Q: WHAT DOES MOTOR OIL ACTUALLY DO?
A: Motor oil lubricates all the moving parts in the engine. This prevents any friction that would happen if motor oil wasn't in your car. Without motor oil, engine parts would grind against each other and cause wear and tear on the components. The longer you go without an oil change, the thicker the oil gets. This is because the oil collects contaminants, metal fragments and grime as it goes through the engine block.
If you allow your oil to get sludgy, buildup will occur around crankshafts, valves and pistons. The longer this persists, the more likely you are to experience damage that may require expensive engine repairs. In some cases, engine parts will no longer usable and you will need to be replace them completely.
Expensive engine repairs can be avoided by changing the oil in your Buick and GMC regularly. When you get new oil, it is contaminant-free and improves the performance of your Buick and GMC vehicle. It also extends the life of your engine, increases your MPG and decreases the harmful emissions from your car.
