Their curves show mpg increasing up to just over 3oz / 10gal and by 6oz it's a decrease.
Nice graph - I went the source page and thought it would be worthwhile posting what curves A, B, C, and D are. The posting said:

Shown is the percentage MILEAGE GAIN when a tiny amount of acetone is added to fuel. The curves A B C show the effect on three different cars using different gasolines. Some engines respond better than others to acetone. It is important to use the same gasoline from the same gas station when testing mileage otherwise you have too many variables and get undependable results. The D curve is for diesel fuel. Too much acetone will decrease mileage slightly due to adding too much octane to the fuel. Too much also upsets the mixture ratio because acetone (like alcohol) is a light molecule. Acetone helps the fuel become a vapor more easily inside the chamber and minimizes wasted fuel. All it does is offer total combustion of fuel in any kind of engine. The A curve is with a 1995 Neon. The B curve is with a 1986 GMC. The C curve is with two Caravans, 1990 and 1997.

There is lots of self-fuling prophecy in all of this. When you expect an improvement you often "feel" it and even so things to make the conclusion more likely. I think its worth a look. My wife keeps ALL her gas reciepts and mileage for the last 50,000 miles on our minivan (Honda V6). I think it is worth seeing if 2 oz/10 gallons makes a difference to her.

You'll know for sure that she is unaware that this will happen because if she did, she wouldn't let me try it. B a while before I get results--- I have seen how the mileage measurements vary over time, and need multiple tankfuls to get results that have a significance of +/- 5%. Plus I have to be sure I consistently buy the gas for her car.

90Q with 190K - Still running strong and I intend to keep it that way. Since it's being compared to nail polish, I wonder what Acetone does to the inside of the insides of rubber gas lines and fuel injectors + other components? Can you complete this phrase... "If it ain't broke...."

I'll keep my current gas mileage for peace of mind. I'm just happy that I got my AC fixed yesterday. It's all a matter of perspective.

I just went through my first tank with acetone. I didn't have a measuring cup, but I'm pretty good at estimating, so I splashed 4-5 ounces into the tank with about 15 gals of BP 92. Refilled the tank yesterday with 15.5 gals over 308 miles. Not so wonderful - 20 mpg.

I drive the same route every day back and forth to the lake, about 110 miles roundtrip, so this tank without acetone (well, with an ounce or so remaining, I guess) should give me a good comparison. Overland, I usually get roughly 22 mpg. We'll see.

I put 5.5oz with my last fillup. I think I am getting better mpg but I've only driven 160 miles (all in the city). But I can tell you that my car is running much stronger for sure..... I will post after my next fillup. Currently I'm getting about 14 mpg (city)

I'm still working on my 'city tank' but guessing from the fuel gauge I'm not expecting much (if any) gain when it do fill up.

My friend Fred has a late 90s Ford (power stroke?) diesel pickup. I told him 'bout acetone. Here is part of an email I just received from him:

"...and ran 360 miles on 15 gallons, 80 miles of thatpulling a unloaded 16 ft trailer. This is about a 20% gain in fueleconomy as predicted on the chart. Also noted MUCH LESS black smokewith open throttle as advertized. "

What's acetone do for emissions? I've got to take my 1984 Suburban to get the smog test. It's lived outside of the test area most of it's life. Would this be something I would want in the system during the test, or just something to do before the test?

DR.Q, I think the claim is that it reduces the emissions due to more complete burning. My state inspection is due at the end of July also.

There is a ton of ref to acetone & mpg on the internet, here's one. I would have liked the article a LOT better if he hadn't freaked about the the oil comps & gov conspiracy!http://www.lubedev.com/smartgas/additive.htm

If this is all true, should we not also see/feel power increases as well?

Well...filled up after 278 miles. yeilding 15.4 mpg. 95% city and some highway driving. I have been using gas from Sam's Club (92) octane. This time I only added 4 oz to my tank, so lets see what happens. Still, my car is running strong.

