Before the oil tread gets dumped again, I would like to point out something that I discovered.
The oil recommendations in the Owners Manual and the Work Shop Manual donot match. The Work Shop Manual does call for the thicker oil like 20W50 with temps. above 14 degrees F. I prefer the 20W50 for the climate that I reside in, but it will ultimately be your decision to make.
Sitting back and taking the credit,
