You may have heard the old saying, "My get-up-and-go got up and went." If your vehicle's engine's fuel economy is noticeably worse, your engine is idling roughly or stalling or your vehicle's acceleration isn't what it used to be, ask your service advisor if you might need your vehicle's fuel and air induction systems cleaned. As the hours pile up on your engine, carbon deposits can build up.  It's not unusual for some of the impurities and additives in fuel to leave behind a black residue that eventually will negatively affect your fuel economy and performance. Maybe you're noticing your engine is harder to start, you hear knocking or pinging in your engine and your vehicle just doesn't have the pep it used to. While it's a sophisticated process with a lot of components, a gasoline engine essentially produces power by drawing in air from the outside and mixing it with fuel in the cylinders where this blend of fuel and air is ignited by spark plugs in synchronized explosions.

If you're like most people and drive a gasoline-powered vehicle, you need to be up to speed on its fuel-related components.  They're pretty basic: the fuel, the fuel filter and the fuel pump. The fuel's the easy part.  You probably gas up your vehicle yourself and, if you're like most drivers, price is a big factor in what you put in your vehicle. Maybe you think it doesn't matter what kind of gasoline you buy, but one major automobile association has found it does make a big difference.  Their study showed that the additives that are put in different brands can affect your vehicle's performance.  Certain gasoline retailers sell gasoline that meets performance standards called Top Tier.  The detergents used in Top Tier gasoline help protect newer engines from carbon buildup and deposits on intake valves, all things that can affect how smoothly your engine runs, how it accelerates and what kind of fuel economy you get.  You can check online or ask your serv ... read more

With the weather getting colder, you might be tempted to start your vehicle up, let it idle for 15 or 20 minutes and then get in the nice, cozy cabin.  Some vehicles offer remote starting that let you do that from the comfort of your home or apartment.  But is letting your vehicle idle like that good for it? Manufacturers say it doesn't harm the vehicle.  They say it's because modern vehicles are made differently from those in the past.  Just about all newer vehicles employ fuel injection which uses computers to adjust the amount of gasoline that goes into the cylinders.  The engine gets only the fuel it needs, taking conditions into account. Older vehicles, on the other hand, used to use carburetors.  When you started a cold engine, the carburetor wasn't able to adjust the gasoline amount depending on conditions.  Some of the gasoline would mix with oil and the pistons wouldn't get the same lubrication as they would with undiluted oil. So yes, you ca ... read more

With San Diego gas prices being what they are, many of us in CA are driving less and looking into purchasing smaller or more efficient vehicles. San Diego area residents who have to drive a lot, have large families or need four-wheel drive are particularly hard hit by the cost of fuel in CA. But there are things all San Diego drivers can do to save fuel: We can improve our driving habits and stay on top of preventive maintenance at John's Automotive Care. These things make small savings possible, but they can really add up.Let's start with driving habits. One major gas-eater is jackrabbit starts. A smooth, gradual acceleration uses a lot less fuel. It's also easier on your engine and drivetrain, so you'll prolong their lives as well.If you drive with one foot on the brake, stop. That creates drag, increasing fuel usage and reducing the useful life of your brakes.Slowing down can really add up on gas savings over time for San Diego drivers. Driving five ... read more

Have you ever thought about all the little things we do to keep our lives running smoothly - like vacuuming? It makes a room feel fresher and more comfortable. We may not consider that we're also prolonging the life of the carpet by keeping it clean. But San Diego drivers don't always extend those good habits into the garage. Our vehicles need regular maintenance just like our rugs need vacuuming. We may not notice a difference in the feel or appearance of the vehicle, but just as cleaning a carpet carries the hidden reward of prolonging its life, maintaining our vehicles incurs a hidden reward that becomes noticeable at San Diego gas stations.When it comes to reduced fuel economy, there are two culprits: increased friction and inefficient fuel combustion. That means that anything San Diego drivers can do to decrease friction and increase the efficiency of their engines will translate to savings on fuel. Friction increases the amount of energy it takes to move something. So if we can r ... read more

Most San Diego drivers are all talking right now. Better gas mileage. Fewer emissions. CA folks want to save the environment and our pocketbooks.And we San Diego drivers all know — or should know — that preventive maintenance will help maintain maximum fuel efficiency. But is there something more we can do? After all, some of us San Diego road warriors can't cut back on our driving, and others would like to do more to economize.Weight is one major enemy of fuel economy. The more you lug around in your vehicle, the more fuel you have to burn to get around San Diego. And that means buying more gas and producing more emissions.Of course, your vehicle's weight isn't negotiable. And you can't do much about the weight of your passengers. And this isn't an article about diet and exercise.But look around your car. Are you hauling a bunch of unnecessary weight while driving around San Diego? Do you really need your golf clubs every time yo ... read more

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
