I've used it for the last 5 years or so..
Don't know if it makes any difference as so far I've not had a fuel problem..
Maybe I should shut up i o tempting providence...
Cheers Bob E...
thanks Bob I suppose a got indication of whether it works, apart from the fact you have had no problems, is the conditions of your pre filters when you do your servicing. Did you get to see them?
I've used it for the past few years, with no problems. But like BobE can't tell whether thats due to the additive or not. When I changed the filters this year there was a little bit of muck in them. But no gungy stuff. Don't know if this helps or not.
Cheers
