Whether we're trying to save money, save gas or save the environment, most of us San Diego drivers have an interest in decreasing fuel consumption. We've all heard about ways to save money on gas in CA, but does it really add up to much? How much can we boost our fuel economy through preventive maintenance and more courteous driving?The US government has a website that actually answers that question. Let's look at some of the data and find out if any of these fuel-saving ideas are really worth the effort. We've all heard that a tune-up can improve gas mileage. It turns out that it can save us 4% at the pump. At $3.50 a gallon, that's 14¢ per gallon in savings, and at $4.00 a gallon, that's a 16¢ per gallon savings.Other common repair items can also save you at the pump. For example, if your oxygen sensor is faulty, it's not delivering the information to your engine's computer that allows it to calculate the right fuel-to-air ratio. The result? The f ... read more

At John's Automotive Care we've had a lot of San Diego customers asking how they can make their vehicles last longer. These questions are actually a reflection of a trend that's been building for several years in CA. The median age of personal vehicles is now over nine years. And 33 percent of all vehicles on the road have over 75,000 miles (120,000 km) on them. It looks like it's going to keep heading in that direction for a while. With high fuel prices, a lot of CA folks are putting off buying a new car. So let's say you're one of the average in the San Diego area; you've got a nine-year-old car with 80,000 miles (130,000 km) on the odometer. What can you do to make it last another year or two?Let's start with the premise that there's no reason that a modern car can't run for 200,000 miles (320,000 km) with proper care in San Diego. The engineering and manufacturing quality is there.Of course, some parts will wear out along the way, but there's no reason fo ... read more

Let's talk about something critical for all San Diego drivers: your brakes. Your vehicle is heavy, and it takes a lot of muscle to bring it and your passengers to a safe stop – so everything needs to be in good working order. Here's an explanation on how your disc brakes work: The wheel hub keeps your wheel attached to your vehicle. The brake disc – or rotor – is attached to the hub and rotates with the wheel as you drive around San Diego. Your brake pads clamp onto the rotor to slow the wheel.The brake caliper straddles the rotor and squeezes the rotor to slow it down. The calipers contain brake pads which press on the rotor when you put your foot on the brake. The brake piston causes the calipers to squeeze and release as you use your vehicle brakes.Your brake pads start to wear the first time you step on the brakes. Eventually ... read more

A lot of us drivers are asking ourselves the same question lately: how can we save on fuel? San Diego area residents are all cutting back, if not in fuel consumption, then in other areas of our lives. Preventive Maintenance Preventive maintenance is an important way people in San Diego can conserve fuel by improving fuel economy. And one of the easiest and most effective ways to do that is to keep the oil in our vehicle adequate and clean.Oil lubricates your vehicle engine and keeps it running smoothly. If you're running low, there is increased friction in your engine. Friction creates drag, which means it takes more fuel to keep the vehicle motor running. This all translates to lower fuel economy.Check your oil to make sure the engine is getting all it needs. Your owner's manual and service advisor at John's Automotive Care will tell you the proper weight and type of oil for your vehicle. Responsible Car Care Dirty oil grits up your engine, which ... read more

The Check Engine Light strikes fear into the hearts of some San Diego drivers, and is totally ignored by just as many. Just what it means is a mystery to most people. Let's get the urgency issues out of the way first. If your Check Engine light is flashing, that means that something is wrong that could cause engine damage. Naturally, you need to get that taken care of right away. If your check engine light is flashing, you shouldn't drive at high speeds, tow or haul heavy loads. Take it easy all the way to your San Diego service center. If the light is glowing steadily, you should keep an eye on it for a day or two. If the light doesn't go off, schedule an appointment with your friendly and knowledgeable pros at John's Automotive Care to get it checked out.Some more information on how the Check Engine light works may be helpful f ... read more

CA residents may have heard that vehicles don't need their oil changed as often as they used to. That's true. But it's not the whole story.Owing to improved engine technology and higher oil quality, most newer vehicles can go longer between oil changes than their older counterparts.So what is a good time interval for oil changes? How do CA residents know when to change it? And why do we change it in the first place?Oil lubricates a vehicle's engine, which protects it from friction damage. Over time the oil can collect dirt and contaminants that inhibit its performance. But dirty oil isn't the only problem for CA residents. What you really want to avoid is called oil sludge.Oil sludge is caused by moisture in the oil and by hot spots in your engine that burn off oil. This sludge is a gooey gel that can clog engine passageways, which can block lubricants from reaching vital engine parts. The result can be engine wear or even engine failure.Sludge forms rapidly in an engine that is driven ... read more

If you're a quart low in your vehicle, there isn't enough motor oil to lubricate your engine properly. The extra friction causes drag that reduces fuel economy while you're driving around the San Diego area.The same goes for dirty oil; it doesn't reduce friction properly. The result is you get to watch those numbers at your local San Diego gas pump rolling higher and higher.The transmission also needs the proper amount of clean fluid to do its work. When it's in need of service, the transmission drags your fuel economy down.So keep it clean at John's Automotive Care  and give yourself a fighting chance.

When I was a kid, my dad always made sure he took the cars in for Spring and Fall checkups. I was telling a friend that it's about time to get into John's Automotive Care for a checkup and he said that he read on the internet that modern cars don't need seasonal service.My friend is (technically) right about some things, but from a practical standpoint, a seasonal check up still makes sense.Back when my dad was teaching me about how to take care of the family vehicle, most of them used a different weight of oil in the winter and in the summer. But most of today's modern engines run the same oil year round. High-tech engines and high-tech motor oils are better able to handle the seasonal changes.Your owner's manual or San Diego service advisor at John's Automotive Care can tell you the right oil to use.Of course, you're concerned about the coolant or antifreeze. You don't want to overheat in the CA summer or freeze ... read more

Having trouble with your fuel system? Bring your vehicle into John's Automotive Care for a check up.In today's John's Automotive Care auto post,we're talking about fuel system cleaning. The first thing to know is how important it is to have a clean fuel system. San Diego residents need fuel to go, and the cleaner the fuel system, the more efficiently the fuel will burn. That means more power and better mileage .A clean fuel system saves money for San Diego drivers at CA gas stations. We guess you could say it all starts and ends at the pump. One of the most important things San Diego residents can do to keep their vehicle fuel system clean is to buy good quality gas. Major brands have detergents that keep gum and varnish from rapidly building up in the fuel system.So buying cheaper gas in CA can actually be more expensive for San Diego drivers in the long run. Now, most cars on CA roads are more than five or six years old. That means they've had time for some dirt ... read more

Shopping for tires in San Diego can be bewildering because there are many choices. Let's simplify. There are four main classifications of tires, each designed for different purposes.First off, there are summer tires. Those who buy summer tires in San Diego are looking for maximum summertime performance. The rubber is a little softer to help stick to the road on fast corners on CA roads. The tread has wide blocks at the shoulder to stiffen the tire in turns. The tread design can handle rain but really isn't set up for snow and ice. Next comes winter tires. San Diego people buy winter tires because they still like performance driving when it's cold and slippery on CA roads, so they need a tread design that'll really bite into ice and snow. The rubber compound is formulated to stay pliable when temperatures drop below 45 degrees F/7 degrees C so they get great traction even on dry roads. On the other end of the winter tire spectrum are tires designe ... read more
