You could simply purchase the most affordable oil that you can find for your car, but this decision could actually cost you more money in the long run. Certain cars need certain types of oil, and the oil that is best for a car may change with time. For example, a car with high miles might need different oil than a car with lower miles. The type of oil you choose for your car will affect how many repairs your car will need and long it will last before it is destined for the junkyard.

The Right Viscosity for Your Engine and Climate

The first step is to open up your owner's manual. It is important to purchase oil that has the right viscosity, or resistance to flow. The manual will contain the right viscosity information in the form of a number such as 10W-30. The recommended oil might also be placed on the oil cap on the engine as well. The number determines the extent to which the oil thickens in the cold. It is necessary to select oil that is right for your climate to make sure that the oil does not thin too much. The first number determines the thickness of the oil at a low temperature while the second number determines the thickness of the oil at high temperatures.

The Highest Manufacturer Standards

The oil should meet the highest manufacturer standards. If the oil comes with the American Petroleum Institute certification, the container that stores the oil will come with a starburst logo. This will indicate that the oil has met the highest oil-performance standards.

The Right Additives

Better oils come with additives that help protect your car's engine from corrosion, can better cool your engine, and can also help keep it clean. Anti-corrosion oils are especially important if your vehicle will remain idle for a long period. Normally, oils coat the interior components of the engine to protect them from rusting, but the oil slowly drains from these components when the car remains idle. 

Synthetic Might Be Superior

Synthetic oils are an alternative to traditional oils. The belief is that they will allow for more time to pass before you need an oil change, but this has yet to be proven. But if you are unsure of whether you should add synthetic oil or any other oil type, it is best to contact an automotive technician for assistance.
