We all know about winter tires.  But did you know there is such a thing as summer tires? Most people have all-season tires on their vehicles.  They work pretty well in a variety of weather conditions.  But if you want better handling and performance, you might consider switching to summer tires.  Here are a few things you should know about them. Summer tires are good for high-performance vehicles like sports cars and luxury SUVs, but they don't have to be limited to those. They have a different tread pattern than all-season tires, with generally shallower grooves and more rubber that contacts the road.  The rubber is made of a stickier compound good for taking corners at higher speeds.  Plus it is engineered so it stays firmer the hotter the temperature gets.  Here's a bonus.  That design also works well in warm, wet weather.  It makes sense, since more the more rubber that's touching the concrete or asphalt when it's slippery out, the bette ... read more

Those who know vehicles believe the steering system may be the most vital component of them all. Perhaps you've found over the years your steering has gotten loose. Or maybe suddenly, your steering wheel has gotten very hard to turn. Let's steer you in the direction of understanding why this may be happening. First, loose steering. This can likely be the result of wear and tear on the components that connect the steering mechanism with the wheels. Those parts can be ball joints, Pitman arms or tie rods. These parts take a lot of abuse on the road, thanks to railroad tracks, potholes, uneven surfaces: you name it. It's important that they be checked regularly and maintained at John's Automotive Care. Second, the hard-to-turn wheel. Virtually all vehicles on the road have power steering. There are a couple of different types, though, so let's deal with each. By the way, when they fail, your vehicle's steering can suddenly go from easy peasy to really hard to control. Some vehicles have h ... read more

We've all been through it. The vehicle ahead of us kicks up mud, slush, snow or salt on our windshield and we can't see a thing.  And not being able to see a thing when we're driving?  Not a good thing. Debris on a vehicle's glass can be blinding when driving directly into the sun.  And other things can ruin visibility: scratches on the glass, fogged windows, mineral deposits.  So lets make one thing clear:  Your windows.  Here are some tips. Number one rule, don't use abrasives on glass. That means no gritty cleaners that are made for metal.  Avoid at all costs those dark green abrasive pads on some kitchen sponges that are made to clean metal pots and pans UNLESS the manufacturer specifically says they can be used on glass. Use the appropriate cleaner for the substance that's being cleaned off. Special automotive glass cleaners are available, and your John's Automotive Care service advisor can make recommendations. Vinegar can work wonders. Sometim ... read more

Do I keep my old vehicle or buy a new one? It's a question most San Diego drivers ask themselves at some time or another.Generally, what it comes down to is the choice between a car payment and the possibility of repair bills. Most of the time, we want to choose the car payment because we don't like the inconvenience and uncertainty of vehicle repairs. But that payment has a detrimental effect on our budget and bank account.Edmunds.com is a great website to help you with your decision. This site uses repair histories to calculate the average repair bills for specific makes and models of cars. You can plug in the information for your vehicle and get an estimate on what it will probably cost you to continue owning that vehicle.Now, Edmunds.com isn't a crystal ball. It can't know what will happen to your specific vehicle. But it can guide you in knowing how much money to budget for the repair and maintenance of your vehicle ... read more

You swap your winter boots for flip-flops in the summer.  Why not change your winter engine oil for summer, hot-weather oil?  While it may seem like it makes sense, there's some good news.  Most drivers don't have to, and here's why. Engine oil can be made in different thicknesses.  That thickness is called viscosity, how easily it flows.  Now, it makes sense that the hotter it gets, oil gets a little thinner and doesn't lubricate as well.  So if you used a thicker oil in the summer, it's logical that it would protect better in the hotter weather.  While there was a time when oils could be only made in one viscosity, times have changed.  Using an ingenious formula, oil can now be created that changes its viscosity (called "multi-viscosity") as the temperature rises and falls.  It self-adjusts to match the conditions.  Now that's what I call a great invention. In most temperate climates, you don't have to swap out the type of oil you use ... read more

