| Customer Reviews: Average Rating:  Rating : - Noticeable difference in torque in my '02 Mini Cooper S with John Cooper Works. I just started using Royal Purple in my Mini Cooper S with John Cooper Works (basically, the supercharged, supercharged Mini). I actually noticed a difference in torque off the line and squeeled the tires HARD in 2nd gear. Although I don't have all the equipment to register the difference in fuel conservation, the guages inside my Mini started registering higher, expected mileage ranges. I previously would see that mileage range at about 480 miles on a full tank of gas (Hwy), but after Royal Purple, I saw the range jump up to 505 at one time.
Like I said, I'm not an automotive expert, but from what it seems to me, the Royal Purple has made a difference. + See Full Customer Review |  |
