Mind you all the above was with just 1 ml per liter, half that of what finetuning initially tried and recommended. I only had a small bottle of acetone and hence didn't want to use up all of it at once, on top of being cautious. I may try the recommended 2 ml per liter after a while and see what difference that would make.

However, anyone know where I can get BIG bottles of pure acetone? I got this small dinky bottle from a pharmacy (pure) and it's already almost half over with just the first fill up....

Dear vezj420,

Your initial observation is correct............you can safely add 2.5 ml per liter as 1 ml is too less for your icon I think.......using such tiny amount has no adverse effect.....with 2.5 ml you will get yet good response & power.....do check your FE with this......

Acetone improves the combustion & hence gives more power......improving the combustion is such a ignored criteria..........

Also its so much advisable to use 2T oil in the ratio of 2ml per liter........I initially started with 1ml 2T.........it gives remarkable smoothness in driving & adds power too......

You can find 500 ml pure acetone bottle from any chemical market.........its an industrial solvent easily available.......

Enjoy..............

Using it in gypsy and kinetic honda for the past 4 months. its amazing, but experimenting with various vehicles i have come to the conclusion that acetone rocks in older gen cars and twowheelers, the carb versions of the former and two stroke versions of the latter.the new gen vehicles show some difference but not as awesome or as acute as the older ones. i'm hooked since the last 4 months!!

Dear Stage3Monster,

You are absolutely right in your observation.......the design & fuel delivery of old generation cars were not efficient to fully vapourise the fuel particles hence we get good boost when we add acetone as its basically fuel vapouriser additive..........but with new fuel injected vehicles even it differes from same model of vehicles as condition of every vehicle is so different....however benefit is there as yet any can company is not able to fully vapourise fuel just before ignition........

So I assume till technology invented to take care of this peculier aspect of fuel,acetone will keep working.........

Enjoy........

Question one : Companies spend millions of dollar to increase fuel economy by 5%. So how come something which claims 15% increase in FE with increase in power has No Scientific study backing it?
Question two : Mythbusters(Season 3, Episode 16) did a proper test using fuel measuring etc., They did not find any improvement.
Question three : Can you publish FE data over 3 consecutive tankfulls with acetone and without acetone(3 each) with all other factors remaining same?

If I can find pure acetone I dont mind doing the tests myself since diesel already has high percentage of aromatics and I dont think .25% more aromatics will make any difference(harmful effects). Atmost it will clear deposits due to bad fuel.

But acetone is highly corrosive on Plastic, so I am not too sure about effect on fuel lines in long run(though .25% is no big deal)

[finetuning]

I think its better to try first as very tiny amount is not at all harmful.....feel the difference in either way then allow our mind to think in either directions based on direct experience.........nothing pays more then direct experience.....plastic bottles carrying acetone are polypropylene & not normal plastics....I think our fuel lines are not normal plastics so nothing to worry.....

In diesel it plays great role of reducing black emission especially in tata cars apart from improving FE & moderate power.....pure grade is easily available across chemist shops......

there is a company in bangalore that makes pure acetone. but minimum purchase quantity is 5 litres.

[Stage3Monster]

ok seriously, no one is gonna give you a warranty to try this. you will either try it or opt not to . so plz stop asking us to do a scientific reasearch on this. Finetuning, u rock man, thanks heaps for digging such a thing. i was brave enough to try it and see good results. i guess some people will always crib about this and that, and never try anything no matter what! acetone is awesome! 'nuff said!

[finetuning]

With Acetone stuff I would say that instead of thinking why big oil companied not utilising this if we think from consumer point of view then picture is different.......its after all we consumers at low end getting benefit with such simple yet effective thing......so think in this way that why such benefit is not passed on to us?.....Why we need to look & think from the point of view of manufacturer?....If we look at any events & happenings from another angle then it looks so different.........

Enjoy.....

I am not sure why companies/sceintific studies are not backing actone-theories(aprt from user's stories over web).

Slightly off-topic:

IMHO, But most of the company's do have SOME policies that are detrimental to environment,end-consumer benefit -- most of these have policies that are financially good for company(not for end-consumer). Yes, comapnies need profits for survival, but it should be win-win situation(for company and consumer).

Neither I do not understand government apathy towards such desi-inventors ? Use of somendersingh's in all of our petrol engine would definitely increase all petrol cars FE by 10-15% -- imagine how much benfit to oil-imports and end-consumer and enviroment. One of American magazine wrote that if they use his invention, 25% gulf-imports can be reduced.

For Example:
* Somender Singh's Invention/Patent. Even ARAI proved the benefits and saving is approx. 10-25% FE with lower-band torque. Why no manufacturer uses the technolgy ? Which force is stopping them to use in new/old cars -- ego-factor/any-other-ulterior-motives ?

* Why can't Govt. enforce all indian-car manufactuers EITHER to put grooves in all petrol engines(old/new at workshop/factory) OR increase FE/torque by 15-25% with less than 10,000Rs(with their great so-called R&D teams).

* There is Mr. Gopalakrishnan from in Madras(from Hydrodrive). He got a patent on reducing the emissions/increased-FE by passing liquid-fuel(diesel/petrol) thru micowave guide. Why we are still using the cat-convertors even with that invention ?

In Delhi/NCR pure acetone is available at all leading chemists in 100 ml & 400 ml bottles. I pick-up my supply from BL & Co, Yusuf Sarai, New Delhi.

Hey Guys, all this use of acetone in petrol by so many folks is definitely a big deterrent for anyone every considering in buying a second hand car.
Don't think I would ever buy a second hand car knowing that the previous owner could have tried such experiments.

Honestly speaking, the slight gain that's claimed by most really does not seem worth the extra risk in a fuel line rupture and so on..

Just my humble opinion

[vezj420]

Acetone is corrosive on SOME plastics....not all. the 400 ml bottle itself is a plastic one!

Any chemists here care to enlighten us?

Please go through the earlier posts the topic on wether or not acetone damages plastic has been discussed.

Dear autoenthusiast,

The discussion goes on & on & on.....

One thing I can say that apart from any scientific testing if we feel changes in driving in a better way then also such tiny stuff is useful at no extra cost........I tested in my old car but thereafter I drove it as if its not added to remove any factor of careful driving for FE purpose...so FE gain is definitely there as we cant drive consistantly keeping FE in mind......I dont wish to compare this with any commercially available additives.....

Also about your worry for second hand cars run with acetone I must say that I m thinking so opposite....I have seen such enormous benefits......infact its boon to new buyers as its already decorbonised to some extent....

Enjoy....
