adding acetone to diesel

earlier Discos have steel tank, but I mix acetone with some diesel in a 5l steel contained first, then pour in and fill up with diesel. The extremely low concentration of acetone in the final mix is highly unlikely to affect anything. A number of people have been doing this for years in the same car without adverse result...

I might also work as a water repellant Baz ;)

I have read that some vehicles with plastic tanks have had problems hence my querey, if you know people with DIIs that are adding acetone with no bad effects i might give it a go.

I will never live that down will i Graeme, lol !!

Nope , never ever Baz ;)

There was a thread on Overlander about using acetone in Diesel . I'll have another look at the links to see if there is any info there.

Thanks mate don't want to stuff the injectors, at $1100ea not a cheap test.
I'll go into Overlander as well when i get home.

Not sure which links you have looked at Baz.

here's a few

The info I can get from these links , and a couple of others , in the amounts being talked about , shouldn't be an issue to plastic tanks.

Plenty of guys running it in Boats and Race cars , and most run plastic tanks.

Your vehicle though , your choice.

HDPE will tolerate Acetone quite nicely, especially in small amounts

Acetone is sold in plastic bottles!

1/4 tank (115 litres)

What kind of tank/s do you have on a hilux to carry 460L of diesel????

Sorry. I didn't write it too clearly. My tank is a 115 litre Long Ranger and so far I have travelled 320 kms on 1/4 of that. so I guess I have used about 29 litres roughly. It seems better than normal milage. I will know the exact figure when the tank is empty.

Hi floyd,

No problems, just wondering though, how have you found the LR tank? I would love better range for outback trips but have always been wary of replacing the main tank. Unfortunately there doesn't seem to be a 2nd tank option for the hilux.

Keep Smiling ;-)

The long ranger fits really snugly where the old tank was. It is machined and shaped to contout around many of the parts like suspension hangers and chassis. It certainly is strong as it has taken a few hard knocks in the high country. It has performed perfectly for 5 years and never needed a repair. It has almost doubled the 66 litre range of the duel cab which suits me as I live a 100 km round trip from the nearest fuel station. The tank just bolted up into the original area and the fuel pick up and guage sender just bolted straight in.

As far as I know there is no additional tank for the Hilux. I am sure you could get a custom one to fit where the spare tyre is but then you have the problem of putting the tyre somewhere else. Other companies also make aftermarket tanks.

I still have the original tank if you are interested. It did a total of 70 Kms on the car and was used for 3 days only. Ot is completely clean. Going cheap.

I'm sure it does, as does ethanol. However some people say that because methanol and ethanol are hydrophilic (water-attracting/bonding) they retard combustion. I always thought small amounts of water enhanced combustion in petrol motors, so I don't know. All I know is that acetone slightly enhances the cetane (equivalent to octane in petrol) rating of diesel but has a much more significant effect in enhancing atomisation/combustibility of diesel and 'advancing the flame front'. Having said that, I always thought petrol combustion was rapid burning (i.e. flame front) whereas diesel involved detonation under pressure - any experts out there?

In a diesel engine, the fuel ignites spontaneously shortly after injection begins.
During this delay, the fuel is vaporizing and mixing with the air in the combustion
chamber. Combustion causes a rapid heat release and a rapid rise of
combustion chamber pressure. The rapid pressure rise is responsible for the
diesel knock that is very audible for some diesel engines.
Increasing the cetane number of the fuel can decrease the amount of knock
by shortening the ignition delay. Less fuel has been injected by the time combustion
begins and it has had less time to mix with air. As a result, the rapid
pressure rise, along with the resulting sound wave, is smaller.
One design approach to reducing combustion noise is to shape the injection –
setting the rate slow at first and then faster – to reduce the amount of fuel
entering the cylinder during the ignition delay period. Another is to use indirect-
injection
