Yeah, I don't like their search function either. BTW, have you read some of the UOA's for PP? Sorry that's not about RP but I am surprised how good most uoa's have been coming back. Definately good oil for the money.

 

From what I've been able to see, it is a great product/value.

 

I have seen enough raw dyno charts to understand how they could be used in a "less than completely honest" manner. We had engine dynos in engineering school. Charts must be corrected to standard conditions, temperature, humidity and barometric pressure, (density altitude) to be of any value.

If they dyno tested 2 oils right after each other, that should normally mean that the environmental conditions are the same (not that someone couldn't cheat on them, however) and the 2 likely factors could be the oil temperature and weight. If someone wants one oil, i.e. a 10w30 come out ahead, just test it against a 20w50. Or one oil is tested cold while the other is tested warm.
