New or used? Based on location I would say a 10w30....someother questions to consider is do you have an oil filter on it? Some of the older engines ran on 30ND (ND meaning non-detergent) If that is it case and you put a high detergent oil in it you can expect it to cut loose some crud that may cause some major problems. If it is new and has an oil filter I would probably use 10W30HD(HD meaning High Detergent)It does have inserts in the rods doesn't it?? I'm sure some more will add there comments later. This is just my opinions.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
