Genny oil

With no catalytic converter to clog up, a generator is a good candidate for four stroke motorcycle oil with zinc. Amsoil sells several different oils that have zinc in them, and also sells a "small engine oil" designed for such things as generators, lawnmowers and such. Zinc is an excellent "lubricant" additive for oils, but it cannot be used in autos and trucks now due to the converters. In the past, it was found in almost all motor oils.
