After adding oil, I noticed the ticking noise from the engine was barely noticeable and it began running smoothly within 15 minutes.
After putting Marvel Mystery Oil in the oil and the tank in the morning before my commute, the engine was running smoothly by the time I reached work 37 miles in traffic.

92% highlighted the oil filter compatibility
This product has helped me keep my Toyota and BMW running smoothly and like brand new.
I replaced the fuel filter but the engine was still running rough. I decided to try Marvel Mystery Oil and put it in the oil and gas. After driving 37 miles in traffic, the engine was running smoothly.
