Looks to me like in at least last couple yrs oil manufactures have stepped up came out with a lot more oils to choose from with the ZDDP needed. Around a yr or two ago on this forum i heard some reasons for going to a roller was the fear oil would become a problem to get. I know i brought up the fact that there are millions of classic cars all over the world with flat tappit cams that no roller cams are going to made for them. The oil manufactures would keep making oils for them.

Here is a better article relating to ZDDP and detergents

That's what the list is for - there are plenty of oils...not "boutique", "speciality" or "not intended for this purpose but it's really good" oils but major brand names - that meet the needs of flat-tappet cam engines.

I update the post as information becomes available, making the best decisions I can on what to include.

The offer remains open for you or anyone else to post a reasonable, rational response supporting CJ-4 oils which I agreed to link into the sticky unmodified.

Personal attacks and conspiracy theories don't exactly meet the test of "reasonable and rational"

But that's exactly what you are putting over on others.

well some people are not rich and a $1 can make or break the weekly budget.
Whats going to happen is a vehicle is going to get 1 oil change thru the coarse of its life and that it, especially if you know your going to sell it in 5 years or so.

There was a fair comment that oil analysis was referenced in the post although results have been inconsistent based on sampling technique, lab used, etc. While I still believe this analysis is a good general guide, I have removed those links and suggest that anyone that's interested do a search on the forum, BITOG and elsewhere for those results. The only verification accepted is manufacturer-provided information or data sheets listing > 1,000 ppm ZDDP.

Based on this, I've removed Red Line oils as they make no claims and publish (that I can find) no data. Using their application finder for a '69 SBC Corvette returned no results. I have an email in to them as well as a few other manufacturers that now claim to have flat-tappet oils. If anyone has Red Line specific information, please post or PM.

Finally, diesel oils remain off the list. It's a heated topic to be sure, but it seems to me to be a risk that's not required given the relatively low cost differential and ready availability of oils in the sticky specifically designed for our cars and this application. 'nuff said.

Mobile makes a deisel oil thats not CJ-4 or SM/SN. along with three others that are CJ-4, a synthetic, a blend. then delvac 1300 that has been changed to CJ-4

Your just kidding right?

Billla, Rislone makes a product called Oil supplement with ZDDP additive, the data sheet on their web site states that is will raise standard SM oil to a ZDDP level of Zn 1700 to 1800ppm and Phos 1500 to 1600. http://www.barsproducts.com/tech/4401_tech.pdf

I've used it with Rotella CJ-4 for breaking in my motor and now am using it with standard SM rated oil. So far so good, thats easy for me to say because I only have 1500.00 dollars invested in my build. If I had 10 thousand I might try something else. Great info on this thread thanks for taking the time to maintain it.......Tim

billla

Thanks, Tim. I've chosen not to list additives, other than break-in additives, as virtually every oil manufacturer recommended strongly against them with concerns about unexpected impact from mixing additives. I'd also say those levels are too high for a street engine and could lead to combustion chamber deposits and other side effects.

Thanks Billla,

last time i started replying to this my building started to shake wildly.... so hopefully that wont happen again.....thks for posting this, it is good info, no reason to include Diesel oils unless you have diesel engine....any benefit they had has been replaced with better oils. Compcams says minimum zinc level is 1000.

Hope everything is OK after the earthquake!

Thanks for posting that link! Quite a wall of text at CompCams, but the key quote is below which reinforces the 1,000 ppm ZDDP I've been recommending from my research. I would push back on their characterization of specialized "race/off-road" oils, as there are many oils with > 1,000 ppm ZDDP that are mainstream brand names - not special, not race and not off-road.

In terms of oil selection, we recommend a high “ZDDP”, Zinc Dialkyl Dithiosphosphate, content oil for the break-in procedure and regular operation. There are several companies that are now offering specialized “race/off-road” oils, high in anti-friction and anti-wear content, to combat this specific problem. These oils carry the SL rating and contain up to 1000 ppm of Zinc/Phosphorous (the Zinc content in today’s “off-the-shelf” oils have been reduced upwards of 20% since 2001 and approximately 35% since 1997).

the scary part of the earthquake is that our buildings are not built to Ca stds....so whats common place with buildings shaking on the west coast has different significance to us.
