I guess the story of cleaning carbon deposits are all wrong for the following instructions .What I know is that hit from 30 up to 80 MPH with the engine getting red line and then after hitting 80 MPH, let the car slown down to 20 MPH and then as soon as you get 20 , step on gas pedal till you see 80 on the speedometer .Repeat this 3 times in a month .....
Well, I also think that the very best way is to use a professioal lengine cleaner
