valvoline is a pretty good oil, and it doesnt have a residue,its pennsoil that leaves a build up, because it has penzaine in it, i ran valvoline for 6 years in my 5.3 and when i tore it down it looked clean as a whistle, so i say go for it. i now have a built 6.0 and run moble 1 cause its high performance and on spray
