Here's why:
* Different Formulas: Diesel engine oil is formulated to handle the higher temperatures and different combustion process of a diesel engine. It has different properties than gasoline engine oil, such as a higher viscosity and different additives.
* Lubrication Issues: Using diesel oil in a gasoline engine can lead to poor lubrication, causing engine wear and damage. The oil may not be able to adequately protect engine parts designed for gasoline oil.
* Seal Compatibility: The seals in a gasoline engine are designed for the specific properties of gasoline engine oil. Diesel oil can cause seals to swell and leak, leading to oil leaks and other problems.
Always use the type of motor oil recommended by your car's manufacturer. The information is typically found in the owner's manual or on the oil cap.
If you're unsure about the correct oil for your car, consult a qualified mechanic or your car dealership.
