DOES ACETONE in FUEL WORK? Im Intrigued.

Hi Folks!

As well as my trusty 300tdi I have just acquired an old M reg Transit 100 LWB 2.5D, the tranny is losing power on the inclines, Ive got to thrash the nads off it in lower gears than should be needed to get up the hills...possible EGR any troubleshooting Ideas greatly appreciated...anyway whilst looking for an answer in the Transit forum I came across a thread extolling the virtues of acetone mixed in fuel, apparently small amounts equivalent to between 1/2oz & 2oz (1 to 3oz for petrol) to every 10 Gallon can dramatically increase MPG by upto 25%, the fuel burns cleaner and more efficiently making the engine run smoother with no side bad side affects, I searched further on google and found plenty of forums with hundreds of people raving on about how good this extremely cheap and simple additive is.

My Questions:

1) Has anybody used acetone it in a 300TDI or 2.5D Transit (non turbo)

2) What was the best mixture (I understand this is critical)

3) Whats the Diagnosis? Any Good?

The Disco, The Van & Her Motor.......£1.15 a litre......Im towing my bag out for nowt a yard here!!

All ponderings very much appreciated as always

Thanks in Advance

Check what pump is on the van and get some veg oil if its a bosch, the only thing i can think that the acetone probably does is clean the injectors a bit and on a older car it can make a sensible improvement

:rolleyes: do you believe in fairies :rolleyes:

I dont know about 'fairies' but Ive done the ACETONE test and I am totally amazed at the results.

Just 25ml to £35 worth of Diesel in the 300TDI Disco........amazing difference and no exaggeration whatsoever.

Although not tried under stringent test conditions (just as above) I have found that the MPG has soared by the look on the fuel gauge after around 150miles from half a tank Im still not down to a 1/4 tank where normally Id have been well into the last 1/4 tank........the engine performance is very noticeable ie hills I was thrashing up in 3rd gear Im now flying up in 4th or even 5th with plenty in hand.......black plumes under acceleration have all but disappeared........no longer sluggish on cold starts (very much so before) and I have to rely on my oil pressure gauge (fitted as a precaution after intercooler upgrade) to tell me when the oil is warm because the engine doesnt know its cold with the Acetone mix firing the car up as if its already warmed up.

If you already tried it without a positive outcome.......try again but this time LESS IS BEST.......100ml to a Tank Full.

Its magic stuff!

No fairies, just proven science, The Acetone breaks up the surface tension in the Diesel (even better in petrol) and enables the fuel to vaporise fully when injected.........result >> maximum fuel efficiency >>> Cleaner Burning Fuel.

Now why wouldnt BP or SHELL etc etc want you get upto 25% more mileage from your tank........ the mind boggles???

TRY IT! ......YOU'LL LIKE IT!!

the transit problem is related to the fuel boost valve inside the pump itself, fairly common problem from that age onwards. any good diesel specialist should know how/where to sort it out.

Thanks Al, Im going to give the ACETONE a try 1st since my landy is running so good on it, but the pump might be a good idea anyway.

Cheers

So what you are saying is after 150 miles you have not dropped to the 3/4 mark whereas before you would be nearly into the last quarter mark, so before the acetone it did 200 to the tank and now it does 500 to the tank which is what a TDI does anyway!

Just out of interest has the disco ever had its injectors checked and/or replaced as mine did 200(ish) miles per tank and after new injeectors is well over 300 miles per tank and should be alot better when on road tyres. It may just be the acetone has cleared some carp off the injectors or is masking another problem with the engine

Since this got asked on the SLRC forum recently I'll post the answer I got from my mate who works for a company that make oil additives for back-yard hacks like Exxon and Mobil:

As usual if it sounds too good to be true it probably is. What he's saying about it acting as a

surfactant is cobblers - it's a small molecule. A surfactant has to

have a polar head group on a fatty long chain. Perhaps because it will

readily vaporise, there could be some kind of physical effect.

Acetone is highly flammable, so perhaps it's just that - but no better

than adding ethanol or some other light solvent to the mix.

I would also imagine that with prolonged use, it would properly b*gg*r

up your seals.

Acetone will boost octane number, but so will a host of other

solvents:

n-octane -10

n-heptane 0

2-methylheptane 23

n-hexane 25

2-methylhexane 44

1-heptene 60

n-pentane 62

1-pentene 84

n-butane 91

cyclohexane 97

iso-octane 100

benzene 101

E85 Ethanol 105

Methane 107

Ethane 108

Toluene 114

Xylene 117

Hydrogen 130

List of common solvents/chemicals and relative octane numbers (lifted

from Wikipedia).

Problem is if you add solvent to a fuel, you change a whole host of

other fuel properties, lubricity, vapour pressure, distillation etc

which will affect the car's performance in other ways.

Simple answer is you will boost the octane content, but you'll knacker

the engine (unless you use fuel additives, of which the company has a

fine range!!)

I've used acetone in my def 300tdi for the last 50000miles. You need to use the EXACT percentage, otherwise it doesn't do anything (at least not with my car). If the mix is perfect it saves me 10 to 20 percent diesel. I don't notice anything else, doesn't smoke les, doesn't have more power.

But now I use 1 liter of diesel at every 10 km's where without acetone I only get about 8 - 8,5 km's per liter.

I've tried it with my Disco TD5, sometimes the MPG seems to get better, but sometimes not. So the result weren't good enough and I now only use it with my 300tdi.
