If my guess is correct, U'd get the same mpg with out it now. Have U tried a tank without?

Actually I tried not adding any to my last tank just so I could make sure that the mixture was the way I wanted it. My mileage was still improved from my original mileage before I started, however it was nothing compared to what I have been getting. I normally get around 20 mpg w/ mixed driving. The last tank without acetone got me around 22.5. With acetone I get about 27. You guys can believe it or not. Just search on google for testimonials about it. A 35 percent increase in mileage does not seem to be uncommon. I read that some guy in a 95 dodge neon was getting between 53 and all the way up to 73 mpg.

I wanted to say Thx for posting this & thanks for sticking around to beat the drum! ;-)

As I said earlier my one data point says it well over 10 closer to 15% improvement.

I just did some reading (per Ur suggestion) and I like this article a lot!

http://www.lubedev.com/smartgas/additive.htm

Their curves show mpg increasing up to just over 3oz / 10gal and by 6oz it's a decrease.

(For diesel it peaks at just over 2oz but I guess most here don't care 'bout dat!)

How do fuel economy monitors work? How would a change in the formulation alter the reading on the display? I always assumed they were based only on speed and RPM.

Yep, I'm like U the only ones I knew 'bout monitor 2 things actual amount of fuel use over a measured distance. That requires a flow meter and an odometer. The 'puter can show instantaneous mpg or some longer average, like trip mpg.

You've won me!The vehicle is a '95 Ford Fairlane Giha 6 cyl auto 188000 kilometers. My Trip 'puter is in L/100 kilometers. The average has been 12.9 L/100 k's over the last 5 or so tanks. I put 125 mls of acertone in and topped up (60 + Litres). Over the next 100 kilometers I watched the trip computer drop rapidly to 8.8 L/100 k's. This was using a very light foot. On the 500 kilometer round trip the reading was 9.3 L/100k's. I'll be very interrested to get an average over 5 tanks with acertone and then without.

I used Shell 95 Octane @ $1 Litre

Thanks for the Tip!Aussie

They just know the injector open time, number of cylinders, and then calculate it on so many cycles.....

I'm just wondernig how are you guys calculating your gas mileage?

How can you be sure that you're consistantly draining the tank to a certain amount before fill up?

How are you eliminating outside variables, ie human driving?

Short answer, you're NOT. There are too many variables that you're not measuring accurately.

The ECU does not know what the mixture of the fuel is. It does not adjust flow rate based on the mixture.

Are you measuring the flow rate over time to calculate the lbs/gallons per hour? Most likely not.

.Sounds like snake oil too me.

Yea there have been fanboys of various fuel additives on here before spouting off. Just as q45tech has said time and time before, it is theoretically impossible for the Q to get 27 mpg under regular driving.

How about someone else tries it, so we can clear up this waste of forum space

NOt impossible: YOu just need to shut off 4 cylinders

If you truely want to increase your mileage reduce the weight of the Q. Start off by driving around with 1/4 tank of gas. That's like 100+lbs off right there. Change out the seats 100Lbs.

Remove anything that's not essential.

Duane who hasn't been on this forum for 2 years or so, totally gutted his Q. I bet that thing was a beast and fun to drive on the track, the only place it could be driven

Ironic that everyone's driving habbits who have tried using acetone all change so drastically that their mileage increases 30 percent. I know some of you guys don't believe and never will. Just like some of you guys all believe that OEM is the best, but some things just work and no one has an explanation better than it just works to explain it. I know for a fact I am getting better mileage by a longshot.

I for one am all for saving money(gas), but like to know exactly how/why something works, if it does indeed work.

I believe that unless you are somehow measuring the flow rate that you calculations are off.

Ok you can believe what you want. But I calculated everything the same before and after I started using acetone. Divide the miles traveled by the number of gallons used since the last fill up. I never overfill. I always go to the same gas station and always take the hose after after it clicks off the first time. Maybe the acetone actually broke my odometer in a way that would make it look like I'm getting more miles.

