I do not use anything but outboard boat motor oil and have "never" had a problem. Been mixing for Maytags for 25 years with outboard boat motor lubes of various brands. What problems have you experienced?.i mix 16 to 1 for my maytag with non deturgant straight 30 oil.i found outboard motor oil or 2cycl oil doesnt work as wellin the old engines.
Andrew,Now days, especially with the crappy E-10 alcoholized gas, our engines need all the lube they can get. The SAE 30 has a heavier body than the premix lubes out there, and provides a better crank seal.
