Jim, I have the original specs page up on the web on my website (link below) that will help for most of the fluid capacities and so forth. I use 30w Havoline in mine here in SC, also figure 10w30 would be good here (probably have to since I hear 30w Havoline is on the way out with the recnt merger to Shell). Your climate will go a long way in determining what grade you use.
