I will let someone else test that. I just ordered a few more cases of 10W-30 SJ oil with zinc. It is funny how oil not specified for automotive use doesn't have to meet all the EPA regs and can have more zinc in it. I have had customers ask if i use the latest rated super synthetic (expensive) oil. No, i use a cheaper oil that works better.
