I’ve been sent links to www.dipetane.net.. According to the website you add dipetane to your petrol or diesel and you get a 10-17percent efficiency increase and reduced greenhouse gas emissions.
According to Wikipedia* it’s a fuel enhancer that improves the quality of combustion of any liquid fuel and it reduces emissions of CO2 up to 25%, CO up to 9.5%, NOx from 28.8% and SOx from 19.9%.
So why aren’t we all using it?

update 9am, next day
* Apparently this link was to a Wiki user page rather than the Wiki proper and the information was ‘commercial content’ and so John Quiggin has had the information removed, so the link no longer works, see comments from John below. And I’m wondering whether the ‘commercial content’, as repeated in this blog post, is factually correct or not?
Jennifer Marohasy BSc PhD is a critical thinker with expertise in the scientific method.
This looked interesting enough to follow up, but if you look at the link you’ll see it’s a user page, not a Wikipedia article, and the only source is a marketing website. Material like this would be deleted immediately from Wikipedia proper, and even posting it on a user page is dubious practice.
There are some fuel enhancers that are reputed to clean out the sludge that accumulates in diesel systems – I tried it an old tractor of mine and it blew clouds of black smoke then ran clear, first time for years. I then added it to stored fuel and it certainly appears to make the engines run more cleanly.
Bio fuels ie bio diesel are also said to clean out systems and they warn that you may have change blocked filters when first using them.
There is another ‘extender’ where they blend LPG into fuel – greater power for same fuel – I’ve seen them on 4WDs

I pointed out this page to an administrator, and the commercial content has now been removed. Wikipedia is still an evolving system.
Hey Rog – I’ve got an old diesel that blows dirty smoke ( despite new filters – fuel and air).
What enhancer did you use?
I did use the one by Chemtech, not that I have any preference more that it was the one available. Basically it is a biocide, it breaks down growths that can accumulate. You dont use much, ratio 1:4,000.
With diesels, if they are run often and long and get hot they tend to have less problems with growth.
Some say they have problems with new low sulphur diesels and loss of lubrication – seals leaking in injector pumps etc. BP say that they have overcome this by add lubricant to their Ultra Low Sulpher Fuel.
This mob also claim to increase efficiency with an inline catalyst

and this mob say its unscientific, untested and all crap

I wonder if WOSAT Distribution LLC is a sponsor of the IPA. I wonder if Jennifer cares whether or not the information is factually correct.
Coby, the WOSAT are not a sponsor of this blog site, I doubt they are a sponsor of the IPA. You have suggested that I post misleading information because people pay me. I’m becoming tired of your nasty accusations and request an apology.
Well, to be fair, I did not suggest you believed the information to be incorrect, just wondered if it mattered to you one way or another.
But, I will take your word for it that no one paid you for this advertisment and therefore do apologize.
I don’t recall any previous nasty accusations, though…
Coby, I stated in the update this morning (see above), after John Quiggin pointed out that what I thought was a link to Wikipedia was in fact a link to a Wikipedia user page that:
“And I’m wondering whether the ‘commercial content’, as repeated in this blog post, is factually correct or not?”
So can you, or someone else tell me whether or not: it … reduces emissions of CO2 up to 25%, CO up to 9.5%, NOx from 28.8% and SOx from 19.9%?
You gotta watch your engine seals, esp if old or dirty before using such additives or even biodiesel (some biodiesels can run more efficiently than standard diesel).
Keeping yr engine running in good nick and good driving techniques reduce GHGs too Jennifer.
What would you know about diesels pixie? Talk about ill informed..
rog – actually pinxi is correct. Biodiesel can affect rubber seals in certain diesel engines. It is recommended that all such be replaced with ones that are compatible with biodiesel before using it.
It is also a lot cleaner running.
Only old engines Ender, and those that use rubber hoses and seals, modern motors are not affected by bio-diesel.
I’ve used additives in old Perkins without any issues.
It seems that the recommended rate for the additive is about 0.5% by volume. I cannot do any sums that would indicate a 25% reduction in CO2 emissions is achievable or even a fraction of that (try 0.25%). However, maybe I have missed something.
Quantam last night featured a story on driving behaviour ( not by any means a rigorous experiment) which seems to suggest that staying put in heavy traffic as opposed to constantly changing lanes results in much lower fuel use and consequently lower CO2 emmissions.
The other lane does always seem to be moving faster……
Dont you worry yrself rog, I well know the difference between my head and my o-ring
Its encouraging to hear that you know your big end from your manifold pinxie.
Yes Jim, I thought that Quantam was intetesting. One thing they said was, fuel consumption was increased by 400% in the more aggressively driven car.
So my wife’s little thing could jump from 6.9 L/100Km, to 27.6 L/100Km, if I jump in. In fact, I get slightly better economy, as I don’t slow down as much, or as often, requiring power to accelerate again.
Me thinks that the ABC has moved a political program producer to Quantam, as the subjects had more political correctness than science in the treatment of the subjects.
Hello Jennifer,
We do not know each other but I am with WOSAT and I would like to respond to your question of whether or not Dipetane reduces emissions as Wikipedia stated.
And to the site admin, I hope I have posted within your rules! 😉
I was just doing research and found this link on Dipetane, forgive me if I have done anything to offend.
Here is the research, completed over a 10 year period:
http://dipetane.net/html/research_fuel_emissions.html
These are the stats:
# Dipetane lowers – Nitrous Oxides ( NOx ) 35% or more.
# Dipetane lowers – Carbon Dioxide 23% or more.
# Dipetane lowers – Carbon Monoxide 9% or more.
# Dipetane lowers – Particulates ( Smoke ) 61% or more.
# Dipetane fuel technology is safe for all engines.
Here is what Coca-Cola Ireland had to say about it:
Coca Cola Bottlers of Ireland – Report on Dipetane Performance In 1990, Pat wrote a letter of experience describing his use of Dipetane and what benefits he found. Over a 9 month period Coke found a 17% improvement in fuel economy.

We welcome new distributors.
The thing about Dipetane is that it is completely different. It is not a detergent trying to ‘wash out’ carbons. It actually burns the carbon at the point of combustion. That’s why it reduces your carbons and in doing so increases efficiency on mileage. It is completely different to adding one of a hundred ‘detergent’ products to your fuel.
Just came across your blog. As a manufacturer and blender of Dipetane it always is of interest to see the dialogue that takes place when the discussion turns to fuel technology. While most folks can speak from first hand end user experience, it is the scientist, fleet manager and energy expert that can validate a product via quantitative analysis. Few folks out there have knowledge of TMC II testing or know what the J1321 test is about. Thus one needs to look at the source of information and both the independent 3rd party testing and live fleet data to truly validate a this type of product.In the case of Dipetane, 18 years of history seeks volumes.
Why is it not a brand that everyone know? Simple economics is the reason. Until US cost of fuel reached record levels, the ROI on Dipetane did not excite bulk commercial users. Today, most corporatins are under sever margin pressure due operational and transportations costs that have skyrocketed because of the increased cost of fuel.
While there is a recent level of complacency due to a recent slight decline in the cost of fuel, most smart fleet operators are preparing for the next round of high energy costs. Many are starting to implement Dipetane as part of their program.
If you would like to try some Dipetane, let me know..I’ll send you a sample.
i would love to try some dipetane, but dont know were to get it.
Same here. I heard a friend talking about it, but he’s and OTR Trucker, and gets it when he can find it. I don’t know where down here in Mississippi to buy it. Any suggestions? What about prices?
used dipetane for three month 3 mpg better in my diesel pickup. my friend also get about the same results
