This one does not advertise zinc. I would question what wear protection value it really has. Since is low or no zinc, it’s probally exhuast system safe.

This one can be found at large franchise auto parts and auto supply stores

I’ve been inside several of my own engines that have in excess of 250,000 miles, one gas and one diesel, both were spotless inside. Appropriate oil changes are all that is required to keep the internals clean. Heck, the gas one still had the original crosshatching on the cylinder walls to boot.

Any good oil doesn't need additives. If you think you need it then you might want to switch to a better oil.

Or engines under extended oil drains since the zinc and phosphorous in the old stock version will recharge the oil with zinc and phosphorous.

For the new version of this product the recharge benefit would be questionable.

Any independent empirical evidence to support the claims of these additive makers? I just remember the debacle of Slick50 and how NASA debunked their claims.

Buy the best oil that meets the manufacture's specifications. Change according to manufacture's recommendation using a quality filter. Leave the additives on the retailer's shelf.
