I have seen only 2 UOAs for this oil, and they seem to be good...apart from people who did uoa's, are there any others who used this oil in a gas engine? What were your impressions? (cold starts etc.)local Wal-marts always seem to carry this oil, both in 4 qt jugs and 1 qt bottles, I think. I'm trying to decide on a good/priceworthy 5w/40 oil...are there any DINO 5w/40 oils?(could be a stupid questions for some:-) Thanks.
