Anyone used it?
redex isn't designed to increase power.
it a cleaning agent
i use it, and don't have any problems with it. or try millers fuel cleaner
I was just walking round halfords looking for something to buy, not really interested in the power increase more the clense. Everyone loves a good clear out.
I used one of those octane boosters once in my old A4. Didn't feel any difference, and when I did my service about a week later, the spark plugs were completely red stained!
Cheers, might look in to th Millers.