Your vehicle has lots of doors including that one usually near the back on the vehicle's side.  That's the fuel door, something you use every time you gas up.  These endure hundreds of open-and-close cycles, usually without any problems.  But when they act up, it can be a major inconvenience for you. When they stick in the "open" position, it can present real dilemma.  You can still pump your gas, but do you just drive around with that flap sticking out the side? What happens if someone steals the gas cap or it gets damaged? What happens if it rains? Yep, it's decision time. A fuel door that sticks open can be due to a number of factors.  The hinge on the door may have broken, possibly from corrosion or it may have been hit sometime.  Some vehicles have a cable that operates the door and it could be loose.  The latch that holds the door shut could have broken or it, too, could be bent from something hitting it.  You probably want to take care of ... read more

If you haven't shopped in the San Diego area for a new vehicle recently, you're likely to experience some sticker shock. It seems everything is costing more these days. And when you consider the price of auto financing in San Diego, and insurance, the idea of hanging on to your old vehicle for a few more years gets even more attractive.On the plus side, vehicles these days are engineered to last for 150,000 miles (250,000 km) or more. So why don't they? Usually it's because San Diego drivers don't stay on top of preventive maintenance. Good vehicle care at professional automotive service centers like John's Automotive Care in San Diego is the key to getting the most mileage out of your vehicle.Too often, San Diego vehicle owners are inclined to wait until their vehicles develop an obvious problem and take them in for repairs instead of maintenance. Repairs can be expensive, but allowing routine vehicle maintenance t ... read more

Automotive design has come a long way since the days of the Model T, especially when it comes to safety technology.  You can thank computers for a lot of the latest innovations.  Here are a few that have been making their mark in recent years. Adaptive cruise control.  This is cruise control with a brain.  Not only will adaptive cruise control keep your vehicle going at a steady speed, it will also slow it down and even stop it if the vehicle ahead of you slows down and stops.  Automatic emergency braking.  We've all been distracted while driving, and you've probably been in a situation where the driver ahead of you has suddenly stopped.  Or maybe your attention wandered for a minute and you looked up to see your vehicle closing in fast on the car ahead of you.  (After all, there are a lot more distractions in your vehicle these days.)  New systems that use cameras, lasers and other types of sensors will warn you to start braking.  If y ... read more

Driving along, your exhaust system's rumbling so loud that people turn and stare at you pass by.  You're wondering when the police are going to pull you over for illegal noise. Your mind immediately thinks, aha! A broken muffler.  Well, your exhaust system is composed of many more parts than just a muffler.  Your engine makes power because of thousands of tiny explosions from detonating fuel.  Those explosions make a racket, so engineers came up with a system that acoustically dampens that sound in addition to getting rid of harmful exhaust. In the engine is the exhaust manifold that looks like several pipes that join up into one pipe.  It directs exhaust to the catalytic converter. The catalytic converter converts harmful gases into less harmful gases using certain chemical reactions.  Then comes the muffler that has baffles inside to quiet the sounds of your engine noise.  Finally: the tailpipe. All of those pipes and parts are joined together by cl ... read more

Some problems are easy to diagnose on a vehicle; others aren't.  Figuring out what's wrong with a malfunctioning turn signal sometimes fits into both categories.  By the way, if your tempted to just leave your broken blinker broken, remember you can get a ticket for not using them, not to mention you are missing a great chance to communicate your intentions to other drivers on the road. There can be lots of signals that your signals are on the blink.  Does only the driver's side signal not work or the passenger's side? Do your hazard signals work? Do the lights illuminate but not flash? Can you see the indicators on the dash blinking? Do your turn signals turn off after you've finished your turn or do they stay on?  These are all great clues for the technician. Here's one common symptom to take note of.  Your signal all of a sudden starts blinking much more quickly than it used to.  It could be a simple as a burned out bulb.  But there are many differ ... read more
