can clean out dust, pollution, pollen and spores to keep the air in your car nice and clean. And just like your furnace filter, they need to be replaced when they get dirty. Check your owner's manual or ask your service advisor at John's Automotive Care, but they typically need to be replaced at around 12,000 to 15,000 miles (19,000-24,000 kilometers).The filter is usually either under the hood or under the dashboard. Some are a little tricky to get to, s ... read more

A lot of fuel is wasted in the San Diego area by dirty fuel delivery systems in vehicles.Let's start at the tank. The gas tank gathers dirt, rust and sediment over the years. That's why there's a fuel filter to clean the fuel after it leaves the tank. A dirty filter will rob the engine of the clean gas it needs to run efficiently.The fuel intake components get coated with gum and varnish over time. This results in fuel being delivered inefficiently and some of that gunk getting into the engine. A fuel system service at John's Automotive Care will leave your intake components as clean as a whistle.The big fuel thief is dirty fuel injectors. They deliver fuel to the engine at a specified pressure and in a particular spray pattern. When they're clogged, the fuel doesn't get atomized the way it's supposed to and doesn't get burned as efficiently.See your owner's manual or ask your San Diego service advisor at John's Automotive Care when a fuel system clean ... read more
