Hey folks - seeing all sorts of conflicting info on the proper oil to use for the 3ym20 engine. A lot of folks recommend Rotella, some recommend the yanmar oil.
However, the only Rotella and Yanmar oil i can find in 10w-40 both reference API ratings of CG-4 and CH-4. The service manual specifically states NOT to use CG-4 or CH-4.
Anybody use an oil that's CD better, but NOT CG-4, CH-4?
Thanks much - Dave -Tampa
