Rem18 Posted April 19, 2018 Report Share Posted April 19, 2018 (edited) So due to some difficulties on the road a long while back I bought some modern Castrol Gtx and put it in the 5... Forgot about it for a couple of years and and got a few wry looks regards the lack of Zinc and stuff. Well just putting some Castrol Classic in now but as I started I thought I would do some research. So Take a look here a very nicely done table of research and it seems to be saying that Zinc and stuff is no big deal after all. Modern Castrol GTx 20/50 comes out really well......... http://www.chevelles.com/forums/13-performance/443674-zinc-myth-test-data-dozen-more-oils.html Maybe we should stop worrying about zinc and start looking at the research. The guy actually states that the Zinc thing is a popular myth..... Tony Edited April 19, 2018 by Rem18 Quote Link to post Share on other sites
