At this current time, Amsoil and Redline are the market leaders in oil. At 6k of miles, they show less wear than RP would show or any other oil.
Lab testing is the REAL TRUTH. Unless all you care about is your HP, not how your engine wears and lasts overtime.  |
No you didn't bring a tornado into this.
The top engine builders in the world didn't use a tornado or Amsoil to win the compettition they used RP.

I use RP with good results, increased power, cooler running engine and better gas milage.
Independent tests clearly document the power, protection and performance of Royal Purple® Motor Oil.

Film Strength based on comparison of leading 5W30 vs. Royal Purple® 5W30 Motor Oil in Falex No. 1 "high pressure" test. (Scar widths mm. Leading 5W30 motor oil: 5.9 mm - scored; Royal Purple® 5W30 Motor Oil: 1.4 mm - polished.)
2
Oxidation life based on U.S. Bureau of Standards TFOUT oxidation test (leading synthetic 5W30 oil - 409 minutes; leading 5W30 mineral oil - 246 minutes; Royal Purple® 5W30 - 1300 minutes.)

Terminology:
CO = Carbon Monoxide (a poisonous gas);
HC = Hydrocarbons (unburned fuel - normally occurs when fuel to oxygen mixture is too rich);
NO2 = Nitrous Oxide (cited as a contributor to smog, ozone, acid rain and regional haze and is exacerbated by the elevated combustion temperatures of “lean burn” engines where more oxygen exists than is needed to completely burn the fuel);
HP = Horsepower;
CO and NO2 are typically on polar opposites. When one increases, the other decreases.
