Can You Use Diesel Engine Oil in a Petrol Car?
Can you use it?
Sometimes. A bottle labelled for diesel engines is suitable for a petrol car only if it also meets the oil specification and viscosity required for that car’s engine. The diesel label alone does not establish compatibility.
What should you check?
Compare the requirements in the vehicle manual with the approvals and viscosity printed on the oil container. The information supplied here does not identify a particular car, engine or oil, so it cannot establish whether a specific product is suitable.
If you have already added oil and cannot confirm that it meets the car’s requirements, ask a qualified mechanic to check it and advise whether an oil change is needed.
