This has to be the best oil I ever used. I noticed the difference as soon as I put the oil in and started the engine.! I will continue to use this oil for as long as I own, the vehicle and any future cars I may own or drive! I read 75% of the reviews before purchasing this oil . The only thing I’ve noticed. Anyone who gave it below a five star was because they received used motor oil.. in my opinion I think it was returned after somebody filled it up with their used motor oil and returning it for their money back somehow Amazon put it back on the shelf for resale. So take it for what it’s worth but it’s really great oil.
