After lots of reading around about pump diesel, standard v premium, fuel quality, ideal Cetane levels etc, I've ordered some of this.

Anyone have experience of using this?

I've been using the Archoil Ar6200(similar to Ar6800) for 12 months. Before that I used millers for 10 years on same car.

I normally use Asda diesel with 5ml of Ar6200 per full tank and find it the best fuel set up for my car. Runs better than using v power, less smoke better throttle response ect.

Always difficult to scientifically prove gains but from the seat of my pants in a car I've done 134k miles in i'd stick my neck out and say it's great stuff and works far better than V power and similar. Some will disagree but I know what works for me in my 11 year pd 130 engine.

Wow, it's quite a lot of money even when buying 5 litres (£125)

£125 Is nothing to you Jason lol!

5 litres would be good for around 250,000 miles in a 1.9 Pd engine.

I bought a 500ml bottle.

You can try some later this week if you want?

I'll start with 50ml per tank using Shell Fuel Save (it's round the corner from Asda so they always match the price )

sounds like bull****. 

Millers is less and TBH I think somebody in the sales and marketing world deserves a prize for people who are buying that.

sounds like bull****.

Do some reading up on Cetane levels in UK diesel, available v optimal.

It probably is bull but my car runs better on it so i'm happy.

I have a degree in Chemistry/Molecular Physics and I have researched this in depth

 

Higher Cetane values may improve mechanical running in some combustion engines but does not correlate to better performance

 

So to market a Fuel as a combustion engine performance enhancer is giving false hope to the 1000's of diesel owners

 

I suggest you do lots of reading yourself buddy

I have and I'm not purchasing it as a performance enhancer which why I referred to the Cetane levels. With a degree in Chemistry/Molecular physics you must know that the Cetane rating at the pump in the UK is 51. However the optimum number for combustion is 58, anything above that is pointless. This additive brings it up to optimum Cetane rating and by doing so, allows for optimum combustion, cleaner and more efficient.

Hope that makes sense, me being an uneducated elk

Actually EN590 specifies a minimum cetane number of 51, there is no maximum value prescribed. Therefore the fuel you buy could be higher and by adding some kind of additive you could easily push it over 58.

The latest Which test only found two fuels available at the pump over 51 at 52 in their last test, so the likely hood is slim if staying within the prescribed measurements of fuel and additive.

Interesting, got a link, I can't find anything on it.

Which did test diesel additives and the best they got was a 1.7% improvement in fuel consumption, performance difference was negligible.

It's in the magazine, I'll try and take a pic of it, again, it's not about performance improvement in terms of power but efficiency in combustion, the engine is smoother, maybe it's all in my head, but even the missus commented on the car running smoothly.

It should turn up on line later then.

Also when which tested fuel additives the biggest increase in cetane number was 3.5 so you would still need to add twice the stated amount to achieve the optimal effect. The worst performer only increased it by 1.2.

They didn't test the Archoil though, unlike the ones tested it doesn't make outrages claims, that's one of the reasons I chose it.

Here's the tech sheet

It actually claims very little. The paperwork for it runs to one page and the Amazon description is just a copy and paste job. It does claim to improve performance and an increase of "up to 8" increase in cetane number. What this means is that the manufacturers are claiming it doesn't increase it more than 8. 1 isn't more than 8.

The active ingredient is 2-EHN which is the standard cetane improver. You can by 2-EHN for £95 per litre, therefore you can assume that AR6800 is probably contains something like 10% 2-EHN. The blurb for it also gives two dosing options, which infers the higher dose is required for maximum cetane number improvement, or that a double dose will still be less than 8 improvement in cetane number.

I have tried duel additives in the past and saw no difference in fuel consumption over a 6 month period compared to another similar period not using an additive. I did seem to see a reduction in sootiness but that was not exactly a quantitative assessment.

Little more info on the website:

AR6800 Fuel Modification Complex was developed to address the shortcomings in liquid carbon based fuels. AR6800!utilizes the principle of catalysis for its fuel modification properties but is also a demulsifier, cleaner and fuel system protector. It successfully increases available combustion BTU through the use of a revolutionary fuel modification technology.

AR6800 increases the surface area of fuel droplets to increase the burn rate resulting in a more efficient use of fuel. AR6800 is engineered to lower the ignition point of fuel as much as 400º F therefore modifying the burn at a lower temperature utilizing more BTU’s and providing more energy during the combustion process. This helps eliminate black smoke with a major reduction in carbon due to a much higher burn rate. A decrease in fuel usage is realized with added horsepower and torque.

AR6800 has been extensively tested in the field using the EPA CMB test (the most accurate EPA test for MPG) and averaging an 8% improvement in economy. It can be used in any carbon fuel including bunker fuel, bio-fuel, pump diesel/petrol and will help maintain storage fuel integrity. It is successfully used worldwide in every type of application including consumer vehicles, fleets, power plants, ships, mining equipment and more. AR6800 is the only fuel treatment needed to address the major limitations inherent in fuel.

I found this link which points out the 2-EHN is a solvent which reduces the lubricity of the fuel, so more lubricant additives are required to counteract it. Which probably explains what makes up the rest of the contents of the bottle.

Also the fuel improvement measured above appears to be done in the US where I believe cetane levels are significantly lower than in the EU.

As I doubt there is a linear relationship between cetane number and "efficiency" you may see very small differences with EU fuel compared to US fuel.

The cetane rating on fuels is an average and can fall or rise. Even in certain premium fuels

 

Possibly more efficient. Possibly more total combustion. The word possibly being the keyword here

 

A large percentage of the times the tests were negligible and unless you have very strict test conditions you are just guessing

 

:no:
