1. 5W30 Pennzoil Ultra, API SM synthetic = 115,612 psi
I have not been able to find this oil with the latest API SN certification. The bottle says, “No leading synthetic oil provides better wear protection”. For once, a product’s hype turns out to be true. And this oil provides MORE THAN TWICE as much wear protection as the lowest ranked oil on this list.
zinc = 806 ppm
phosphorus = 812 ppm
moly = 66 ppm
calcium = 3,011 ppm
TBN = 10.3

2. 5W30 Oil Extreme, API SM conventional = 110,286 psi
The Company claims this oil contains their proprietary formula of calcium petroleum sulfontate EP (Extreme Pressure) technology that is NOT found in any other motor oil. They also claim that it will provide 5 to 7 more HP, 7 to 10% better fuel mileage, cut engine wear in half, and will extend drain intervals two or three times safely. This oil is endorsed and promoted by Tech Author David Vizard. And he was so impressed by this oil’s performance that he also became a share holder in the Company. The “Dynamic Wear Testing Under Load” performed here, supports their claim regarding wear protection. This product’s hype about that, turns out to be true.
zinc = 765 ppm
phosphorus = 624 ppm
moly = 52 ppm
calcium = 7,652 ppm
TBN = 23.2

3. 10W30 Lucas Racing Only synthetic = 106,505 psi
zinc = 2642 ppm
phosphorus = 3489 ppm
moly = 1764 ppm
calcium = 2,929 ppm

calcium = 2,664 ppm
TBN = 7.4

10. 5W30 Pennzoil, API SN conventional, yellow bottle, with Oil Extreme concentrate added in = 100,252 psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of only 76,989 psi, and is ranked 53rd. But, with the concentrate added, its wear protection capability “WENT UP A WHOPPING 30.2%”. This is the first additive I’ve ever tested that actually worked as advertised.
zinc = 970 ppm
phosphorus = 749 ppm, this value is 91 ppm lower than the basic oil because the concentrate has less phosphorus in it, which dilutes the overall ppm count of the mixture.
