in my opinion, this is by far the best non-snythetic oil ive ever used
most of my bogging issues are gone now
out off all the times ive changed oil in any car, i have never seen this big of a difference in performance
the only thing that would make me happier is synthetic, but i refuse to put sythethic oil in a 13 year old engine(i dont want to risk burning oil)
i also topped it off with a new sure drain, drain plug. Thats another good product, you never have to worry about stripping the oil pan
overall a good experience for me
