Re: Zinc levels in oil
Mark, I'll add that to my list. Where did you get the specs? I tried their website, but couldn't find a spec sheet. What about the content for 15W40, 30W, and 40W?

Re: Zinc levels in oil
Marty, Outside of what Mark said, there basically isn't. The article that raised the warning in Hot Rod Magazine is the best source, but it only covers Quaker State synthetic racing oil, Pennzoil Racing Oil, and Shell Rotella. You can go to the individual oil company website and look up the oil and read the spec sheet, but sometimes the zinc and phosphorous content isn't listed. For Kendall oils, the zinc was listed. For Pennzoil Racing Oil, is wasn't listed. You just have to search and read. Directly from the Hot Rod article, June 2006, When Good Cams Go Bad: SH API oil rating 1996 zinc = 0.130%, 1130ppm (parts per million) phosphorous = 0.120%, 1120ppm SJ API oil rating 2001 SL API oil rating 2004 zinc = 0.110%, 1100ppm phosphorous = 0.100%, 1000ppm SM API oil rating 2005 zinc = 0.087%, 870ppm phosphorous = 0.080%, 800ppm Cosworth Racing Oil zinc = 0.125%, 1250ppm phosphorous = 0.115%, 1150ppm Shell Rotella T zinc = 0.140%, 1400ppm phosphorous = 0.130%, 1300ppm Pennzoil 25W-50 Racing Oil zinc = 0.196%, 1960ppm phosphorous = 0.180%, 1800ppm Quaker State Q Racing Synthetic zinc = 0.200%, 2000ppm phosphorous = 0.180%, 1800ppm Obviously, the 4 oils above do not have an API rating for newer engines. Their rating would be SH or SG. Pennzoil Racing is SG. Rotella is SH/SJ. From the Kendall website for GT-1, which I've used since 1964 and now can no longer use for fear of cam and lifter damage: Kendall GT-1 amber 40W. Older green GT-1 was used in Thunder and still have 5 quarts of the green oil left. New GT-1 color is amber. Green GT-1 has high zinc and phosphorous content. Amber GT-1 has low content. zinc = 0.104%, 1040ppm Kendal GT-1 amber 30W. Older green GT-1 was used in the other Olds engines. zinc = 0.104%, 1040ppm Kendal GT-1 amber 20W-50 zinc = 0.113%, 1130ppm Kendal GT-1 amber 10W-40 zinc = 0.086%, 860ppm Marty, that's where our engine oil for our older engines has gone, to-Hell-in-a-handbasket. You'll have to search out the rest of the info for other brands on your own.

Re: Zinc levels in oil
Mark, Can you come up with specs for Chevron Delo showing the zinc and phosphorous content?

Comp Cams says to run shell Rotella in our older engines to get enough zinc and phosphorous. Get the June issue of Hot Rod and keep that article. Rotella puts the zinc level up to 1400ppm. Since the EPA is going to bitch at the OEM Diesel mfgs to require cats on Diesels, the zinc and phosphorous will get cut in Rotella. I'm going with Pennzoil Racing Oil at 1960ppm zinc. Chevron Delo claims that they're keeping their diesel oil the same. I don't recall specifics, but I plan on switching the Olds to that next time. M -- Mark Mullins USMC (ret.) Tucson, AZ
Re: Zinc levels in oil
Thank you Milton. Those were exactly my thoughts. Wear is wear, that was why I questioned them. I was not happy with the answer, so I am going to switch. Marty McLeod
