Any oil that the EPA hasn't sucked the Zinc or ZDDP out of. Most are required to say for off road use only. The Zinc or ZDDP is what lubricates the tappet to cam. Have never heard of camshafts breaking much until a year or two after the EPA quietly made manufactures remove the zinc for better emissions. Then all of the sudden 5 people I know had cam failure within 6 months.
