I was reading into "bob the oil guy" and just want to make sure the motor is protected even on start up. The first flush before I pull her out for winter will be the 0w-30, and I will let people know how that turns out, and if it does not, back to 5w-30. Gotta love the cold winters in Utah.

On the gear oil, does anyone know the pros and cons there for 90 vs. 140?
