Good stuff
I just switched at 8200K. Quite pricy unless you get a discount somehow. I paid 4.77Q with a discount. Some swear by it and Hotrod Mag(I think?) on SpeedVison TV dyno'd after Royal purpling all fluids including the tranny and they indicated a small HP gain. Is it worth it? If you can pay the same for RP as any other full syn than I say go for it!
