For those of you who have been around this board for awhile and those of you who have just done a lot of reasearch, which oils have you found to be formulated at the minimum level possible to meet SL/GF-3/A3B3 (not necessarily all inclusively) and which seem "fortified" to truly exceed specs. For Amsoil and Redline, if, in your opinion, they exceed minimum requirements even if they haven't been formally submitted to API or whatever, please include them. Please break out by grade if you think a company's XW30 is strong but their XXW40 is weak. I think making a list like this (if it doesn't open a Pandora's box), will help our members, especially new ones to find the dino or synthetic that gives them confidence really easily. Thanks.
