    I’ve never actually used this stuff. Is it worth it? I have a 4.5 year old fiesta tdi and do quite a bit of town driving and have had the dpf light come up before so was thinking maybe use as a preventative measure but I don’t really know if it actually works or is just a con.
    Won't do much for your dpf, needs to get hot to run off debris. You're better off taking out for a longer run around once a week.

    Had an 3.0 Turbe Espace years ago that used to go into limp mode a bottle of this with every tank for a couple of months solved it.

    I am never sure if these are any good - there are so many variants that all claim to clean a different part of the engine - do they offer much more than the detergents in the premium fuels?

    Does this help prevent EGR and/or DPF issues in a diesel engine?
