    A good fuel cleaner and proven to work.

    I saw YouTube video reviews of this stuff where customers have before and after using this product showing the carbon buildup removed from the pistons.Theres been nothing but good reviews and it definitely cleans off carbon build up. I’ve used cleaners in the past but not really felt it it worked (e.g Redex, STP etc). But this stuff just after half a tank has made my car feel abit quicker and that it feels it runs better than it did before using it. I’ll will be using this cleaner again.

    Amazing product.

    I'm not normally one for leaving reviews but this redline cleaner deserves one. I bought it as it's the only cleaner that I could find that had a guaranteed high content of Polyetheramine (PEA). As far as I am aware this is the only chemical that is effective in cleaning injectors/fuel system. My car (Honda Civic 1.8) has always been highly maintained and runs great but it always seemed to lack low down torque. I thought I'd give this a go just in case the injectors were dirty. Well, after a tank full with the whole bottle of cleaner it has made a very noticeable difference. It's like I was driving with the hand brake on. It is like night and day and can hardly believe it myself. I thoroughly recommend this cleaner!

    Red Bull for your Car!

    Should be called 'Red Bull for Cars!' It's that good! Best additive I've ever used, and my old, 190,000 miles, car is running like a good un on it! Highly recommend this stuff!

    The ronseal of cleaners does what it says

    Bought for my speed triple and makes a noticeable difference,used about 1/3 rd bottle on full tank and engine deffo smoother and pulls slightly stronger,seems almost turbine smooth when running not that it was rough before but weirdly very smooth.
