Motor Parts !

Twenty-first century motor oils offer different grades and brands. Though they may appear (or even feel) similar, they are not the same on the inside. Mineral-based motor oils have been refined (though they still originate from the earth); synthetic motor oils are completely manmade using a base of mineral oils; and semi-synthetic (premium) motor oils are a mixture of the former two types.

Motor oils typically contain additives such as detergents, buffers and other ingredients which keep the engine primed and ready for action. (Note: There is a type of motor oil known as a "pure" synthetic; this is generally used in industrial machinery and is therefore beyond the scope of this article.)

Which Motor Oil to Choose

Motor oil comes in a variety of grades, each offering a unique trait. Some offer amazing fuel economy, others boast incredible performance. Other motor oil "selling points" include quick engine circulation (even in very cold temperatures), high mileage vehicle protection, and deposit/build-up defense. The savvy motorist must pick the most needed characteristic for his or her vehicle.
