You know something guys' everyone is traditionally stumped on oils- engine gear cases etc. Well think about it , the chain case is that a chain case, it does not see 200 degree temps.as an engine. It only requires quality oil for lube, not 75-120 or anything else heavy like for heavy equip. They sell chain case oil buy the barrel that's labelled meaning that an oil of a light grade or synthetic will work you don't want heavy oils in the case. Best oil I have used is trans fluid, it's very fluid in extreme below temps., it's compatible for extreme loads etc. But in all it's what you want to use at your choice dealers and parts places love us right?
