I've used it back to back on a dyno. Fresh ENEOS vs fresh Royal Purple. Picked up 7-9 HP throughout the RPM band. While not a substantial number in itself, it's pretty substantial gain over a highly regarded synthetic oil.
I have used this oil in the last year in a way which I would say is "severe duty"
-60 1/4 mile runs
-16 dyno pulls
2400 street miles.
Car is a 1994 Supra Turbo Single. It makes 512RWHP (620+HP at the crank) on pump gas. Car has 122,000 miles on it. I like this oil alot and will continue to run it.

I thought your Supra made 400HP and had a loss of compression in one cylinder? At least that's the info from your AutoRX thread. Curious as to why you'd throw more boost at an engine that has an obvious "bum lung" as per your compression test results.........
My compression results were perfect after Auto-RX. Not sure if the Auto-RX was the cause or if the initial compression test (I didn't do the initial compression test) was done improperly. I didn't add any more boost per se, just a larger turbo...

What I thought was interesting was the offered to sell me the exact oil they use in the F1 car! It was an 0W70, but the cost was out of this world. IIRC it was on the order of $50-$60 per quart!! Makes for expensive oil changes!!