Hmm, now your measurement actually sounds reasonable becasue you're filling it up to about the same level every time.

But I'm just not seeing where you are getting a ~30%+ increase in mileage from. Auto Manufactures would KILL for that kind of increase.

I'd say the 21-23 mpg increase was merely cleaning out the system. Improvements after that I believe are due to the effect of the acetone. I may be one of the few on this forum, but if you google the subject there are many people w/ many different makes of cars seeing huge increases in gas mileage.

As far as auto and gas companies I believe the reason this is not promoted more is because it seems like each vehicle has a different sweet spot. Most seem to be around 2-3 ounces per 10 gallons. However, some vehicles may see a decrease in MPG when they hit the upper limit of that range. It also hasn't been 'proven' to be safe on all vehicles. A company wouldn't want to start promoting something and then get into a legal battle when the coating on some internal part begins to corrode.

Quote »But I'm just not seeing where you are getting a ~30%+ increase in mileage from. Auto Manufactures would KILL for that kind of increase.[/quote] One hand washes another hand. Even though car makers "all about" MPG cuts as G.BUSH jr. proposed to see in 2007 , hovever we all know that G.BUSH is "all about" cutting production of oil and related hydrocarbons. Most car makers save BIG $$$ even by cutting MPG 1-2%. My ex supervisor is working on "steam assist" in gas and diesel engines. Earlier this year their team wrapped up R&D and were getting to patent it. I won't go inot details, but system is similar to a steam engine which is add-on system wich displaces some air/fuel mixture in combustion chamber thus reducing fuel consumption. As far as I know very few (if none) side effects. I can see how this system can save you some gas!Acetone might save you a bit of gas but not 20-35%. V8 are notorious for consuming more gas even idling.

I think that this is being blown out of proportion...

First of all, a GALLON of acetone costs like $10. big deal, if you dont order a coke with your happy meal during the week youll save 10 there.. So its not like its a big investment

Second of all, its hard to refute what people are reporting unless one or all of 3 things are happening.. 1. They are lying, 2. They are miscalculating, 3. something broke

If you are getting good results, great!! Keep using it!! If your not, no reason to flame it, it wasnt a big investment...

I know my gas mileage is accurate because I always go to the same station and i always use the same HOSE every time (the easiest one for me to pull up on the passenger side)

Thx Wes, Gr8 post.

I know some other people that say U just can NOT check Ur gas mileage. One very accurate method is to keep a running total of miles driven and gallons added in a log book. The longer U run this total the more accurate Ur answer.

However U can get mpg within a few % even on a single tank.

You cannot forget other things that affect MPG such as traffic, long red lights, warm ups on a frosty morning, going faster than 60-65 om hiway and so many other things that could throw "good" Mpg out of the window. If my Old Lady is getting 19-22 Mpg in city/hwy combined driving I am good, I am good.

Are you who are trying this adding the acetone before, during or after fillup? I realize it's probably a long shot but gas prices being what they are I'm willing to try it. I have a consistent commute every M-F (plus having driven Qs since 96) and I'll know pretty easily weather or not it's working.

I put it in before fill up, don't know that it matters. Be careful not to go over 3oz / 10gal as the curve above shows that mpg falls off steeply above 3oz.

Just put 6oz in RIGHT before you put the nozzle in... If its at the bottom of the tank, the gas coming in should mix it up decently.. Then you can go on a sprited drive in the twisties to mix it further

Look the bottom line there is a whopping 1 person reporting that they are getting what would generally be considered prior to this post a completely ridiculous MPG number.

There is a very simple way of putting this issue to rest, and that is others on this forum trying it. If it's a miracle product like you claim, then everyone should be reporting the same results.

Well you must also understand I drive an inferior vehicle, so that could be the reason. I believe more ppl than just myself on this forum have experienced MPG measurements of around 25.
