Yep, it's true, well with a wee bit of cheating!!


Added this-


http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_895221_langId_-1_categoryId_255221


To almost a full tank & set off on a journey of 88 miles, from Barnsley to Bridlington. Two adults, two teenagers & a 6 year old on board. To my amazement, and never achieved before I averaged 45.2 mpg!!!!!!!!!!! Being totally honest here too, I wasn't particularly trying either! Yes it was a steady run but a run that kept on pace with the rest of the traffic along the whole route. NEVER have I achieved those figures before even with just myself on board.


Dropped a little on the way back to approx 44 mpg.


On the way back up to Scotland & with the tank refilled (but no more additive) I was again achieving 44 mpg average but after 78 miles I had a regen!!
and this dropped to 35.7 mpg. The regen lasted approx 18 minutes but another 100 miles later it had still recovered to 40.3 mpg!!




We'll see how it goes.

Hi,So does this stuff work, the comments are mixed on Halford's website and are there any downsides?

Well it certainly works on a improved economy basis!



It's too early to tell regarding the DPF. I added it after a failed regen & so I would imagine that the car is then "programmed" to complete that regen regardless- as it did after another failed attempt 199 miles later then completed at the third attempt 78 miles later again.


I will be monitoring the results as I have a record of all my regens for the last 2500 miles.

Hi Going to Portsmouth for the ferry in a couple of weeks, I think I will give it a try as it is a 240 mile tow and I know that I normally get 25mpg so could be a good test.

I actually went to buy this -

http://www.halfords.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10001&langId=-1&productId=370465&catalogId=10151


BUT, with the car doing a regen after 190 miles of 100% motorway driving I bought the Wynnes product too & used that instead. I haven't yet used the Millers product.


Both were bought and are cheaper at Motosave by the way (http://www.wilcodirect.co.uk/category/diesel-additives ), just using Halfords for the links.




Give it a go, there's nothing to lose. I wasn't expecting such a jump in economy with the DPF cleaner (although it does state that it increases economy).

Hi,Have I got this right, you used the dpf cleaner first then the Millers addative in the next tank?

NO NO!! I could have wrote it better. I ONLY used the Wynnes DPF cleaner, I originally went for the Millers after reading rave reviews & bought some while there BUT....... the Millers remains unopened for a later date!!





Earlier post now edited to avoid confusion.

Definitely sounds impressive, but even at £7.99 it is supposed to be added every 1,000 miles. On an average of 10-12,000 miles a year would cost £80-100 a year.
Agreed cheaper than an extra oil and filter change, but why not try the jlm that recommends every 6,000 miles or £40 per 12,000 miles

Yep, looked into the JLM. To be honest, it's just a bit of a trial & these two were there to grab off the shelf.


It would be nice if the Wynnes did help with fewer regens but I'll certainly not be holding my breath on that one!! Time will tell & if indeed any one of these products did reduce regens then any of them would be a bargain!

Hi Dilligaf,
What's jlm?
Hiya Dave47 jlm is a brand name. They do different fuel additives, , the newest being dpf cleaner. They state that it will help with the regens (burning the soot at lower temperatures. Also claim improved mpg and only needs to be added every 6,000 miles.

Hrm ... expensive, but I suppose in the long run not so bad.

I regularly use the Wynn's additive (purple bottle) which I bought on Ebay from Autosessive, as their multi-buy of 5 bottles worked out at £5.65 each. I've since decided to go with the professional range (black bottle) as it is meant to drop the burn-off temperature/engine rev relationship a little more. It's more expensive than the normal stuff but Autosessive (ebay) have it at about £10 per bottle when bought as a multi-buy.

I've yet to achieve those figures, having got 35 mpg on a run down to Manchester but, I was booting it (85-90) with the Aircon full on, so 'my bad' as they say!

Hopefully, with this stuff and my bluefin tweak I shall see some better MPG figures being returned, if only I can resist using the bigger BHP and Torque to burn off the boy racers at the traffic lights - I should know better at my age too!

Anyway, it would seem reasonable MPG figures can be achieved, so well played Sir!

Do you have the Bluefin fitted now then Laz? Any chance of a review/write up mate?



Have you seen any difference in your regens since using the Wynnes &/or Bluefin?

So is this stuff suppose to reduce the number of regens by lowering the temperature at which the soot is burnt off ?
Just interested as you had a regen later in the journey.


I use the Millers which raises the cetane level of diesel thus it burns hotter so has the same effect but the opposite way round. Similar to using one of the more expensive fuels that the likes of Shell etc sell.
I have used it in my previous Antara and the Discovery before that.
In each case the engine runs smoother and more quiet.
I drop 75ml into every other tank full, mainly because i use supermarket fuels.


I also guess those MPG figures are from a manual gearbox version ?
At what point do you reset the BC to get your consumption figures ?


Interested to see a comparison.

Yes the car did do a regen on the way back BUT...... it had started & failed to complete THIS regen TWICE BEFORE the additive was introduced. So, I have to assume that the car would have completed this regen regardless anyway.


The car is a manual yes.


The BC was reset at the set off of each journey, so the 45mpg trip was reset on my mums drive. The 44mpg drive back up to Scotland was reset at the fuel station just before setting off.


They are "genuine" figures. Not achieved by resetting the BC "on route" in perfect conditions for a set period.



It will be interesting to see when I get the next couple of regens to determine whether or not this additive has made any difference or not in regard to soot deposits.

Thank you for the comprehensive reply.
