Has anybody tried Sulnox diesel additive yet?
Found it on an investor evening and the science behind it sounds convincing, enables 8-10% fuel saving and keeps combustion areas clean.
Some big hgv fleets taking it up.
 
8-10% fuel saving is pretty massive really, I wonder why we have now heard of this before? or is it new?
 
£28 for 250ml which will do 5 tankfuls (100l)
Whether it will save its own cost is debatable.
Seems that it only contains natural ingredients, so what, diesel is a natural ingredient.
if it achieves 10% less fuel consumption then that is a saving, much less and it isn't.
 
Actually answering my own question, they dont claim a fuel saving as far as I can see but they do say,

Combined benefits allow consumers to realise an overall reduction in operating costs by up to 10%​

Available on Amazon, just bought one however not doing a trip for 3 weeks to try it out.
Just sounds a better solution to fuel saving than tipping xylene into your tank,
Agree its a bit pricey versus implied benefits but worth a go I thought.

250ml (one bottle) treats 110 gals (500litres) 😀
 
At a guess a cetane booster and the same additives put into the expensive diesel at the pump. Another company claiming benefits on a mystery product

I do know we get better MPG on super diesel and the combustion burns cleaner, along with added lubrication and injector cleaning. The cost difference as of last year against the higher mpg was effectively cost neutral, as in the same mileage per pound spent. The added benefits of the additives would in theory give a maintenance cost benefit over the lifetime of the vehicle. 10%? who knows, but it might be

Will I invest in a fuel additive that claims the same over just buying better diesel? Not at £25 a go, that would buy a lot more super diesel at the cost difference

If a petroleum company could buy this sort of additive at wholesale prices and (easily) inject it during the final blending process And save that amount of fuel, I wonder why nobody has done it?? :whistle2: How many ppm is that? 0.5??
I‘m still calling snake oil on this

The best independent review I can find is from the Morning Star which quotes a small test of 4000 litres and produces “no harm” :rofl: A marine diesel needs to run for days to show damage caused by harmful compounds such as Catfines, Vanadium, chemical contamination etc.

I see that as a result of this trial the shares were “untraded at 0.19”

I think what they are claiming is an overall 10% reduction in operating costs incrementally achieved over various areas (see below). They’re not claiming a 10% increase in fuel economy. Any such reduction would be seen over a period of years, certainly not from one trip.

I'd been using archoil 2000 and not had any issues.

Stopped using it as it stinks and my daughter's needed to go in the van, also didn't do the long motorway journey this particular month and now the dpf light is on!!

Confidence perhaps??
 
I used to go on a Ford forum, the contributors advocated the use of 2 stroke oil mixed in the diesel. As it burns hotter therefore cleaning engine.
Is this the same stuff different name?

I've never suffered from "worn fuel pumps, injectors or engine parts corrosion" and my last two diesel cars both went over 200k miles ? What I do suffer from occasionally now is egr valve issues putting the eml on, two tankfulls with STP or similar added usually clears the problem for a few months. I tried using Dipetane for a few fill ups (maybe heard about it on here ?) but that never cleared the eml.
I have blanked off the egr in previous cars, but this one would need a software rewrite and that's not something I've looked into yet.
 
So it is a substance that takes water out of the fuel somehow. There's plenty of products that do that - just pop in to a chandlery and you'll see things like Fuel Set which I used to use on the boat to keep the dreaded diesel bug at bay and still use in the car when I remember to. Half the price of SulNox.

Cetane boosters often work quite well on old diesels making them run smoother but I can't really see any benefit for a modern low mileage diesel where the combustion is fully electronically controlled by the ECU.

I really would like to see scientific, peer reviewed evidence of all these claims. I was in the fuel testing business for about 32 years and fuel companies spend billions between them trying to establish the above.

As I said before, a short test of 4000 litres in a marine diesel which is designed to run for 30 years almost constant use without rebuild concluding “no harm” :rofl: is simply laughable. If people want to waste their money on this sort of product added in chemically insignificant quantities then it is their choice. I am not talking about branded cetane and octane improvers with detergents, by the way, as they are scientifically proven
 
Anyone remember the magnets for putting around petrol fuel lines.
Supposed to align the fuel molecules to improve MPG.....not!
What a load of cobblers.
I do have a boxed set I found in a car I bought at the time.
Not worth the cost of two tie-wraps to fit them.

Do you remember the water/steam injection?
 
When I took over my new to motorhome it had been left a year with practically no fuel. Filled it up but after a while, and a full service, started to run unevenly. A bottle of silver hook diesel cleaner gold seems to have cured the problem, possibly clogged injector.
I wouldn't bother to use any of these things regularly. I used to bung in some redex when it was on offer at Wilco though.
 
At £5.60p per tank, why not just put a premium diesel in every couple or three tanks? Much cheaper and nothing to tip into the tank! And you don't have to remember where you put it! (or is that just me?)Shell V-Power is 10p per litre dearer at our Shell station, 70 ltrs every third tank and it would be £7 divided by three, £2.33 a tank. And you could leave it longer if you use non supermarket fuels normally.
I have never understood why people always fall for the "Snake Oil" pitches from companies with a vested interest.
