A question to the Forum, I topped up my Type s GT 2.2 the other week, a full tank of normal diesel, not BP Ultimate like i normally use. I put 125ml of the redex in the tank as directed on the bottle, [half the bottle]. I drove to Scotland and back, approx 600miles. Ive not used the other half of the bottle yet but my car definitly feels a bit more punchier off the throttle. The question i want to ask you guys and girls is: At £6 a bottle for two full tanks, is using this stuff worth it. I just want your opinions especially if anyone else here has used it. My car has 18000 trouble free miles and from day one ive only used BP Ultimate fuel or V-power if i can get it. Your input and advice would be greatly appreciated.
