redex diesel ''does it work''

[balmer]

Heard alot mixed reports about the redex, some people say does more harm than good others say it gr8...


It any good4 cleaning her out????
injectors etc

[passat 130 tdi]

i have used redex but not in my passat so cant comment about negative effects - im currently using forte treatment at the moment as its meant to be really good when used in a double dose to aid cleaning your vane ring :D

Not sure exactly how it aids cleaning of your ring.. (oh er.) but lowers emmissions enough to get most cars through the MOT test.
Works best if added directly to fuel filter.

[PassSPORT]

I have only used it about twice in my current 02 PD car, haven't really noticed any difference, but the car is running well.
I used to use it on a 1999 TDi Passat i had a few years ago.
The car had got really smoky under acceleration.
But after a treatment of redex it totally cleared it, so I am convinced by it's effectiveness to that extent.

My best recommendation for these TDi cars, is a good hard Italian tuneup every so often, keeps em nicely cleared out. :D

[Shaka1976]

I've been using it for years both the petrol and diesel versions. On almost every diesel I've used it on the improved fuel economy has paid for the redex after just the first fill up.

[balmer]

thanks for the replies! :o



Heard alot good reports about that forte inject cleaner..... :confused:

[dieseljames]

I always thought Millers Diesel Sport was the additive of choice - has this been surpassed by Forte/Redex now?

[cazyp]

thanks for the replies! :o

I've always used forte on my taxis - gets the emmisions down on the 406's and TDis for the MOT a treat.

[passat 130 tdi]

Millers is a mix of cleaner and cetane booster the forte is aimed purely at cleaning the whole fuel system and also post combustion elements are also cleaned supposedly ? I will be back to using millers as soon as I run off this forte as it cant be mixed millers does make the car run alot better when used regular its like using vmax but at a fraction of the cost

[GRAHAM.C]

I use Millers also,have found it great stuff.I had a problem with sticking turbo vanes which was putting my car into limp mode.I gave it a double dose of Millers and in no time my problem was cured.I use it on a regular basis now every time that I refill as directed and the motor runs a treat.

TBH Forte done the same for me in that cold snowy weather when I couldn't be bothered to take the turbo off for a clean lol.

[balmer]

how does fuel additives clean a turbo?

[cazyp]

Beats me - the makers claim that it also cleans parts of the exhaust system inc' turbo. And all I can say is it always seems to work - in Passat taxis and 406's that get a lot of stop start slow city driving without a chance of an Italian tune up very often. Seems to free up those coked up vanes. I use a full bottle to £20 of vmax.

[balmer]

Prob the waste gate veins the turbo... :confused:



Seen that wynns ''gold'' treatment halfords £15, guna give that a blast!!! :biglaugh:

[Clinterous]

I've tried Forte, Millers and Redex. The results are inconclusive:

Forte - car seemed to run smoother, but not a very noticeable difference.

Millers - didn't notice any difference whatsoever.

Redex - Car ran smoother and felt like it was a bit more responsive.

If you do alot of motorway driving, then would suggest not to bother as the heat build of long runs helps clean it up. However if you do alot of short journeys, with little motorway exposure, then there is a higher likelihood of sooting the engine up with parc.

I used to do about 30,000 miles per year, and that's when I tried the fuel treatments and hence probably didn't notice much difference. I only do about 15 - 20,000 miles per year now and the other half uses the car more often for trips down to the local shops. So, once a week, the car gets a screamer from me just to clear it out.

My view is; save the cash unless the car does feel particularly rougher than normal.

[passat 130 tdi]

Only millers ups the cetane rating the others just clean when I use millers the car is alot quieter on start up and the extra 4 points make it alot more responsive just as vmax would

[macquatic]

an Italian tune up
LOL Love that expression!
Being a miserable Scot, that's all my 130 gets.

[RBF]

Also, the Millers works out very cheap in the long run.

On ebay you can buy a bottle for about £10-12 and that do 10 tanks worth of fuel, so it costs you only a quid or so per tank.

:approve:

[balmer]

Im just wondering does the price reflect the quality of the product...




Redex £6
Wynns gold treatment £15

Audi A4's cost more that the Passat so probably not :D
What are you using it 'for?'

[balmer]

Sure there both the same company, near certain its the basic vw engine in audi's apart from the RS4,RS6 etc



Im wanting clean mine out!



Seems B sticking/hesitating just b4 2,000revs only when u floor it in 1st and 2nd?????? :confused:

[Mike McKinstry]

Clinterous-obviously you have been successful in keeping VNT free up to 232K-any other tips on your weekly thrash you can share-3rd gear to redline?

Regards,
Mike

[cazyp]

Mine (taxi) is now coming up to 200'000 and never had a turbo off/clean yet. I just Forte' it twice a year and blast it - 3.5 to 4000RPM - down a motorway for a good 10 min's constant to let that hot air flow.

Some of the other drivers TDi's have 'cleaned' their sticky vanes (all other poss' of the fault code tested first) with £20 of v-max + 1 bottle of forte and good old thrash as above.

Just as a side note one driver always uses v-max, drives his car with a very heavy right foot, has done over 250'000 and has never had 'limp home' boost cut. Hes has had 2 clutches/DMF's in that mileage though..

[balmer]

Keep her lit!!!! :biglaugh:

To be honest, nothing else specific. Up until May 2009 I used to do circa 30,000 miles a year, mainly motorway speed 70-90. So perhpas that has helped. My circumstances have now changed, doing less mileage and the car is used for alot of shorter around town trips. Perhaps it might catch up with me soon and I've been lucky up until now.

The car is still on original clutch and flywheel I believe.

