Wasteful Thinking

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

Will Proper Auto Maintenance at John's Automotive Care Really Save Gas?

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

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.

Do you really need your golf clubs every time yo ... read more

Good Service at John's Automotive Care Equals Good Fuel Economy in San Diego

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
