..... Same results for flat tappet break in.
I do not have test results to back this up, but GM discontinued EOS a few years ago because the additives in it would damage the cats before the warranty period expired.
At that point, the word I received from a source at Comp Cams, they acquired the original formula from GM and it is now labeled for them.
Over a year ago, GM offered EOS again, of course at double the old price.
So ZDDP is over twice the strength, amount of additives, of the old EOS, so where the current EOS is stands now in quality and performance is questionable?
I don't think GM has any engines with flat tappet cam still under warranty, so why would their product be even good for our old tech engines?
Another point, as far as I can find, NO ONE but ZDDP has actually published test results and details of their product?
They either will not tell you [or me], or they do not know.
With ~$ 20K invested in my engine and turbo I want to know what is protecting it. None of the advertised oil additives are as inexpensive as ZDDP, and all of them are unknown, except for their brand name.
Sorry, I do not accept or trust the ad companies "claims and TV demonstrations" to protect my parts.
Just my opinions!
