Group,
Coming from a rotary world, i can only say that Royal Purple products where the ones to be chosen as far as wear reduction, heating and HP (yes HP) improvments.
I am a true fan of RP with my previous car (Maxda Rx-8). I did about 15 track events over the last 3 years and had different oils analysed. RP was always the winnner...
My Z will be arriving next week and you can be sure that i will switch to RP as soon as i hit the 5-7K mark.
Anyone using RP products in the Z world?
