Miracle for fuel economy?

Jeph:
It's supposed to lessen gazoline's surface tension allowing a better atomisation, hence a better (more uniform) A/F mix. This gives a better (more complete) combustion. In theory.... Right now I'm doing the practice to see for myself

Kooldino:
After a 1/4 tank my exhaust tip would show some black and after 1/2 tank it would be noticeably black. 1 full tank and I could hardly see the stainless steel (just the top part). I have the round tip Mazdaspeed exhaust (warranty replacement)

I understand the theory behind it, but I bet my mom uses that much when she cleans off her nail polish, so i guess its hard to see that much mix with 10 gallons of fuel.
When did you add it to your tank? before or after you filled it up?

If I remember some of my chemistry (I used to study it... long time ago!), sometimes a small quantity can have great effect. It's not Acetone itself that makes a better mileage, but it's effects on the gasoline. The quantity is similar to some of the octane-booster shots (ex. Pennzoil)

The first time I added the Acetone in the tank that already had gas in it. The second time I put 25L of gas after I put it in. I'm gonna check this again as it seems it's better to put gas before the Acetone (which is more convenient BTW)

your braver than i am, i feel uneasy running 91 octane in mine.

Any more results for this?

I did it and will know in about a week if there is any improvement or not.

I'm driving up to Denver next month. I have made the drive before and know how far i can go to each town, I will try it when I go.

This is truly historical.

i will try to do this as well. i have recorded my gas mileage for ALL my fill-ups from the first one. i average around 310 miles per tank. i'll go grab a thing of acetone tommorow from somewhere.

Well, after a week of trying this, all I can say is that it WORKS!!
Soon I will post my results (I'll have to work the math for US gallons) but for now I can say that I've seen 15 - 20% improvement (more on the 20% side), depending on driving style. Besides that, the engine runs very smoothly and there is less soot on the exhaust tip.

 

[FlyinMSP]

Also, yesterday I checked my plugs and they are GREAT! Actually, even better than usual: the black soot which is on the outside ring seems to come off (i.e. get burned) so Acetome might also clean the engine pretty well....

The NGK Iridiums I've been using for a year now have always shown a strong tan-colored tip, now they are light-tan which is better. I've now swiched to my Bosch +2 to see if that combo is better (it gives me more torque for now) for fuel economy.

1sty, any word from any of your brainiac buddies on Acetone doing any harm on the enginne/catalytic converter?

I'm wondering if you go back to straight gas if you will still get the same mileage. To basically test if it either works as a sort of cleanser that only needs to be run every so often, or if it must be part of the combustion process to give improvements. If that makes sense.

add O2 sensor to that question

 

[jrodhotrod]

Okay, I'll give this a try.

I'll give it a go in a 1995 Dodge Intrepid first and see what happens.

Everyone keep us posted.

I wonder if the added power/efficiency is from added octane rating => less signal from the stock knock sensor => less ECU retard on timing. Anyone know how common it is for the stock knock sensor to cause timing retard?

guys'(blitzd) father in law is a genius. he says it's good and he uses it.

Actually, the added efficiency come from the acetone causing the gasoline to vaporize much better.

Good question.

I don't think it's very common on our cars.
