I appreciate the combined knowledge here Gentlemen! I have a new MF 492 with a 1104C-44t Perkins. I sure hope this expensive tractor will last longer than I do - and I'm 42
. What oil do you guys suggest - considering the investment,the cost of "better" oil is immaterial. The manual suggests 10-30 or 15-40 CIL-4 for my mostly warm west Tn weather. The tractor has 10 hours at this point - when can i change to a high grade synthetic? Thanks for the answers!
