I ran into a friend of mine who ownes another shop close to ours at the auto parts store buying 5 quarts of 20w50 he uses in his 97 chevy tahoe when i noticed it was 20w50 i told him figuring he is an older man in his seventies and he picked up the wrong viscosity but he said to me he has used it since the truck was about a year old and it runs great! And then said thicker oil is so much better than the thin as water stuff.. I realized there was no convincing him otherwise so i walked out to his truck wanting to hear the engine and when he started it i could barely hear the engine it ran great with 122,000 miles on it.
Like i said they are a busy shop and from what i can see does nice work but then this?? He also changes his oil every 2500 miles.
I could not believe it this guy has a busy shop and does just about everything and he was using 20w50 in an engine that requires 5w30
