Saw this piece in BBC news: www.bbc.co.uk/news/uk-england-13660083 re 4.4% reduction in diesel fuel consumption. Large scale trial by East Midland Trains. This is the stuff: www.internationalfuel.com/ift-labs Seems to be based on a surfacant.

One that worked for me, (and other Ceed owners) is Millers. Some Ceeds with the Euro V spec diesel engine (2010 on model) seem to suffer from injector fouling which causes smokey cold starts, Millers solves the problem.
|
|
Yes, indeed, Millers. I used that in my VAG pre-PD diesels. Seemed to be pretty clean visually - pal following on M62 or similar said no soot, even on full beans.
|
I used Millers in the past though I reckon a premium diesel such as Shell V-Power and BP Ultimate offers the same or greater benefits at a lower cost.
|
I think Millers for diesel has some benefits, particularly on an engine which has done lots of miles without treatment.
There's some film on the web somewhere of 'before' and 'after' dirty and clean injectors.
Fairly convincing, if you accept the common sense proposition that a clean injector is better than a dirty one.
|
when I was in the tuning game, I used to use STP fuel injector petrol additive on many EFI cars,
Some cars were running like they had fuel starvation in a car with a carb for instance,
I'd shove some STP in the tank, whizz it around the block = job done!

That stuff worked pretty remarkably on our Golf. COSHH data sheets from the manufacturer's website say it's ~80-90% paraffin.

Good grief! - how amazing, I wonder what COSHH make of the diesel additives then.

I've got Millers for the Mondeo. As Iffy says, it should show the largest benefits on a high mileage engine that hasn't been treated, so that sounds perfect for my situation. From the first use I noticed a quieter, smoother idle and increased tractability at the lower end of the torque band - I like to toodle around at 5mph below the speed limit and in top gear that's around 1700rpm.
Trip computer economy has increased from 49mpg in March without additive to 53mpg last month with it. I don't know how much of that improvement is down to the switch from winter to summer diesel, increasing familiarity with the car or warmer weather, but if it doesn't need any major engine work in the next 5 years I'll attribute that at least partly to the stuff.
Even at Halfords' price the Millers works out at 2.6p per litre of diesel treated, and the V-Power/Ultimate price premium over standard fuel is a lot more than that. The only downside is that it's a pig to get rid of the smell off your fingers if you spill any.

Dave,
You are not talking out of your posterior.
Combination of all three is my assessment.
Our cars have the same engine and I think warmer weather has the biggest impact.
For me it's 42/43mpg up to 46/47mpg.
That's on a relatively new engine, although it's done nearly 30K now.

Dave, Iffy, Norton, Cheddar.
What sort of "Millers" are you recommending for Diesel engines here? What's the full product name, please?
Thanks.

It is this stuff.

Alanovic,
They changed its name in the last year or two.
Now called Power Ecomax:

Cheers. So you put 50ml per 50 litres of fuel for evermore? It's not just a one off, or twice a year or something.
|
...So you put 50ml per 50 litres of fuel for evermore?...
Some people do.
I use it now and again when I remember.
To start with, I would treat several tanks in a row.
|
|
I usually use it for every third or fourth tank of fuel after it fixed my smoke problem.

Yep, that stuff. Millers Diesel Power Ecomax. I can find it for £10.55 / 500ml on the bay with free economy delivery, but the local Halfords has it on the shelf for £12.99. It's got a pretty accurate dosing measure on the side of the bottle (rather like bottles of Lead Replacement additives for BL cars when 4-star petrol was phased out 18 years ago) and is added at 1ml per litre of diesel.
I'm the first one to be sceptical about these things and cry snake oil, but I researched it online and found a number of individual recommendations on the various Ford, GM and Skoda owners' club forums as well as here and on HJ. Having found personally that the "super" diesel fuels didn't produce benefits in every engine I thought I'd try one bottle in the Mondeo and see how it went. Used it 4 times and so far so good, I'll be buying another when this one's empty. Your mileage may vary.
EDIT: I've just read that post through, it sounds exactly like I'm an advertising troll. I can assure you I'm not :)

If you're keen you can buy it in 5L containers here (price is delivered): tinyurl.com/5rggwzs (Not long ago is was £60).
|
Watch the shelf life if buying in bulk, it's not that long.
I don't know if the stuff does go off, but if it doesn't, why do Millers put a date on?
It's not as if you are going to drink it.

Thats about 250,000 miles worth if you dose every tank, (which I don't). I will be pushing up weeds before then.

Probably good if you run a fleet of trucks or buses. Or an Audi R18 :)

A fuel additive that works. Apparently. - Old Navy
