How much is Mobil 1? I paid $4.74qt for Royal Purple. I can't imagine Mobil 1 being much less. My point is that Royal Purple isn't an arm and a leg more expensive than the best, Royal Purple. Not to mention that I've seen dyno slips that show additional hp and torque gains simple with the addition of Royal Purple, can't say I've ever seen the same from Mobil 1. This is not to say that Mobil 1 isn't a good choice, I'm simply showing that cost alone shouldn't be the deciding factor in not going w/Royal Purple.

 

mobil 1 full synthetic on mine since she was 300 miles old
did it the first weekend of getting her that and a good 10 micron filter for her.


tranny is running the full synthetic also from them . ( i belive LOL need ot do it again soon )

but my whole car has been switched over to teh synthetic and the shift kit was put in it at the same time

 

does mobile 1 add hp?
