i just did an oil change using 0W20 M1EP SN. i sniffed a brand new 5qt jug and was surprised by this strong and a bit pleasant aroma. I vaguely recall smelling something similar in Pennzoil oil a while back (or was it Valvoline? forgot which one). I still had some empty bottles of the 5W20 M1EP SM oil i used previously and they didn't have that smell. Is this a sign of esters?
thanks!
and to preempt jokes about tasting, i haven't done it.
