Keep your engine clean and running with high-quality motor oil

Motor oil is just as important as gas in ensuring your vehicle is working properly. Without it, you risk ruining your engine beyond repair. For brand new cars it is recommended you use a full synthetic oil. This is made from derivatives rather than all-natural oil and provides the best lubricant for a new car engine. For older car models or used cars where you don’t know the car’s maintenance history, a synthetic blend is best. Here are several of the best motor oils including those for motors other than automotive.
