i have seen in a few websites that the acetone improves mileage & power of the bike. Has anyone used them?? Are there any adverse effects of them??

acetone would be deadly for the engine parts as per me... dont have any experience in this though, has anyone tried this ???

NULON is a gr8 additive/engine oil treatment, but instead of all these things the best option is to go for a fully synth oil like motul 300v...

Nulon is a Teflon based product . Du pont ,who makes Teflon, have adviced against its use in Engine oil as the Oil filter is likely to be clogged.Acetone in "Correct" quantity will definitely help in combustion and cleaning of the Engine internals. The Correct amount to be added vary from vehicle to vehicle.The starting value is 0.50ml for litre of Petrol or diesel and upto 2.5 ml.Excess use of Acetone will bring down the Fuel efficiency.If you Google there are hundreds of pages for and against all these additives. It is best to follow the manufacturers recommendation.
The best mileage is by not having a lead foot for a car and soft acceleration in a two wheeler......But the Single Most Important improvement will be gained by filling at a Good Petrol/Diesel outlet without adulteration, either in the morning or in the late evening when the fuel will be cool and dense.
Adios for now

Shell super unleaded has these additives I guess thats why it gives me a slightly better mileage of about 8% when I fill that.

When i had filled petrol in my bike & was returning i had spotted a few persons who were selling a device which is connected to the spark plug. They were claiming that it would increase the mileage & power of the bike. Is it true?? Has anyone tried it??

you mean the red thing with fuel saver written on it ?
if yes
den its fake

The original device is made by Stromberg and called "Stomberg Power Booster" and is supposed to make the spark high frequency and stronger. here is a link : List of Products .Devices like these have come and gone.They work for some and doesn't for many others.

old thread reloaded

Time to think and research ! any good product suitable for 2 wheelers ?

so can i just put a few drops of my mothers nail polish remover(acetone) and get a slightly better mileage?

Highly debatable. I am no techie but I guess acetone is one form of Octane. So, putting that to increase mileage may sound good but there is no established scientific proof.

I had tried the Lab quality Acetone to know if it really helps...both in my Fuel Injected car, KB100 and ZMA....the result is
1. Very smooth engine .
2. Marginal reduction in knocking when accelerating at low RPM in higher gears...
3. engine starts in lesser cranking of engine..
4. Plugs looked cleaner after 2 to 3 K Kms.
Marginal increase in FE but could not say authentically since there was no
regular use of the vehicle ...but engine did feel smoother..
A word of caution...The ideal amount of Acetone varies from engine to engine...For my car and ZMA it was 1.5ml of Acetone for every Liter of Petrol, and for my KB100 it was 1ml per liter...I do not know the reason for the same...but increasing beyond 1.5ml per liter definitely led to drop in FE in my case.
ACETONE is a paint dissolving agent, so be careful not to spill it on the body paint .

I have also used lab quality acetone and while i got an increase in mileage by 2 or 3 kmpl, i noticed that it was probably because after adding acetone my riding style changed for some reason. Finally i stopped using acetone and adopted a much much saner riding style and result is a consistent increase in mileage by 6kmpl. so point is take your pick.

Also I want to warn people to not use nail polish removing acetone since it is impure & diluted with the one thing you do not want in your petrol i.e. water. The acetone i (& probably psr sir as well) used was AR grade 99.9% pure.

acetone is the most basic ketone group from the hydrocarbon family which has a carbon oxygen double bond

while octanes which are simple long chain hydrocarbons having nothing other than carbon and hydrogen(8 carbon atoms = 18 hydrogen atoms)

so acetone and normal petrol have a vast difference in their chemical composition...only similar thing is they have carbons and hydrogens and they have energy stored in them...(well even human body is made up of carbons and hydrogens :P )

engines are made differently so may be thats why the quantity differs and also wud differ on the 2T or 4T type of engine
how did u arrive on the ideal amount??

d u still regullary use it after seeing the benifits?

i read somewhere adding acetone the less is more...the quantity added varies from 0.8 ml to 2.5 ml per litre(the figures represnting the cut off point between which they work somewhat like a amplifier frequency response graph)

alcohol is added in petrol by the manufacturers(certain countries like brazil use upto 30%) is there any other chemical to improve performance FE etc...

so where can i find pure acetone? and how do u mix it.. directly pour the required amount in the fuel tank or some other way..mixing chemicals are a risky job(if u dont know what u are working with..learnt that in my class 11,12)

So you are an Audio buff ? ..I found out what works for me,... by trial and error in my vehicles,and still use them on/off. In my case I am getting more or less same mileage after a few thousand Kilometers usage,which I think is due to the innards getting cleaned over a period of time..basically the roughness of engine had been subdued and a pleasure to drive.
Alcohol is a no no since the inner iron parts tend to Rust and engine fail sooner than normal..It had been documented and now it is not used as widely as first proposed.

have read about acetone working like charm for few people and infact all of them who used it did agree to things like engine smoothness for it helps fuel vaporize quickly. just a word of caution do not use anything that is consumer good and is acetone based as its diluted that will harm the engine.

go the medical shop or chemist and ask for pure acetone. a 200 ml bottle should be around 40 bucks and yes for petrol it should it around 1ml per litre and diesel 1.5-2.5 ml .

i havent used it yet however a friend did on his old safari and claimed that he never got FE beyonf 10 however this time engine was ultra smooth and for FE of 11.5.


the whole point is using it in the right amount else more acetone will lead to drop in FE.
