I want to talk a little about fuel economy, the simple things you can check and do. All the little things can add up, especially now that gas prices are starting to rise. Maintaining your vehicles will make them more efficient. When your car is well maintained and works the way it is designed to, that means it uses less fuel; that means you save money.
There are two main issues that rob you of fuel economy. One is increased friction and the other is inefficient fuel combustion.
Friction! Anything that increases friction increases drag or load on your car engine. Your engine has to work harder to overcome that drag. In return you use more fuel.
One of the first things that come to mind is engine oil. Low oil means that there is not enough to fully lubricate the engine to reduce friction. The wrong oil viscosity and grade of oil can also adversely affect your fuel economy. Dirty engine oil does not lubricate as well as clean motor engine oil. The same applies to your transmission fluid. Getting your oil and transmission fluid serviced at proper intervals will help reduce friction to save fuel, and help make your engine and transmission last longer. You can also consider upgrading to synthetic oil and transmission fluids, and on rear wheel drive cars synthetic differential fluid. Synthetic fluids cost a little more, but help by reducing friction and help you save you fuel.
Another very important friction that is over looked is UNDER-INFLATED tires. When car tires are low, it’s like driving through sand. When driving on low tires, it makes your engine work much harder every mile. So please check or have your tires checked at least once a month.
Sticking or binding brakes can put a drag on your car, without your knowing it. A simple brake inspection twice a year by a qualified technician, should be considered.
I want to talk about fuel. A dirty fuel system has gum and varnish interfering with the fuel injectors ability to deliver the correct amount fuel at the correct pressure and in the spray pattern the engineers intended. A professional fuel system cleaning can get everything back to factory specs, and improve your fuel economy.
Replacing worn ignition parts, like spark plugs will burn fuel more efficiently, and will save you money at the gas pump.
