i amazes how people cant follow manufacturer recomendations. thick oil is not good. it takes a lot longer to reach the top of the engine and that means when u start, its running dry up there longer, take longer to get to all the little crevis'. it also makes fuel economy worse
10W-30 is what this motor needs. 5W-30 is only better when u live far north since 10-30 is good to 0 degrees F yes F. water freezes at 32 degrees F.
10W-30 is good up to well past 100 degrees F so this covers almost all of us.
