There are many ways to improve the fuel economy of your car while driving steadily and no sudden accelerations to inflating your car at the right pressure. You should also know that car engine oil also contributes as a major factor in helping your car reach the extra mile with no extra costs.

Normally, mineral oil is the regular oil that lubricates your engine, but requires frequent changing. Semi-synthetic have minute polymers inside them that reduce engine deterioration as well as help protect the engine from cold damage and cold-starts. Fully-synthetic oil enhances performance of the engine by reducing carbon build-up and has excellent, ability to avoid cold-starts.

To choose the right oil for yourself, you should always look at the car's engine manual for recommended oil and make. Aside from that, your car mechanic will also suggest you the very best oil based on the car and the conditions you drive in.

For most buyers, the fully-synthetic one is the very best since it proves economical in the long run and does not require changing as frequently as the mineral oils do. Since these are manufactured in specialized labs by adding additives to the basic oil, they are able to provide performance, engine longevity and better efficiency.

Thicker or thinner oil is what matters most. The lower viscosity oils work best and should be used in your car. Oils that are thinner work the very best in cold conditions and turn thick when conditions become warmer. You can also go for multi-grade oils that have extra polymers in them that activate only when the oil gets heated up, unless they keep the oil thin.

First you need to ask yourself some questions: What's your dream ride? What models do you like best? How old should it be, and the amount of miles should it have? Just how much are you going to spend? By answering these questions, you'll have a better idea of what you really want and what you agree to go for. If you know this before you walk into a dealership you'll have a much easier time negotiating a large amount on the car you want.
