Here's the ranking list:
For those folks who are interested in this real world test data, below is the “Load Carrying Capacity/Film Strength” ranking list from all the real world motor oil “Wear Testing” I’ve performed so far on new oils, at a representative operational temperature of 230*F. The list includes modern API certified low zinc oils, traditional high zinc High Performance/Racing oils, Diesel oils, low zinc oils with zinc additives added in, and Break-In oils.
Lower ranked oils are not necessarily “bad”, they simply don’t provide as much wear protection capability as higher ranked oils. If you have been running a low ranked oil in your engine without issue, that doesn't mean you have a great oil, it only means that your engine's wear protection needs have not exceeded that oil's capability. And as long as your engine's needs don't exceed that oil's capability, you will never have a problem. But, if unexpected circumstances come up that make your engine's needs exceed that oil's capability, such as an overheating condition, an oiling condition, a loading condition, some parts heading south, or whatever, your engine can end up junk. But, if you'd been using an oil with a much higher capability, it could still provide enough extra protection to save your engine. So, each person has to decide for themselves, which motor oil provides the wear protection capability they are comfortable with, for any given engine build.
All oil bottles involved in the testing were thoroughly shaken before the samples were taken. This ensured that all the additive package components were distributed uniformly throughout all the oil in the bottle, and not settled to the bottom.
Test result differences between oils of less than 10% are not significant, and oils within that range can be considered approximately equivalent.
An oil's "wear protection" capability that was tested here, and an oil's "friction reduction" capability, are two entirely different things. While this test data provides excellent information about an oil's ability to prevent wear, it says nothing about an oil's ability to reduce friction. So, the data here will not provide any information regarding differences in HP potential.
The ppm quantities of zinc, phos, moly and in some cases titanium, shown in the list, are directly from the Lab Reports that came back from the Professional Lab “ALS Tribology” in Sparks, Nevada. Some oils have more zinc than phos, while other oils have more phos than zinc. It just depends on the particular oil’s formulation. Either way, the numbers are correct and are NOT typos.
NOTE: The higher the psi value, the BETTER the wear protection. And this applies to ANY engine, including High Performance flat tappet engines.
That psi value is determined by the testing "load" being applied (which of course, is the EXACT SAME for every oil tested), over the "area" of the wear scar that is created on the test specimen, as the test is being performed. So, the result is "pounds" of force being applied over the wear scar "area", which is in square inches. Or in other words, pounds per square inch, which of course is just shortened to "psi". The better an oil's wear protection capability, the smaller the wear scar will be on the test specimen, and the higher the resulting psi value will be.
Oil categories for gasoline engines:
• Over 90,000 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
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.
