I get this a lot from some of the f-body guys I talk with on the internet, they seem to think that the 20w50 and 15w50 oils out there will offer better engine protection for them, as they seem to think that thicker oil means longer life.
I usually tell them that thicker isn't always better and if the engine wasn't designed with the thicker oil in mind (looser clearances) and the oil pump and oil passages weren't designed this way, then you could end up doing more harm than good.
Comments?
