You may have observed while driving on the highway that the oil level warning lights on the dashboard suddenly begin to glow. You pull over to the next car repair center near me to get some motor oil. You’re looking at the different engine oil selections on the shelf and aren’t sure which one to choose. What blood is to a human being, engine oil is to a car. Any car, it is safe to say, cannot function without engine oil. It protects automotive components from wear and strain even when temperatures within the engine reach 120 degrees.
