Hey guys check this out. u wont ever have to add oil agin. jusst add vegetable oil an it works just the same! i do it every time and have had absolutely no problems. and that got me thinkn of an even better idea: take some cooking spray and spray a nice even coat on the top of ur engine, using about one-half of the bottle. it will kinda sink in through the metal and will give even better protection than any other engine oil out there. and the best part is its cheap as hell. ive had absolutely no problems whatsoever. ill spread the word around for u guys.
