Hi All... I currently service my C-85 12-f with AeroShell W-80 and W-100 oil.
I would like to go to a sythetic based oil because of the cold weather. My question is what would be the best oil for start at -10C and what proceedure would I have do to perform the change (IE drain, flush, fill, change filter or other)? I preheat my Coupe but I have heard that the new synthetics are better for starting, and all seasons use. The motor has apprx 300hrs SMOH. Also The cylynders have been chromed at time of OH. Regards R A "Bob" Pionteck CF-LAV
