Drive Defensively in CA

Car care is part of auto safety in San Diego. But the most important thing we can do to improve safety on CA roads is to drive safely.Defensive driving begins with the proper attitude. Have in mind that you won't let anyone take your safety away from you. You'll be aware of your surroundings, road conditions, other vehicles and hazards. And the first person to be concerned with is you: start with your own environment.Don't leave without securing all occupants including children and pets. Watch for loose items that can become projectiles during evasive maneuvers.Driving too fast or too slow increases the chance of an accident.Never drive impaired: Alcohol is a factor in half of all fatal crashes. Never drink and drive.Other impairments include being sleepy, angry, daydreaming or talking. If you suddenly wonder how you got where you are – you're not paying enough attention.Keep your windows clean and uncluttered. No fuzzy dice and stickers.Keep your car ... read more

What's up with Diesels in San Diego?

Would you be surprised to learn that about half of the passenger cars in Europe have diesel engines? You might also be surprised to learn that most manufacturers produce a variety of diesel-fueled cars for purchase abroad.Diesel-fueled vehicles haven't been as popular in the North American markets like CA. But that won't be true for long. North Americans are seeing a lot more diesel-fueled vehicles on the road. And we're not talking about buses and trucks. These vehicles will be passenger cars, pick-ups and SUV's.There are two reasons for this. The first is a recent change in environmental laws that have upgraded emissions standards for diesel fuel in North America. Diesel fuel in North America used to have higher sulfur content than European fuel, meaning that it was a dirtier fuel to burn. That was okay for larger vehicles, but the lighter-weight engines in passenger vehicles just couldn't tolerate it.But that high sulfur content is now a thing of the past. Fue ... read more

Hey San Diego Drivers, How Many Miles Are on Your Car?

Nowadays, San Diego drivers are paying more at CA gas pumps. For some families it adds up to several hundred dollars every month. That's got to come out of the budget somewhere. This is one of the reasons many CA drivers are putting off buying a new car. They plan on keeping their old vehicle for a year or two longer than before.Even now, 2/3 of the personal vehicles on our local San Diego, CA, roads have over 75,000 miles (120,000 kilometers) on them. The average age of vehicles is over nine years. And most people in the San Diego area can't afford to be stranded or inconvenienced by a breakdown. So following a regular maintenance schedule, like personal diet and exercise plans, is actually critical to preserving your investment.Determining what to do for a higher-mileage vehicle can be challenging because many owner's manuals don't publish service intervals after 60,000 miles (100,000 kilometers). Thus, San Diego drivers need to be better at keeping records and planning for prev ... read more

Have You Checked Your Headlights?

Like everything in the CA automotive market, there have been great strides in headlight technology in recent years. CA drivers can be safer at night because of it. Good headlights improve visibility on San Diego roads, enabling you to see farther. They also improve your peripheral vision, helping you to see the sides more clearly. The more you can see, the more quickly you can react to road conditions. This is because nearly half of traffic fatalities take place at night. And as San Diego resident population ages, everything that helps older eyes is welcome.Most new vehicles sold in CA come with halogen headlamps. A decade ago, halogens were exotic and expensive. Now that they are standard equipment, the price has come way down. Many luxury cars are equipped with high intensity discharge, or HID, headlamps. You have probably seen them on some San Diego roads; they're very bright and have a bluish tint.From behind the wheel, there is no doubt that HID headlamp ... read more

Good Timing: Proper Timing Belt Replacement Saves Money for San Diego Drivers

Knowing how their engine works can help San Diego drivers make informed decisions about auto care and prevent repairs to their vehicles. This is especially true when it comes to timing belts.An engine's power is generated in the cylinders. Inside the cylinder is a piston that moves up and down while the engine is running. Power is generated in a cycle that includes four strokes of the piston. First, the piston drops and a valve at the top of the cylinder opens to let in fuel and air. The piston then rises, which compresses the fuel and air. At this point, the spark plug fires, igniting the fuel and pushing the piston down. This downstroke transfers energy to the engine, which provides the power it needs to run. The piston rises again, and a valve opens to release the exhaust.All of this movement is orchestrated by a timing belt. The timing belt is so named because it keeps the pistons and valves operating in synch with each other, just as a conductor keeps all of ... read more

I Can See Clearly Now: Wiper Blade Replacement in San Diego

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

The Straight and Narrow: Power Steering Service at John's Automotive Care

Service to a vehicle's power steering system is part of preventive maintenance for  San Diego auto owners. This system provides power to the steering wheel so you can turn it with ease. Without power steering, all of the power to turn your vehicle's wheels would have to come from you.The central element of most power steering systems is a pump. The pump pressurizes the power steering fluid, and it is this pressure that provides auxiliary steering power. A belt connected to the engine usually powers the pump, although some systems use an electric pump. Some newer vehicles have an electric motor that directly provides the power steering boost.Pressurized fluid moves from the pump to the steering gear through a high-pressure hose. A low-pressure hose returns fluid to the pump. Power steering fluid cleans, cools and lubricates the system.San Diego drivers should remember that fluid levels in the power steering system should be checked at every o ... read more

Wheel Balancing at John's Automotive Care

So you love your job, and your family life is great. Congratulations! You have achieved balance. But can you say the same for your wheels? San Diego drivers can tell if their tires are out of balance by vibrations at higher speeds on CA roads. If one of the front tires is out, you feel the vibration in the steering wheel. If it's a back tire, you'll feel the vibration in your seat.Tires and wheels are pretty heavy. When a tire is mounted on a wheel at John's Automotive Care, it is usually not perfectly balanced. So the technician will spin the tire on a machine to determine where it's too heavy. He will then place weights on the wheels in strategic locations to balance it out. When a tire is out of balance, it actually bounces down the road instead of rolling smoothly. Since the average size tire rotates at about 850 revolutions per minute at 60 mph/97 kph, it is actually slamming into the pavement 14 times a second. That's where you get your vibration.Most people in San Diego are sur ... read more

The John's Automotive Care Guide to Tire Specs

You know you need newtires, but you're not sure what type. You look at a tire to get the size: 225, 50, R, 16, 92, H. All the way to the San Diego service center you keep repeating it over and over. You even say it over in your mind while waiting in line. Then you get to the counter and the manager asks what size you need. Then your mind goes blank.Tire size can be confusing for many San Diego drivers. There's so much on the side of the tire, and it's hard to keep straight.Even though there's a lot on a tire - if you know what it all means, it's actually more helpful than confusing for San Diego tire shoppers. Let's start with the size number.For example, let's say a tire reads: 225 50 R 16 92 H. The 225 part is the width of the tire in millimeters - the width between the sidewalls of an inflated tire with no load. The 50 is the aspect ratio - the ratio of the sidewall height to the tread width. Off-road tires will have a higher number and high p ... read more
