Pakrat 1,043 Report post Posted May 7, 2009 Here's just a few threads on the subject, I'm sure there are many others but the search engine won't accept just a 3 letter word like oil so I had to search for a specific brand and hope for the best: http://www.1969stang.com/mustang/forum/search.php?searchid=223993 Quote Share this post Link to post Share on other sites

jag 10 Report post Posted May 8, 2009 I was just down this road and trying to read up on it. If you agree the older engines need more of the anti wear additives then you have to look at the phosphorous content, not the zinc. ( That is what the articles said) The articles I said Mobil 1 15w-50 was good for racing and flat tappet engines. Valvoline VR-1 Racing oils 10w-30 & 20 W-50 were good. It also stated diesel oils that were rated for diesel an gas engines had plenty of phosphorous and zinc in them. You could run them also. If I remember the limits were minimum 1000 ppm for the phosphorous. I am running the Valvoline VR-1. I have just started it though JAG Quote Share this post Link to post Share on other sites
