Don: I am a great believer in diesel service motor oils. Thay have served me well over the years. In the mid 1970 I was running 6 Farmalls, 1 Deere, 2 Case, 4 Chevy trucks, 1 MF combine, 1 car and a 4 cycle lawn mower. I was using 3 grades of oil and had about 6 employees. I discovered employees were not keeping it straight on which oil went where. To cure that problem I became a one type motor oil guy. Looking at where the dollar value in engine was the oil became diesel service. Initially I went with 20 in winter and 30 in summer. I later switched to 15W-40 year around. I have had exceptional results; never rebuilt a diesel under 10,000 hours, GM gas engines have gone 300,000 Km. for me,no exceptions, got a 6.2 Chevy deisel to 650,000 Km. I still have that same 4 cycle lawn mower. I use it in my Super A, 130 and 140 today, wouldn't think of changing to any other grade. I have a Buick here with 3.8 engine, 450,000 Km. The Buick is coming up for emission testing, I think it will pass, it did two years ago with no tune ups.
