Re: New zinc additive for oil in older engines
Typical marketing hype goes something like "exceeds API specs". Okay, if so, by how much in each of the numerous API tests and by how much will that extend the life of a typical engine.
I don't think anyone here has the resources to run all the required tests, and I know of no independent/disinterested third party sources that have conducted tests that definitively prove that one CJ-4 oil is better than another, but if anyone has such data...
Regarding gasoline I have a friend who insists on Top Tier gas. I've always used Arco because it's cheaper, but recently Arco joined the Top Tier ranks.
My friend still refuses to use it.
