That might be a pretty abrupt shift at 3100 RPMs though - and on a cold tranny too. I just let the '90 stay in 2nd and run at lower RPMs until it shifts when it decides to (about .5 mile).

The heat within your engine is primarily generated by the combustion process, not internal friction. So the weight of oil you run should not have any real impact.
