I was talking to a non Porsche engine building /machine shop yesterday and he told me new oil formulation regulations means we need to add zinc additive in older cars
Any one out there have knowledge ( versus opinion) on this. I use Brad Penn but he seemed to indicate this is industry wide. He was not trying to sell me anything |

everything you ever wanted to know - here Ultimate Motor Oil Thread or Why we hate CJ4/SM oils http://forums.pelicanparts.com/porsche-911...j4-sm-oils.html - suggest you start at the latest (last) posts & work back we don't need to reinvent this discussion (IMG:style_emoticons/default/piratenanner.gif) Didn't read all 105 pages of that thread (IMG:style_emoticons/default/blink.gif) But I've read a fair amount about the ZDDP issue and I'm curious what you smart guys think about these posts suggesting the ZDDP thing may be overblown: http://pedrosboard.com/read.php?7,30533,30536 http://www.nonlintec.com/sprite/oil_myths.pdf http://www.chevelles.com/forums/13-perform...-more-oils.html I don't know what to think. I see a lot of discussion on many forums about the importance of ZDDP for classic engines, but very little hard data. And I'd like to know more about whether newer anti-wear additives like molybdenum and titanium compensate for reduced ZDDP. It's a confusing topic for a simple consumer. |
