I recently switched my 1960's Deere payloader over to Sunoco ATF in its Allison trans and loader hydraulic systems (yes it meets the specs AND it gives me much better cold weather performance) and now I'm looking closely at Sunoco Super C 15w-40 as a single oil for my 3 tractors, two Cummins pick-ups, and previously mentioned pay loader. The specs looks good to my eye...
