Anyone used Redex Diesel in an old engine

[FrankNicklin]

We have a 52 plate 1.9 Ducato based Swift with 45K on the clock. Was thinking of adding Redex on the next fill but concerned if its never been done before and there is a lot of coke/soot could it cause engine issues. Any thoughts please.

2000 plate, 46k miles. Used Millers diesel additive first time last year and it made the old Ford engine noticeably quieter.

highly unlikely it will do any harm , and probably not likely to really do much at all

Must admit I'm not sure. I bought a couple of bottles on a deal then got cold feet actually using it.

I remember using it donkeys years ago and if I remember correctly I did see more smoke than usual until it settled down.

The only additive that I have known to have along term detrimental end was oil stop leak , which would soften the seals and cause them to swell stopping the leak but then would end with a severe failure causing a much worse leak . But it would buy some time .

In the early stages of my V40's egr cooler clogging up, Redex would put the engine light out, but only for a couple of tankfuls then it would reappear. It must have had some effect to manage to knock the light out but it was fighting a losing battle against modern "environmental" add-ons ? Might get you through an MOT though ?

I throw a bottle of Redx into my tank about twice a year, not because there is anything wrong, I just like keeping it that way!

From my Landrovers, an N Reg and the current 55 plate Transit I put fuel system cleaner in a tank full of decent diesel before the MOT to help with the emissions. It dosnt make a noticeable difference to performance but must be cleaner so I wouldn’t bother at any other time.
