[AT] Engine oil

[Doug Tallman]

I would say the problem is the synthetic oil. It is too slick for some 
engines. A buddy bought a fairly new motorhome with the GM 8.1. Since he 
wanted it to last he changed to synthetic oil. First trip out they 
coated the tow car with oil coming out the back. Dang the rotten luck, 
pulled the trans and replaced the rear main. No other signs of leaks. 
Next trip it was the same thing. With some research he found that GM 
recommended not using synthetic. Changed back to regular oil and problem 
solved.  Doug T
