Message	at Zspeed about getting them. I do prefer filtration. As for oil weights, I'm following BITOG University recommendations for oil pressures and such. At 3K RPM's, my oil pressure is right at 60 psi. The oil I'm using is a pure synthetic Group IV base stock that my father gets from his company that makes industrial drilling rig oils. I get it by the 5 gallon pale for next to nothing and actually have 5W-40 for this summer and one of the engineers formulated a 20W-50 racing oil for his drag boat that had in excess of 2000ppm of ZDDP. I would be curious as to exactly why Greg recommends the 20W-50 RP since that's actually pretty thick oil at start up. I know he's mentioned the ZDDP levels which may be a lot of it, but I don't want to speak for him. FWIW 0W-40 Mobil 1 Euro is the GTR approved oil. 1996 TT #61 of 300
