Hello,
I've just purchased a 5665 model Gravely walk-behind tractor, 1984 year. 12 hp Kohler K 301 S engine, single cylinder gas.
I would like advice on the best oil to use. No oil filter on this older engine. Air cooled.
Original manual says 30W above freezing, 10-30 below freezing, and an SG or SH classification, which are now obsolete.
Should I stay with those weights? I will change religiously at 25 hours maximum.
Any advice on the best brand, whether regular or synthetic, etc.
Thank you so much for your help, Peter
