I used to run Chevron Delo CI, but I agree with Doug's concerns about high detergent levels. I have gone back to passenger car oils (currently just Castrol 10w-30) but with a bottle of ZDDPlus.

I think its risky to assume the zinc levels are REALLY in the oil in question. Formulae change--even when the designation (CI/CJ, SL/SM) may not.
However, Amsoil/Redline/BradPenn/Royal Purple are probably excellent,safe, choices because they cater to our niche market, I just prefer to dump the additive in myself.

BTW, I posted two staveley analysis of Chevron Delo 400 LE 15w-40 (thats the CJ-4 formulation) last summer. The Zn numbers were between 1275 and 1300ppm.




Greg,were those samples new our used oil.I have noticed that our used oil (between 18/20k miles) have a higher zinc content than new.I assume some of that zinc is from engine wear.We run the same oil in 50+ Dt466's and a 8 road tractiors with NP400 Cummins.

These were new samples, pulled directly from our 2000 gallon tank and the dispensing gun (nozzle) in the plant. Not from a crankcase.
I was guessing the levels would be more like 1100ppm (considering it was LE CJ-4) and was surprised at the results.
I still feel more confident adding my own additive though!!

years ago kendall was the hot ticket recomended to me by several racers and such(str8 40 for my application). From what I gather they were bought out and no longer run the formula that everyone was after. I have searched out other alternatives and found BradPenn oil. I think its the good stuff everyone was after. Check out their web site. http://www.bradpennracing.com/




Brad Penn is coming from the old Kerndall refinery in Bradford,PA.And the analysis I had done on Brad Penn Grade 1 20/50 racing oil.Sure beats guessing and heresay,lets see some of the others.





Penn Grade 10W30 in my flat tappet 496 stroker.

There are answers all over the board here. I wish I felt comfortable with a recommendation.

I am using Delo 400 with a bottle of Comp Cam break in lube. Every time I change the oil, I add a bottle of it. I am also running the EDM lifters.
