Dipetaine and emmissions ?

Barr

Hi
Following on from another thread I'm just wondering has anyone actually used this product and more importantly does it work ?

Also how much of it did you use ?

Thanks

yes it works well on my car, cheap too.

How much of it did you have to use ?, friend has a car where the CO2 is running at .71 and it should be .3 at high idle so was exploring this option.

What kind of figures did you have pre/post NCT.

More detail would be great

Due to the high duration of the cam, my engines HC's were off the clock somthing like 1300PPM, the car stank of petrol at idle, after diptane it doesnt stink of petrol.

I havnt bothered to nct the car(yes its illegal) because its been off the road since may getting lots of work done. so ive no definative figure on the emmisions post diptane.

What i can say is, its burning the petrol more complete, its also easier on the petrol.

mine failed due to the engine being FAR from standerd spec, if your car is standard and cant pass emmissions, id be looking at the engine before diptane TBH.

i think you use one graduation to a 40 litres of petrol, i think 1 graduation is 10mm(cant remember as i havnt had the car out since may)

It gets rave reviews for reducing emissions on cars that have failed NCTs with that issue. I've tried it in my last diesel and found a reduction in visible smoke but no improvement in mpg (and I wanted to believe that it worked). It raised the idle speed slightly in my carb engined Volvo 245.

Personally, I wouldn't use it in a car with a particulate filter as those filters are very sensitive to exhaust content and can be damaged by the use of oil or additives not designed for them.

I've looked at the official test results for Dipetaine and notice that they don't include common rail diesels. I suspect that such additives give more dramatic test results in the older, more inefficient diesels.

If you have a car with a particulate filter then I suggest that you use an additive that's specifically designed for that setup e.g. Millers Power Sport 4.

Just my opinion :rolleyes:

CO problems are adjustable... get a decent mechanic.

HC problems are a different issue, they may be adjustable or could be down to wear - ie no amount of adjustment will cure it.

The other issue here is that with older cars, make sure the NCT centre has made proper allowances for the increased tolerances... a common problem.

It works but it isn't a very agressive treatment which is good so to get best results, you should use it periodically or regularly enough. Coca Cola use it permanently in their commercial fleet and add it to their fuel storage tanks in their depot so every truck has diptaine in the fuel... They claim it cuts their fuel bill...

The mechanic says the CAT needs replacing , so theres no real adjsutments that can be made

high HC will kill a cat in no time....

Its brilliant i used it for my nct it had no cat convertor in at all and passed i put in half the bottle bout 3days before test with half a tank of petrol and the 2nd half the night before and make sure you have as little petrol in the car for the nct in order to have the dipetaine as concentrated as possible. didnt notice much on mpg if anything more but i was driving it hard for them few days before the nct.

Lol, the link is spelt wrong!

The mix is 200:1 for people asking.

Damn you! www.dipetane.ie

Acetone.

Been doing the rounds for ages.

Snakeoil IMHO.

PS available from your local fibreglass fabricator.

Amazing results? out of curiosity I tried a dose in a Landrover with no noticeable results.

Sounds like the magnets on your fuel line rubbish that did the rounds 30 years ago.

What has acetone got to do with this thread? Have you ever seen Dipetane, its a a quite thick oil, its not acetone.

Acetone has some performance merits, but the damage to engines would have come out by now if thats all that Dipetane was.

Matt, with the greatest respect, I have read the various websites etc and their claims. I have not yet come across a source of information on this subject that can offer independent, academically accepted evidence of their claims.

As for Acetone, its long been a myth that adding acetone to your tank has had miraculous effects on MPG.

Based on current research...Snakeoil is my verdict.

What are your experiences using this product?

Ive found a noticable drop in smoke along with a 50km'ish increase (620 -> 670km) in range on my diesel. It doesnt seem to have much (measurable) benefit on the turbo petrol motor we have, though its run on E5, which itself could be considered a cleaning agent. Ignoring the "how", the result on one of the cars is less smoke, which generally is caused by carbon build up / excess fuel burn. If it reduces carbon deposits, it stands to reason its good for the engine, good for economy and better for the envirionment, which is all they claim it to be.

I try to keep an open mind and make my own assessments. Instead of looking for lab tests (IRC they do have some testing publicsed) you could just test it... Debunking products that you could easily test yourself but simply havent bothered is a dangerous shortsight. If we all had that approach no company could ever introduce us to new technologies, we would be stubbornly stuck in our skepticism for eternity.

Again, it has nothing (at all) to do with acetone, Im just wondering why you have brought it up twice now?

Out of interest did you have an emissions test done beforehand that you figured you needed the Dipetane? While I may occasionally defend the product, I wouldnt have thought it could so drastically effect the fuel that it makes up for the total absence of a Cat. How close was it to failing on the NCT result? What car/engine?

Prolly shouldnt run it in such concentrations either.. its probably not directly combustible, ie its not a fuel substitute!

Gotcha back! Dipetane is not 'quite thick', it flows freely. Not like oil at all.

I have a 5l tub right here!
I would describe it as "quite thick" relative to Acetone (ie nail polish remover) and it is very much oily, similar to Olive (Veg) Oil in consistancy, which also could be said to flow freely.
