Edition and it says the same thing in the owner's manual about using diesel engine oil if HD isn't available. But like I said, I'm not a mechanic and I learned a long time ago that it's better to keep one's mouth shut and appear a fool than to start talking and confirm it. I use AeroShell 10W50 in my C75. AeroShell costs 9.05 including tax per quart at the FBO here. I checked the price on a case at Wag Aero and with shipping it's about $7.50 per quart. Where do you buy yours?
