Well, not except during takeoff and climb. Maybe I should try it, the Airplane Flight Manual says it's ok.
Reminds me of when I got my first Super Cub. I asked a grizzly old Alaska bush pilot how he ran his Cub. His answer was, "Give it full throttle for takeoff and every once in awhile reach over and tap on it to make sure it hasn't "slip back" any"! Funny thing but he always got full TBO out of his engines.

Northern Tool here in the DFW area must be dumping their MMO on the market this month...it usually sells for about $7 to $9 for a pint ...but I just bought a gallon of it from them for $11.
Too bad I don't have a use for it.

Put it in your tractor or on your salad, I like the light wintergreen flavor, goes well with fresh greens.
