OIL - ALL THE DATA

I just re-remembered this exists, and is constantly updated here:

It includes independent lab tests for all varieties of motor oil that this guy has paid for over the years.

- Wear test, at multiple temperatures

- Effects of aftermarket additives

- Oil thermal breakdown tests

Everything you need to make sure you have the right oil, and understand what it is doing.

Skip past the first couple pages of bragging, and down to the gold. Sample of 50 as a teaser, hundreds after the link. The whole page is gold.

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.
