Wear protection reference categories are:
• Over 105,000 psi = INCREDIBLE wear protection
• 90,000 to 105,000 psi = OUTSTANDING wear protection
• 75,000 to 90,000 psi = GOOD wear protection
• 60,000 to 75,000 psi = MODEST wear protection
• Below 60,000 psi = UNDESIRABLE wear protection
All the oils were tested at a representative operational temperature of 230*F.
The HIGHER the psi value, the BETTER the Wear Protection.
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. “Oil Extreme concentrate” added to 5W30 Pennzoil Ultra, API SM synthetic = 111,570 psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of 115,612 psi, and is ranked 1st. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT DOWN 3.5%”.
zinc = TBD
phosphorus = TBD.
moly = TBD
calcium = TBD
TBN = TBD
3. “Oil Extreme concentrate” added to 10W30 Brad Penn, Penn Grade 1 semi-synthetic = 111,061psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of only 71,206 psi, and is ranked 92nd. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT UP A BREATH TAKING 56%”.
zinc = TBD
phosphorus = TBD.
moly = TBD
calcium = TBD
TBN = TBD
4. 5W30 Oil Extreme, API SM synthetic (per the Oil Company, even though synthetic wording is not shown on the label) = 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 results from the “Dynamic Wear Testing Under Load” performed here, fully supports their claim regarding wear protection. So, their hype about that, turned out to be absolutely true. And since this oil beat every high zinc oil I’ve ever tested, it also proved another one of their claims, that using zinc as the primary anti-wear component, is outdated technology.
zinc = 765 ppm
phosphorus = 624 ppm
moly = 52 ppm
calcium = 7,652 ppm
TBN = 23.2
5. 10W30 Lucas Racing Only synthetic = 106,505 psi
zinc = 2642 ppm
phosphorus = 3489 ppm
moly = 1764 ppm
calcium = 2,929 ppm
TBN = 9.0
NOTE: This oil is suitable for short term racing use only, and is not suitable for street use.
6. 5W30 Mobil 1, API SN synthetic = 105,875 psi
zinc = 801 ppm
phosphorus = 842 ppm
moly = 112 ppm
calcium = 799 ppm
TBN = 7.5
7. “Oil Extreme concentrate” added to 10W30 Lucas Hot Rod & Classic Hi-Performance Oil conventional = 105,758 psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of only 62,538 psi, and is ranked 110th. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT UP A MIND BLOWING 69%”.
zinc = TBD
phosphorus = TBD.
moly = TBD
calcium = TBD
TBN = TBD
8. 0W30 Amsoil Signature Series 25,000 miles, API SN synthetic = 105,008 psi
zinc = 824 ppm
phosphorus = 960 ppm
moly = 161 ppm
calcium = 3,354 ppm
TBN = 11.4
9. 10W30 Valvoline NSL (Not Street Legal) Conventional Racing Oil = 103,846 psi
zinc = 1669 ppm
phosphorus = 1518 ppm
moly = 784 ppm
calcium = 1,607 ppm
TBN = 4.4
NOTE: This oil is suitable for short term racing use only, and is not suitable for street use.
10. 5W50 Motorcraft, API SN synthetic = 103,517 psi
zinc = 606 ppm

moly = 3 ppm
calcium = 2,707 ppm
TBN = 7.6
12. 5W30 Amsoil Series 3000 Heavy Duty Diesel Oil synthetic, API CI-4 PLUS, CF, SL, ACEA A3/B3, E2, E3, E5, E7 = 102,642 psi
This is BY FAR, the highest ranked Diesel oil I have ever tested. This oil is Engineered for Diesel engines not equipped with Diesel particulate filters (DPF). Amsoil says this oil delivers better wear protection than other popular Diesel oils. And in this case, their hype is absolutely true. They also say it effectively reduces fuel consumption, with its advanced fuel efficient formula. This oil costs $11.15 per quart in the 2013 Amsoil Factory Direct Retail Catalog, which is 10% more than Amsoil’s 5W40 Premium Synthetic Diesel Oil. So, in this case, you pay only 10% more for the Amsoil Series 3000 Heavy Duty Diesel Oil, but you get a whopping 33% more wear protection than you get with the Amsoil’s 5W40 Premium Synthetic Diesel Oil. Money very well spent, if you run a Diesel oil intended for engines not equipped with Diesel particulate filters. The next highest ranked Diesel oil only ranks a very unimpressive 54th out of the 124 oils I’ve tested so far. So, this 5W30 Amsoil Series 3000 Heavy Duty Diesel Oil is in a class of its own, among all the Diesel oils I have tested.

13. “Oil Extreme concentrate” added to 5W30 Mobil 1, API SN synthetic = 102,059 psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of 105,875 psi, and is ranked 6th. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT DOWN 3.6%”.

calcium = 2,664 ppm
TBN = 7.4
15. “Oil Extreme concentrate” added to 5W30 Pennzoil, API SN conventional, yellow bottle = 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 73rd. But, with 1.5 OZ of concentrate added per qt, which is the bottle’s instruction for street driven vehicles, its wear protection capability “WENT UP A WHOPPING 30%”.
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 diluted the overall ppm count of the mixture.
moly = 285 ppm
calcium = 4,443 ppm
TBN = 18.8
16. 5W30 Chevron Supreme, API SN conventional = 100,011 psi

This oil costs $11.15 per quart in the 2013 Amsoil Factory Direct Retail Catalog, which is 10% more than Amsoil’s 5W40 Premium Synthetic Diesel Oil. So, in this case, you pay only 10% more for the Amsoil Series 3000 Heavy Duty Diesel Oil, but you get a whopping 33% more wear protection than you get with the Amsoil’s 5W40 Premium Synthetic Diesel Oil. Money very well spent, if you run a Diesel oil intended for engines not equipped with Diesel particulate filters. The next highest ranked Diesel oil only ranks a very unimpressive 54th out of the 124 oils I’ve tested so far. So, this 5W30 Amsoil Series 3000 Heavy Duty Diesel Oil is in a class of its own, among all the Diesel oils I have tested.
