Sea Foam Motor Treatment or High Mileage in engine oil will not effect viscosity. I’d recommend using the “thinnest” engine oil that the generator manufacturer recommends based on ambient temp. Sea Foam Motor Treatment or High Mileage in engine oil will help clean any residual gum or varnish residues from the engine crankcase and oil galley areas and help the engine oil flow better and stay cleaner for the life of the oil and filter.
