Re: Flat Tappet Cam Users,a New Oil With 1,800ppm Zddp
Corey,Dec 2006 info is NG,there were new Gov/EPA regs introduced on 1/2007 for even further reduced ZDDP lvl's on all oils including the modil delvac .
So what the zddp lvl was on the older gen CJ rated Delvac in 2006 could and likely is less then the newer CI rated delvac 15w-40.
But i tested the newer CJ rated delso and its aprox 1300-1350ppm,the older gen delvac was 1500ppm zddp.
I have had the delo tested mult times and was never as low as the 1199 you have listed,1250-1300ppm was the lowest i had ever seen the delo in all the oil testing had done & that's including the newer reduced zddp post 1/2007 CJ version ,again the Delo site claims at least 1300ppm ZDDP for the newer CJ version which isnt bad.
This may help
The current zddp oil additives on the market are as follows:
ZDDPLUS (TESTED/APPROX 2K Zn & 1,600 P W-6 QTS OIL)
CAMSHIELD (TESTED/APPROX 88KPPM Zn & 75KPPM P PRIOR TO MIX WITH OIL)
MOTORHEADS HI "Z" (BOOSTS ZDDP APPROX 50% OR BY 500-600PPM PER MFG)
LUCAS TB ZINC PLUS (5KPPM ZINC W-4.5 QTS OIL PER LUCAS/MFG)
GM EOS & CRANES SUPERLUBE ENGING BREAKIN CONCENTRATE ARE GREAT FOR FLAT TAPPET CAM/LIFTER BREAKIN & ALSO SHOWED GOOD/HIGH ZDDP LVLS. (BOTH SHOWED APPROX 5,500-6,000PPM ZDDP WHEN TESTED) I USE CHEVRON'S DELO 15W-40 WITH GM EOS FOR THE CRANE LUBE FOR ALL MY FLAT TAPPET CAM BREAKINS. WORKS GREAT AMD MUCH CHEAPER THEN JOE GIBS OR BRAD BENN BREAKIN OILS.
HERE ARE OILS(SOME NEW ON MARKET) WITH GOOD ZDDP LVLS FOR FLAT TAPPET CAM PROTECTION.
1200-1400PPM ZDDP IS THE REC MINIMUM REQUIRED FOR PERFORMANCE FLAT TAPPET CAM PROTECTION AND CLOSER TO 1400PPM AND EVEN LITTLE MORE IS BEST FOR REAL HOT FLAT TAPPET CAMS RUNNING HI SPRING RATES:
CHEVRON'S DELO 15W-40 (NEW CJ VERSION1300PPM/OLD CI -1500PPM AS TESTED AND AS PER MFG TOO)
SHELLS' ROTELLA ST 30WT (APPROX 1250-1300PPM)
NOTE-SHELLS NEWER CJ 15W-40 OIL ONLY HAD APPROX 1050-1100PPM ZDDP WHEN TESTED SO ITS NG IMHP FOR PROTECTING A PERF FLAT TAPPET CAM)
MOTORHEAD'S 15W-40 (1400-1500PPM-PER MFG)
CLASSIC CAR OIL'S 15W-40(1400-1500PPM-PER MFG)
