    Default Redex - whats your experience?

    Put a dose of this when filling up last week and engines smoother at idle and a bit free-er when putting the foot down.
    Fill up with V-Power which has cleaning agents but even then, this stuff improved things.

    Your experience?

    Yes the same. Saw it used on an older car on Top Gear, that measured hp before and after, added about 20hp I think, so it does work. Tempted to try a Terraclean.

    Your experience?
    I believe this contains Ethanol, isn't this what causes the fuel to burn slightly better because of energy density being less?
    Depends on the age of the car, with some manufacturers it might invalidate the warranty.
    Otherwise it's just Foo for cars.

    Not really, there was a measured increase in horsepower in that segment of TG.

    Mostly I suspect from the Redex cleaning the injectors.

    On an older engine take the sparkplugs out, tip in a teaspoon of Redex, put the plugs back in, leave overnight. When you start the engine it will smoke a lot at first but quickly clear. Makes a big improvement as this frees up gummed piston rings and softens carbon build up. In the fuel it cleans fuel lines and injectors and carburettors, if you still have one lol.

    I've still got one. I took it off one of my modified cars about thirty years ago and it's hung on my garage wall since!

    (it's a Japanese Hitachi made 'flat top' SU HS4 carb from a Datsun 260Z, I had it on a tuned Mini)

    You're obviously old-school Ian. Haven't heard that tip for donkey's years.

    I am mate, I was always getting my hands dirty on the old nuggets I used to own. I had and still have a soft spot for 2 stroke engines, Redex was brilliant for de-coking them. God I miss my old Yam RDs.

    I wouldn't call it foo. It's based on sound science, and it doesn't need a fertile imagination to observe the results.
