Can anyone suggest a good diesel additive/cleaner? I have not used one in a while and I used to use redex but there must be something out there that is better now?

Millers diesel sport 4 everytime

Technically your not supposed to add anything as it may invalidate your warranty. Millers is just a cetane booster not a cleaner and Redex (Even the new ones) is just overpriced gunk. The best system cleaner you can buy is Forte. You can add it to the tank or run it neat through the fuel filter. It's about the best you will get short of a pressurised purging system.

Forte

I have my last bottle of millers in my boot

I must remember to use it up

I havent seen any gains what so ever using it over months

So much

I have a bottle rolling around in the boot

Millers is just a cetane booster not a cleaner

But i remember before they sold something called "Millers Diesel clean" but must also agree that Forte is damn good stuff

Millers is an injector cleaner and lubricator as well as a cetane booster.

The following comes from the millers site here (my bold added):

Try with Liqui Moly

Products - Super Diesel Additiv

I using this additive every 3-4k km, and my 2,0 TDI (with steinbauer p-box) running very smooth.

I really wouldn't try that liquid moly. I don't know what is in it, but it looks like it could be the old moly based compound. If it is, that makes enough of a mess of the old ford endura engines that I wouldn't like to see it's effects on the PD injectors.

Enough people on here have used the millers to suggest that it probably won't cause damage and forte is used by a fair few garages.

All LM products are TUV certified. On LM site you have all security and technical data sheet's (and you can compare ingredients with other additive).

That additive are fully compatibile with all modern diesel engines, and isn't moly based, because, it's impossibile to add any type of moly (MoS2) in fuel.

Why not use V-power diesel?

Cleaner than normal diesel, higher cetane rating, more power & better fuel economy and it cleans the engine (as does shells diesel extra)

Won't void your warranty.

No messing around with additives.

Perhaps not freely available in Barnsley; good suggestion mind you but why not go one better ....

...... use V-Power Diesel and Millers Diesel Sport 4 - I do!

Because it costs a fortune (about 6p/L more) and gives reduced fuel economy over shell derv, derv extra or the supermarket fuels.

The millers costs about £10 for 500L eg £1 per 50L tank, so 2p/L and from what people on here say seems to have positive effects.

I certainly used to run millers in older dervs, esp pre MOT and you could easily tell when it wasn't in the tank. It was great at a pre MOT smoke reduction too.

Because it costs a fortune (about 6p/L more) and gives reduced fuel economy over shell derv, derv extra or the supermarket fuels.

The whole point of v-power diesel is that it gives you more miles per tank than ordinary diesel and also more power. Yes it does cost more.

Hi, I have been using Millers on and off for the last 60,000kms and you can definitely notice when it is not in the tank !! The most noticable gain is trottle response in the lower rev range, very noticable!

Best additive is taking it for a drive and keeping it in the high rpms once the engine is warmed up properly. The increased volume/pressure of the gases flowing through the engine will clean everything properly. Does wonders for the ole' DPF too.

Some smoke is bound to come out in the beginning but it will feel a lot better once you're done. Let the engine idle for 2-3 mins when you're back to protect the turbo too.

in other words; take it for a 'Brisk' drive.

Maybe somebody should tell the 5 diesels of varying brands including VAG I have use of this, because I can assure you it doesn't give any more range and in all of our cars gives less.

I'm not the only person on here to say that V-Power gives less MPG and I for one did that over a few tanks brim to brim.

As for more power... if you say so, but I'd suggest that RR figures dont agree.

Still if you're happy to believe it and want to keep paying more for your derv, then feel free as I'm more than happy for you to subsidise the standard fuels.

Mine never spends enough time in the tank to age:thumbup:

Yeah I must admit I was somewhat amused by that point too

So what is the point of v-power then? sensible answers please!

I rarely use it, but it seems to me to be more responsive and give me more miles per gallon when I do.

Perhaps strangely, I've noticed no positive effect from Millers since the hybrid went in (same economy and smoke). Perhaps because I had a stretch of not using it (due to running out and not replenishing). But maybe more importantly, I've not used my usual Shell since starting on it again, three tankfuls ago. This has been due to never being in the right place at the right time

So maybe there's also a link between which fuel brand you're using Millers with? :rubchin:

Just a thought....

For what it is worth, here is the text of a post I did in this thread;- http://briskoda.net/fabia-i/millers-diesel-power-sport-4-a/71245/

just about a year ago;-

"I tried some Millers 4 with V-power in my Octy vRS when it was young and it didn't seem to make any particular difference. I have since done a comparative test of two tankfuls (50 Litres/450 miles) each of V-Power, BP Ultimate, Shell regular and back to V-Power, all without Millers, to work out which fuel I preferred.

The BP Ultimate and Shell V-Power seemed more responsive and quieter than Shell regular. I don't have a smoke issue due to the DPF fitted. As the Shell V-Power is 2p per litre cheaper than BP at the garages I used - I decided to use that.

Earlier this week, and now with 9500 miles on the clock, I filled up with V-Power and put a double dose of Millers in to test this out. Within 20 miles I felt an improvement of sharper response and better fuel consumption, and now after 250 miles I am on for a 3+ mpg improvement in consumption (my daily driving is the same) and there definitely seems to be more 'poke' from the engine."

Overall I believe it is a case of test it and see. IMHO Millers and Shell V-Power diesel both 'work' it terms of getting better performance/economy; for others maybe not.

For what it is worth, here is the text of a post I did in this thread;- http://briskoda.net/fabia-i/millers-diesel-power-sport-4-a/71245/

.....

Without being rude a derv will only benefit from so much cetane raising, so using a double dose of millars and a supposedly cetane enhanced fuel will probably have a negative effect on the car if any.

The performance gains you attributed to the V-Power fuel and K&N on your RR at JKM above standard were no more than that seen on other TDI's. There have been plenty of PD140 around putting out in the region of 160-170bhp on supermarket or standard derv and totally stock including the air filter.

So what is the point of v-power then? sensible answers please!

IMHO part of it is extra detergents to keep the engine cleaner and part of it is a premium marketing product with a premium price. (Have a read of the undercover economist, it's a very enlightening read).

Also IMHO if in each L of fuel you now have more detergents you have less fuel, so that means less to burn. I guess that it's a compromise as a certain level will get your engine working better as it's cleaner, but too much means less to burn.

in other words; take it for a 'Brisk' drive.

It's also probably costing less, especially if you happen to be on your way to somewhere, and is a lot more enjoyable.

Doesn't have to mean going fast. I generally just keep it in 3rd where otherwise I'd be using 5th gear.

Forgot to mention, I do that on the 140PD Passat, the Octi is petrol.

You don't need any fuel or oil additives these days the oil companys spend millions of pounds on developing oil and fuel!! don't you think if these things were required Mr Shell etc would be selling there own wholesale!!! And it will void your warranty :thumbdwn:
