Changing to penrite now I think, seeing as people are saying its on par with RP. Im using valvoline atm, and feel like im stinging a bit on the car and putting crap oil in.

I had trouble finding this oil test from years ago. It wasn't without controversy though and was published in Street Homodores!

Run Royal purple in my BF Turbo Ute, and will be in my BFII F6 when I service it soon. I work at supercheap and can get it for as much as your Hi-tech Fast flowing Nulon 10w-40 or penrite equivalents, happy to help people out in perth if you come see me or contact me ****not trying to advertise selling anything or whatever, not intentionally trying to do the wrong thing, moderators please let me know if I can't write that and I'll happy delete this comment**** While Nulon and Penrite are both very high quality oils I'd still pick RP anyday. as for castrol edge, I personally don't believe its quite up to standard. Was my personal opinion for sometime, and that became a stronger opinion when castrol edge was apparently the reason for a mate needing a new engine.

has anybody been able to find kinematic viscosity figures for the RP stuff?

Didn't they give you that when you got it tested?

Send some to me and I'll do it for you if you want

Agree, I run Amsoil AMO 10W40 and had a filtergram analysis test and after 10,000 klms it was in very good shape.

Filtergram isnt the best test, only checks for wear debris and carbon basically. Needs 1 drop of oil.

You really need TAN and TBN for engine oils, viscosity index as well.
