i had my oil change today and i finaly used royal purple and the car "feels" so responsive, like the turbo spins so easy. i only drove it for 8 miles and all in speed limit cause i was next to a cop the whole time, but ill give it a couple of more miles to see if it was just me. MOBIL 1 out ROYAL PURPLE way in!

 

it should... it's thin

 

The turbo isn't the only thing that spins easy with Royal Purple...

i've heard mixed opinions on royal purple....i used to run it on my first wrx, but never noticed a performance diff. Has that ever been verified?

 

i run motul or royal purple i enjoy both never had problem with oil running out like some claim with royal purple.

 

 

Thats funny right thurr.

 

when i had my STi i chose the Motul over the Royal Purple. the Royal Purple did burn away quick so i went back to Motul. as long as your car likes it, its all good

 

this is an entertaining thread, lol

 

I have used amsoil in my car since new in 2006 25K miles ago. It doesn't burn off and I get good gas mileage too. 20 mpg in a stage 2+ SS tuned STI.
