I just received this sample today of a recently purchased gallon from Walmart.

I was unable to find a sample of this old spec oil online. I was really curious to see how much detergent/dispersant, phosphorus and zinc was in this oil.

Enjoy.
 
Thanks for sharing. Have been curious about this oil as well. Zn and P a little lower than I would have guessed but still plenty.
 
I have been running this oil in my 92 Toyota pickup with the 22RE engine in it for about 19 years and 290,000 or so miles.

Since I moved to NH from SOCAL, I have been using multigrade Rotella T6 5w40 for the six months of winter. I switch back to Rotella 30 for summer months.

I now have 310,000 miles on the original block. Cylinder head has been replaced twice due to head cracking. Buying a new aluminum head casting and using all new valves and springs seems to have fixed it for good. Fingers crossed. Good compression and no make up oil added between 4,000 miles OCI's.
 
Thanks for the VOA. It's rare to see data for a SAE 30 monograde.

Zinc is fine at 938 ppm, Moly is a nice surprise at 93 ppm.
The detergent package (Ca 2022 + Mg 182 = 2204 total) for be ample for 5k to 7k miles.
KV100 = 11.1 cSt

Now compare this to Mag1 SAE30, which is another monograde I recently found with an excellent data sheet. It's a modern API SN oil, so probably Group II to pass the SN deposit tests. This also means good oxidation stability and better cold starting compared to the old style Group I monogrades.

Quote:
SG / Density = 0.877
KV40 = 87.96 cSt
KV100 = 10.94 cSt
VI = 110
Zinc = 850 ppm (0.085 wt%)
SA = 0.92 %
TBN = 7.0 (D2896)
Noack = 6.1 % (D6375)
HTHS = 3.38 cP at 150 C
Boron = 180 ppm
Ca = 1900 ppm (0.19 wt%)
Moly = 40 ppm
FP = 210 C (D92)
PP = -33 C
Sulphur = 0.3 wt%


This shows the advantage of a monograde, you get more HTHS for you given KV100 viscosity - so a stronger oil, and get a lot less Noack volatility - so a cleaner oil. Plus you get a completely shear free oil with no polymer VII to hack up with the engine.

Sure if you live in a cold climate, the monogrades are too difficult, but here I only have two seasons, hot & dry or very hot & wet. I could easily run those SAE 30's year round.

I'm running an A3/B4 multigrade in my car right now, I would have no concerns running those SAE30's instead.
 
I am running 3 qts of Rotella T1 SAE 30 mixed w 4 qts of Mobil 5000 5w20 right now in my Dodge 5.7 Hemi. Using for an Auto RX rinse. No problems. Amsoil 0-20 SS after rinse.
