Royal Purple Synthetic
#11
+1 Mobil one. I know a guy who does circle track on weekends and that's all he'll use. Says it's better than Royal Purple and that royal purple just does the best marketing and uses high prices to make us think we're getting the best. Haha I mean it's not bad stuff, just not as good as Mobil 1.

I've used Redline and RP and never had complaints about either. A friend of mine uses RP exclusively in his fleet (800hp Supra, modded 3rd gen RX7 and modded 300ZXTT, and his Evo 8) as well, with no bad results or press ever. Never saw them get any bad press at all.

Yeah i bought 4 quarts of the regular RP today. We'll see how everything goes. Not going to go with XPS until i get some money into the engine... Are there any local parts stores that carry the special socket to take off the drain/fill plug for the tranny?
