i try to stay away from oils with such a large span in viscosity such as 20w50 because they have to use so many polymers to "fill the gap" and that sort of leads to thermal break down and an oil with the least polymers is happier engine.
now im all confused, what oil should i be running?
We could turn this into a poll but my money is on 20W-50 winning.
