Title: Acetone additive
Post by: Tony on April 28, 2013, 10:09:54 PM
Thought I'd try some in the Delica, a tiny splash in the bio.  Trying now to work out whether it seems smoother because I'm psychologically wanting it to be that way (or because I just replaced an upper arm ball joint and it no longer makes nasty scraping noises for every bump)?

I think Dick tried some in his Delica with no obvious effect which really is what I'm expecting :)

Isn't the standard line that it works for some people but not others?  And some argument about spray pattern and aided atomisation?  I can't see how so little acetone would have any effect.

When I do any changes in process I don't tell SWMBO, if she notices anything then it must have had an effect.

The last time she reported an improvement was when I swapped back to water washing.

Get the missus to add some to your tank without telling you and then see if you notice anything?

Don't think my misses would notice if I changed the car, so I wouldn't hold out any hope for a change of process!

My misses never notices when I change me pants, I don't bother any more 'til they get too crusty and uncomfortable to sit in.

That was "sit in" wasn't it?

Yeh, the skid marks end up like 36 grit sandpaper after 5 - 6 months of use, don't 'alf make y'bum sore.

Jhanananda tried using acetone as a general thinner like we would petrol he never mentioned performance or economy that I can remember though. Think it started to eat the rubber at over 10%

However that's the only impact I know of for sure, I've tried with and without acetone on the same run to and from work and had little to no impact on performance or mpg.

The only definite improvement with the Transit I've found so far has been Veggie boost and any other cetane boosters I've thrown at it.

Turn them inside out and you'll get twice the mileage!

Yes I tried and it made no appreciable difference, mind you with the fuel consumption it would have to be a big change to be noticeable. Must try some in the skoda.
Still experimenting with adding some when brewing. It does seem to make a bifference ere but the HMP? Have been an issue. Droning another batch today with it after some without.

I'm experimenting with various volumes of Acetone in B100 after reading the paper put up on the VOD.

I'm trying 0.75ml/ltr ATM and will move to 0.8ml and so on upto 1.5ml/ltr to see if I do get an improvement in MPG as predicted by the info published.

Well I've been trying it for a while and can't tell any difference TBH.

 I ran out of Acetone some time back so my fuel and car has been off it for some months... My car had been feeling rather sluggish and IMHO getting slowly worse ! last week I found half a litre of Acetone hidden away on the bench and added about 50ml to what was a full tank and within 50 miles the old girl was improving and is now back to her spritely self at half a tank.

I'm upto 0.8ml/ltr and have notice a slight increase in mpg, I'm getting 52+ mpg on motorway runs in me Picasso.

I've not been adding as much as that (0.3ml/l). I'll try a stronger dose.

Adding around 0.75ml/lt is a starting point and may have a positive effect BUT there's a point where Acetone  will reduce MPG.

I started at 0.75ml, I'm keeping an eye on mpg as I increase the dose to a point where nothing more happens.

I do a regular road trip up to my boat and back where the MPG test take place, same route same distance every time.

I wonder, like adding petrol to WVO, whether the small molecules of the acetone help with biodiesel viscosity as well as atomisation?  Would it work just as well with IPA or is there something special about acetone?

I'm running 0.8ml/l now, if anything it feels like it has lost some power.

I've been using about 1.5ml/l for sometime now, and it does give a noticeable improvement to both mpg and engine responsiveness.
It's more noticeable on the 206, without acetone it feels quite sluggish, with acetone it's like a new car.

I wonder why mine feels sluggish on less then? Maybe Acetone taking the paint off something and it ending up in the filter?

Probably because 0.3ml/l is no where near enough to have the required effect. A bit like drinking American beer when you want to get drunk.

It was fine at 0.3ml/l, but feels sluggish at 0.8ml/l

With you on American "beer" though, if you can call it that.

But you said at .3ml you couldn't see any difference, and you were going to up it?

I wouldn't be surprised if the ideal dose is dependent on the feedstock used

I was being generous with calling it 'beer'.