Some days it does get driven hard, but rarely gets red lined as I find the most efficient torque driving range is between 1600-3000 rpm. Some days it gets pampered and driven gently.

I purchased the car from when it had 157,000 miles, so whether it had its fair share of issues before I'm not sure. According to the Audi service database, apparently not.

never for me, unleaded now at 120/litre think of your mpg compared to TDI

[balmer]

I dont know why ppl use that millers!


I put my 1st 50ml in2 motor yesterday and its startn fart at 60mph lyks theres fueling blockage sumwhere! :zx11:



Redex is defo far better!

funny you should say this ,cos mine's been doing this for some time now , usually around 1800 -1900 rpm in any gear , only way around it is to put my foot down a bit more.

[balmer]

Haha! Yes m8!



Mine doing then exact same thing, in 1st and 2nd gear ONLY when u put the boot down!!!!

W T F??? :confused:


Tryd redex helpd lli,but not crued it.
gave millers ago and 1st time on motorway 60mph kept farting? :zx11:

[cazyp]

Have you changed your fuel filter recently?
Are you sure it's not the injector loom causing a misfire?

[balmer]

no hasnt been changed recently...


Could b injectors,as strange tappet noise dont know if its inject OR camshaft :confused:

[cazyp]

First thing to do would stop wasting money on additives and change the oil and all filters. Then take it from there. IMHO Forte is the only additive worth buying - and then only as a possible fix for sticky turbo vanes.

[boidy]

try slick 50 fuel additive for petrol & diesel, it works a treat

[passat 130 tdi]

changed my air and fuel filter tonight £12.91 from europarts - both were alarmingly dirty , so hopefully my stutter might go away now ????

[balmer]

Did fuel filter help?

[passat 130 tdi]

Given that I changed the air and fuel filters YES its made a huge difference

:beerchug:
Now get the oil changed (10 min job) and you'll really notice how quiet it becomes!

Getting sticky vains in my 130tdi bora. Millers would help that???

how do you they are sticking ? and its not something else ?

using millers or forte is going to do some good as it removes carbon apparently . you need to do few hundred miles with it in the tank before it will really start to attack any carbon deposits in a way that will clean the turbo vanes though and the car is meant to be driven like you stolen it.

Its going in2 ''limp mode.'' Always seems 2go in2 it at motorway speed in 6th gear for some reason.

Turbo just switches of completely no boost! :mad:



So give her gd thrashing and shud help sticky vains??
Cost few quid 2get it off and clean!!!!

you have probably got over boost , it will only ever go limp at around 60 - 70 mph , this is when it always seems to happen.

must be at that speed/rev range the system is fully loaded with boost pressures.

take the map sensor out and clean it with industrial alcohol . IPA . or Carb Cleaner.

[balmer]

Tho, had it scanned other day and no faults...

[genix]

Just saw Redex Fuel System Cleaner in Tesco for £1.85 (250 ml = 2 treatments), sounds like a good deal - I guess I am going to give it a try... ;-)

[gewiss1234]

It was a fantastic upper cylinder lubricant in the early days. Modern engines have higher tollerences to run on unleaded (less lubricant.Pinking)
So it may do more harm than good to injection systems, diesels are stronger anyway so I guess the juries out..?

[Eshrules]

millers fuel additive is all you'll ever need.

I used it religiously in the golf and the A4, Redex inspires fear within me.

[genix]

.... Redex inspires fear within me.


What makes you saying that? :nervous:

[Eshrules]

the fact it's cheap for a kick off - if I'm running (what was, new) a £15>20k car, the last thing i want to do is put in poundshop special injector 'cleaner'

second point being, injectors work or they don't, there's no such thing IMHO as a dirty injector.

You're much better off treating the fuel properly, with Millers, to provide a cleaner burn.

A good friend of mine constantly reminds me - buy cheap, buy twice.

[genix]

fair points, though I wouldn't necessarily agree that expensive automatically means better...

[gewiss1234]

Eshrules....... SPOT ON good in its day but things have moved on!

[Clinterous]

Until scientific evidence arrives, we will never know which of these additives is best and whether they do good or long term damage.

you'll be waiting a long time :p nobody will ever want to make the claim that their additives are scientifically proven to be beneficial to an engine.

I can speak from experience though and I noticed a significant improvement in general burn and a slight increase of MPG when using millers. More specifically following the remap than beforehand.

In my opinion and based on personal experience, I wouldn't be putting Redex in any engine.

[genix]

... nobody will ever want to make the claim that their additives are scientifically proven to be beneficial to an engine.

I thought there are already plenty of claims like that (BP and Shell just two of the most common examples) ... :confused:


More specifically following the remap than beforehand. could that explain the noticed improvements, maybe?....

[passat 130 tdi]

i use miller 4 sport - the rise in cetane is felt after it gets into the system ,makes for better cold starts and definetly runs better from cold and alot quieter also. NAILED ON !!!! :D

apologies - for the pedants amongst us, I was referring to the additive suppliers, as opposed to the fuel suppliers themselves.

I noticed a cleaner burn generally, both before and after the remap.

If you want to try redex, go for it - I'm certainly not qualified to advise you against it, merely offering my opinion.

Should you use it and come across any issues though, I'd like to hear of them.

Again, the engine you're intending to put this stuff into isn't a cheap engine.

[Allko]

I travel to Slovakia twice a year and always use redex advanced on one journey.It improves my economy from 46mpg to 50mpg. The engine did run smoother when I used it in my citroen berlingo 1.9d. But on audi 1.9tdi it is no difference. On the other side berlingo made no difference when I used shell v power.On audi it does huge difference. quieter, smoother and better mileage. So I sometimes use the advanced just to get better mileage and always shell v power.
