What's your opinion of using ZMAX in a 365. I saw the adds on SPEED and thought it might be worth trying. I've never used oil additives but now that the automotive police are mandating the removal of zinc, I'm going to add 8 oz. of ZDDP to help reduce primary wear. I've been looking for this fix that Bill Muno, Central States, published in The Prancing Horse. The ZMAX appears to have good wear properties. I considered adding it along with the ZDDP unless there is a good reason not to. Thanks for any input.
