Millers Diesel Power Ecomax
Discussion
Anyone ever used this stuff in their diesel? Seems to have decent reviews on halfords and a few other forums. What do you guys reckon?

I'll bite - just to re-invigorate the thread.
It's good, it works at least from a detergent effect perspective, and is the only reasonable value additive I've used that has actually felt the difference on my old Lexus IS. Try it. I would temper fuel saving expectations though.
If anyone can prove any of the fuel consumption claims and performance claims data of Top brand (proper proof please) then I'm all ears. I believe almost all the performance claims are effusive and not replicated in real world scenarios. A 2.5% difference in fuel density within the fuel spec may make more difference.
With regards to the alternatives:
1. Cheap base fuel (Asda/Morrisons) is not really going to help any car you won. It meets spec, but you can drive a cart and horses through EN 590 or EN 228. Does not keep clean.
2. Shell V-Power/ Ultimate - good get clean/keep clean solution - 12.4 pence per litre average premium.
3. Supermarket good/other fuel + Millers Ecomax = 2.4 pence per litre on top of fuel cost if at 1000ppm or 50ml per 50 litres. Great get clean/keep clean solution. Fraction of the cost.
Tell me i'm wrong please. But why would I not go for reasonable low cost base fuel (same stuff as uber premium, same spec, same tank at the terminal) with my own additive as opposed to overpriced fuel with oil major additive rate,

Strange, my car gets better fuel economy running Asda/Morrisons than shell, maybe Audi design their cars to run on crap.1. Cheap base fuel (Asda/Morrisons) is not really going to help any car you won. It meets spec, but you can drive a cart and horses through EN 590 or EN 228. Does not keep clean.

Are you suggesting Asda or Morrisons fuel is not as good quality as, for example, Sainsburys or Waitrose fuel?
I think it's reasonably common knowledge within this forum about the additive inclusion within Tesco. Sainsbury's, BP, Esso, Shell etc fuels. I do not believe Morrisons or Asda make any claim about additives and a number of brands don't shout too loudly either. Make of that what you will - and it's only part of the quality story.
I was not aware that Waitrose did fuel in their own brand, it appears linked with Shell vis-à-vis M&S with BP. If you think one fuel is any different to the next just wait at the exit gate to the Terminal at Thames Navigator or another non oil major terminal, and see what tankers are coming out. It's all the same save for additive rates and own company policy and quality procedures.
Kind of irrelevant what sort of base fuel one uses I suggest as long as it's reasonable. Pick a good cheap fuel, add your own detergent additive of choice, and decide if £5-6 a tank is better off in your wallet.

Understand that, perhaps one for the chemists out there but does efficacy diminish over time in solution? Anyone had any negative side effects due to overdose?
My lexus 220d started puffing a bit of white smoke (with a hesitation on the throttle) after time spent idling in traffic on M25, but was unsure if this was the effect of additive, or the car, or crappy base fuel from oil major station in Europe. Issue has now gone away.

It says on the Miller diesel bottle, that you can use up to 2 x the amount recommended for extra power / mpg . . . make of that what you will(doesn't say the same on the petrol additive bottle)
I've used it in the past and whilst I've never actually measured if the car is doing better on mpg, I'm more than happy that it's cleaning and likely running at a similar cetane rating than "super" diesel.
The price of the "super" diesel is just ridiculous now. I was running on the super/supreme diesels, not anymore.
It's far more cost effective to put in regular diesel and add millers to it.
It also smells very similar to the super diesels when you open the cap to top up.

Holy thread revival
Anyone any more recent experience with this or the petrol additive? Seems that two of the major petrol supermarket sellers have reduced prices to less than £1 a litre, I might visit them and with the addition of this might be worthwhile
There is another thread on here somewhere listing the alternatives...but basically it was to show that the active ingredient (2EHN) is available in bigger quantities for less.Anyone any more recent experience with this or the petrol additive?

Something like https://smile.amazon.co.uk/dp/B07BMP6DGM/ is what I use.

Which is the same price as Opie Oils sell the Millers stuff for . . . Something like https://smile.amazon.co.uk/dp/B07BMP6DGM/ is what I use.
I've been using Millers Ecomax for years and over 200k miles in an older diesel engine. Also add a measure of two stroke oil to every tankful, to help out the Bosch VP44 pump and keep the injectors quiet. Noticed a marked improvement in fuel economy, slightly improved pickup, and very little if any black smoke from the exhaust. MoT man always comments on how clean the emissions are for a 2002 car with 280k on the clock. Is it the Ecomax, two stroke, or good maintenance? Who knows. I think it's good stuff, and go through about a gallon a year.
