When I started out in motor oil I used to be a thin guy and thought thin would be the best for Canadian cold starts.
Then I started researching euro spec oils and thought HTHS was the best measure of engine protection combined with an additive package capable of extended OCIs.
More recently I've been learning about base stocks and viscosity improves, as well as re-visiting the Motor Oil University, which is bringing me back to the thin side. So I switched sides twice on the thick vs. thin debate.
