Engine Oil 101: The Basics of Engine Oil

It takes fuel to make an engine run, but it also takes oil to keep it alive. As we all try to maximize the service lives and fuel economy of our engines, it’s important to understand engine oil’s role in all this, whether you use conventional, semi-synthetic or synthetic varieties. This is an amazingly complex subject, so I am going to share some basic information to get you started. I won’t get into every last detail here, but I will arm you with the fundamentals.

Base Oil

There are two main components that any motor oil is made of. There is a base fluid (sometimes called a base stock) and the additive package. The base fluid typically makes up the bulk of the oil. Additive chemicals are then added to enhance the positive qualities of the base stock and to overcome whatever negative qualities there may be.

What are the Requirements of Engine Oil?

Motor oil must create a film between moving parts to make them "slippery" which increases power, performance and efficiency. The film that motor oil provides between metal surfaces does more than just lubricate though. By keeping engine components from coming in contact with each other, motor oil also provides protection against wear.

Motor oil must also protect against corrosion of engine components. Oxidation of the oil and contamination from condensation and combustion by-products which cause acids within engine oil. Additives in engine oil are designed to combat these acids

So, there you go guys. Engine oil 101. Now you are expert in engine oil and can choose the right oil for your car.

Have a nice day guys and remember to always drive safely!
