[AT] Synthetic Oil

[Cecil Bearden]

I really don't know.   The 5w-30 is labeled as engine oil, and the 15-40 
or 15-50 is labeled as diesel engine oil.  This was the reason I only 
had one diesel with the 5w-30 to start with.  They are light loaded now 
as one is used as a  utility tractor with a loader used for moving hay 
and bale spike and the other one has a pintle ring on the loader for 
spotting trailers and a Post hole digger on the back..
