i will NOT put down any oil that i dont use. but i use marvel mystery oil , have been for all most a year, no trouble. wallmart has the 16 oz and the 32 oz size, in the automotive section. side note, i also use it in my street truck gasoline, have been for 3 decades. runs smother starts VERY VERY fast. it lubes the valves, and the piston rings. look for "ampo top cylinder lube" they have a lube machine a lot like the old mmo inverse olier
