REDEX Diesel Particulate Filter Cleaner on offer. Is it worth it??

My car clearly states -No Additives. Is this an additive though?
 
No, leave well alone in my opinion. Same as these EGR valve sprays, just step away.

Only my honest advice.
 
The one snake oil I have read positive reports about is made by Forte.
Not cheap but apparently that is because it works.
 
Back in the day it was popular to have a shot of Redex for every gallon of petrol put in your tank. It had a good pedigree. Can’t say whether this is any good but if you’re having issues I can’t see how it would hurt.

Back when I was young, thin, hairy and gullible I worked for the Long Life Tyre and Battery Company, and we sold many car products.

We had an amazing display under a clear dome that housed the ‘’Sparkright 2000’ system that boosted your coils power, and the display was impressive, a spark plug with a impotent limp wimpy spark, would turn, at a flick of a switch, into a raging torrent of a spark, something you’d expect Dr Frankenstein to use to bring life to his creation!

SparkRight claimed this device would give you ‘up to’ a 20% fuel saving! I wandered around the shop, and realised that with Platinum tipped spark plugs giving ‘up to’ 10% GTX up to 10% Redex, plus a few more, if all of them worked I’d be using no petrol at all!

I put this theory to my Manager, (I was 17 and the lowest of the low, only useful for lugging batteries round and doing the dirty dangerous jobs) and suggested that he donated all of the said products so I could evaluate my theory.

He thought it was a great idea and favoured I buy them using my 15% staff discount rather that the Company’donated’ them so the evaluation never got done

I could have discovered perpetual motion!
 
I do find it hard to believe much gets through to the dpf after combustion. I know redex was popular in the past but that was said to be a carburettor cleaner and valve stem lubricant before combustion.
 
Redex is an excellent carbon 'solvent'. Left overnight in the cylinder of a hot engine it would remove most of the carbon - mainly of use in the past when engines needed decarbonising.
 
I have to confess to purchasing an additive for each tank filling for the last month.

Both the private garage and the local AA man suggested that it might help with combating the engine warning light that I get regularly when climbing hills.

So I've followed the advice a poured a bottle of the suggested product into the fuel tank before filling up.

I can't claim that it has cured the problem but certainly less red lights and not one occurrence of the more severe event when the engine just 'goes to sleep', still running but at tickler speed, until I choose neutral and rev the engine, when power is instantly restored.

So possibly of use on a 25yo Ducato?

The emissions light comes on every few months on my diesel V40 (already had the egr cooler replaced as a recall) and I find a bottle of the Redex diesel treatment clears it, usually towards the end of the next tank full. I was buying it at Toolstation, but have got it from Aldi and Tesco on offer at £4 a bottle. Last month I filled up with premium diesel to give that a try (so far so good) but Mr Wallet wasn't too happy, worked out a lot dearer than standard diesel even with a bottle of Redex on top ?
I tried Dipetane that I got off the internet, but it wouldn't clear the light, even after 3 consecutive fills.
My old favourite,trusted garage (retired now) recommended the Forté products.
 
At the end of a tank of fuel just before I fill up when the engine is up to temp I drive for around 15min in low gears and with high revs and give the engine and dpf a good blast.. otherwise known as an Italian tuneup, I have been known to put in some miller’s diesel treatment…😎
 
Snake oil is snake oil, but if you want to oil a snake.
Results of using Liqui Moly Diesel purge ( to clean injectors) on my Fabia CAYC engine.
injector variation pre-post-clean.jpg

LHS was pre filing with diesel purge, rhs after running for one week.

VW spec on injector variance is +-1.
Fiat spec on injector variance is +-2 but currently inj1 is about 4 , so there is a litre in the tank ready for 220miles to Pembroke
 
The best "additive " for any engine is knowledge. The type that can be extracted from your Obi wan kanobi (OBD2 port) Is my regen process doing as it should yes/no don't need snake oil why not look for cause (over fueling due to xyz). Regular tests on injector variances do i need to throw in some cleaner regularly or once in a blue moon. Just a home brew version of TPM (total preventative maintenance)

Some time ago the dpf came up fault on the dash and consequently into limp mode we continued our next 50miles although slowly to say the least, I then bought some dpf cleaning additive which lowers the temperature of ignition of the fuel from the1200 degrees needed to ignite and burn off the soot build up in the dpf, I was very sceptical but after being parked over the weekend we set off still with the light on but after 5 miles or so regeneration took place and the engine ran as it should, but I still had a light on so had to replace the dpf pressure differential sensor to put the light out.
 
Part of the problem with my car is the odometer has the option to display "live" mpg. The missus will come in and say "It's showing 67 mpg on the drive back from my sister's, aren't I doing well ?" so I have to go out and flog it within an inch of its life.
Just realised that the light's never been on since she got her knee replaced 5 weeks ago and I've been doing all the driving !
 
Noticed today middle of lidl had a twin pack of redex didn't catch the price though
 
Slight diversion here (sorry), but would fitting a DPF on an otherwise too old van make any difference to getting a crit air cert?
Personally from what I read on the official site, I don't think it does, but others elsewhere say that it does. :?

You have to get it recognised by DVLA etc.... Have heard of others retro fitting this and cats too. Expensive job though.

I don't think that would affect the French regulations? (Crit air is French and seems to be solely based on age and type of vehicle.) I have no idea of the regulations for the clean air zones in the UK, as there is zero chance of my taking any vehicle into any large city centre.

You probably know better than me then. I was (probably wrongly) assuming they looked at the vehicle details as recorded by DVLA?

Being on offer isn't a reason to buy. If it's any good it's worth full price. If it's snake oil it's snake oil.
 
There two types of "DPF" cleaner, one does not clean the DPF at all, what it does is effectivly reduce the temperature of regeneration and help do what the manufacture expected , regeneration is intended to complete combustion of all products in the dpf and slowly clog it all up with non combustables.
A Process that actually cleans out the clogged stuff is typicaly done to a removed DPF in a machine.
there are also some chemical cocktails designed to do the job without affecting the glamorous materials in the cat and dpf.
if your engine is running ok and under control shouldn't require the former.

We thought that putting red ex into your cylinders through the spark plug hole would do a cheap de coke. All it did was fill the street up with smoke.

I think they did recommend it to be used like that I had a friend that did it with a Citroen Dyane clouds of smoke everywhere as you say
