What is the preferred oil WEIGHT for the U20? I ran 5W-30 through the
colder months and have been running 10W-40 this summer. The oil pressure
drops quite a bit after the motor's warm. Would 20-50 help maintain higher
pressure, especially around idle? I'm changing oil this afternoon, so this
couldn't have come at a better time!
Thanks
Nathan
