anyone tried rotella t synthetic oil[5-40] in a 5.0? have been using
mobil 1 10-30. might be a little thick when warm? ive been told not
to go w/ that thick of oil in the mod motors. what about the windsors.
my dad has a 99 escort that he runs it in and loves it. it has 259xxx on it and runs like a top. i have a 87 tbird with a slighly modded 5.0 with 222xxx on it and i run the shell 10w 30 syntetic blend (silver jug). runs great, lifters are quiet and it dont use much. i like the stuff