I haven't read this post for a while ... just took a look today....

For all you non-believers ... well stick to your routine. For all those who have experienced the MPG gain and power gain.... thanks for trying..

There is NO doubt that acteone increases MPG in the right amount.... 26.xxx miles per gallon in a V8 engine cant be done on regular fuel alone....

Its true that the placebo effect may have some input in this equation.... but numbers dont lie.

Hasn't made you high? I used it again during my 400 mile trip to Lake Chelan (camping) got 20-22 on avarage (mountain driving doesn't really help fuel economy) Cheers!

I guess you're only talking about Japanese made V8s? Take a look at the current breed of american V8 sports cars. They're all getting high 20s mpg

Not really high 20s MPG, I'd say about the same as Y33.Plus, a lot of american v8(sports cars) that require premium are ran on regular which is

I've heard from many people who own C5's and other GM v8's that they get about 30 mpg on the highway. Of course if we could run 1500 rpm's at 75 mph we would too, maybe. I used to get close to 30 w/ my 92 seville and it was even modded slightly.

I put some in my Suburban today and within ten minutes of driving, my lumpy surging idle turned smooth as butter.

Refilled after running a tank with just the remaining ounce or so of acetone, 14.5 gals, 286 miles = 20 mpg, nearly identical to the tank with acetone. I'll run this tank without, and try again on the next fill.

Obviously one or more of your injectors were partially clogged. THe acetone cleaned it out. Most likely a standard bottle of fuel injector cleaner would have done the same thing.

Actually, its carbed. The last tank had the gas treatment in it to no avail. With this stuff it was like flipping a switch. I hope it helps my 9 mpg.

Ok then, obviously one of the jets was partially clogged.

When was the last time you rebuilt the carb?

Well, at a steady 65 mph on the highway in my M45, I get 26+ mpg on the highway. Without using any acetone.

I would say it greatly depends on the speed and conditions, etc. My response was at steady highway speeds. Do you believe that you are getting averages of 26+ mpg with combined highway/city driving?

Just topped off after 171.5 city driving, all short trips & AC on. I don't see any real change, 14.8 mpg. There are a lot more variables in my city miles.

How's this for results?:

no acetone- 116 miles on 13.5 gallons= 8.59mpg

3 oz/10 gal acetone- 152 miles on 10.1 gallons= 15.05 mpg

Same gas station/same city driving. That's just one tank vs. one tank with me eyeballing the gauge. I did let it sit overnight parked in the same spot to read the gauge. Even with a significant margin of error, there's still some serious gains there.

I also took it for the smog test today. 0.00% CO at low idle and 2500 rpm. HC was 128 ppm at idle and 9 ppm at 2500 rpm with 220 being the max. That's easily the best of the last 5 or 6 cars I've tested and keep in mind this is a 1984 Suburban that's probably never been tested before. I did cap and rotor and plugs as well as a new catback before mpg test. And I replaced the cat prior to the smog test, after the mpg test. I did not take it for a smog test prior.

To whomever started this thread: THANKS!

Stephen

The exceleration was smoother, the car seemed a little peppier, and the gas mileage skyrocketed. Yesterday, I drove around 330 miles from Madison, IN to Ft Wayne and then to Logansport. It ended up being about 15/85 city/highway miles and I got around 26 MPG. I had the A/C on the entire time, and had multiple WOT runs during passes. In the middle of that trip, there was also a time when I was stopped for nearly 30 minutes in a traffic jam!

I again tested it on the way home. I tried it without airconditioning for the majority of the trip. I didn't have nearly as many WOT runs, but still had about 3 to 4. On the way home my gas mileage was 29 MPG!!! It was amazing! I now get better gas mileage with about a 50/50 hwy/city mix than I did in all highway driving. The mixture I used is around 2.5 ounces per 10 gallons of fuel and my Q is a Y33.
