29 MPG in my Q! and how? Acetone

[elwesso]

I added approx 8 oz (little under 4 per 10 gallons), and so far theres not much difference. Just eyeballing it, but im stiting at 120 miles or so at 3/4 tank...

[Q45tech]

Worries me that some members continue with this post as it was started as a joke..................impossible to affect mpg as long as one operates in "closed loop" mode.........unless you can find a way to remove any oxygen molecules contained in fuel mixture.

The sweet spot [% graphs] was there as an excuse to blame when it didn't work, you must have added too much, too little. It's your fault it didn't work...DUH!

Turmeric/curcumin sales have increased 30x since the stories about "curry" and Indians [India] have much low cancer rates than US.........no meat [low protein] is the answer not so much the curry. I even bought a few pounds of the pure and $20 worth of tablets.

It's amazing that we tolerate oxygenated [ethanol] gasoline..........pseudo science to Subsidize farmers at the expense of our population. Don't most religions teach that alcohol is bad.......oh that just to drink it.....[possibly there is a connection - bad for humans, bad for engines].

you people are damn brave to put things other than gas in your gas tank

Well, some things are useful though!

ISOHEET (not HEET) to remove water condensates and BG44K to clean injectors, comes to mind.

curcumin as anti-cancer agent has recently had some very positive results reported by very prestigeous cancer research hospitlas. Too early yet to say for certain, but several phase 1 studies have shown VERY positive cancer reduction results. Phase 2 studies in progress, and phase 3 expected to start this summer.

I just dont like being closed minded... Its not gonna hurt anything, I had some free acetone that i got, so why not try it?? It didnt do anything for me it looks like......

[PoorManQ45]

Yep, why not try it?

If anything it'll clean the fuel system out better then any of those "watered down" fuel injector cleaners.

That may be where people are experiencing an increase in mileage. The O2 sensors may be reading lean causing the pulse width to be increased

No harm in trying as long as whatever you add is not likely to damage the engine!

Please just keep us posted on what you see!

I checked my city mpg again at about 15.75 then I added acetone and filled up. Just got back from a 140mi hiway trip & it's 23.1

I plan to chk it with none on my next hiway drv in a few weeks.

I was REALLY wanting to see upper 20s today...

Q45 tech - if this thread is a joke - or hoax - shouldn't the moderators do something about it? I hate to think that it is OK for someone to do this.

[zinkie13]

Please read. However much you guys hate the truth, results don't lie. This may be a repost but i didn't wanna read the entire post again looking for it. http://www.lubedev.com/smartgas/additive.htm

[elwesso]

I certainly find it hard to believe that this many people are lying or crazy......

It didnt work for me, i wont use it... Im not gonna make a fuss about it if others want to use it...... It probably does other things that even the people here have not thought it *could* do.....

If it works for you, great, keep using it... if it doesnt, who cares? you didnt waste a lot of money trying......

[zinkie13]

Basically thats it...Wes explained it in a nutshell...if it works for you...sweet...if not...who cares...you spent a maximum of 10 dollars and cleaned your fuel lines out!

I tried it because I had free acetone... im much too cheap!!

[tkd_q45]

I'm presently trying it - but will have to wait to next tank as when I disconnected my battery - lost my odo reading. Seems to be a bit better, but not much (do the same commute w/same conditions every day M-F and have a pretty good idea gas gauge wise how much it takes to get me back and forth.

Various quotes from Dennis ... collected from a few threads ...

At least these experiments do no harm..........m/p-xylene, toluene, acetone, isopropyl alcohol [dry gas].............avoid methanol [rubber fuel hose damage for sure].

That is good to know!

Didn't work for me.............no changes in 5 tank fulls over 2 weeks [1500 miles of mixed driving] [each day 60 miles at 70 mph] and [ 60 miles in slow traffic]............ ~~100 gallons of gas with a liter of Acetone USP.......0.25%.

Dennis tried it the way the lubedev article suggested ... with five tankfuls of gasoline. And did not see a gain!

I also think that those of us who are reporting results (or lack thereof) on a single drive (without using a tankful of gas) or even a full tankful are not being realistic, since the conditions over one tankful, or a single drive, are not going to be consistent enough to demonstrate a perceptible improvement.

I am tempted to repeat my M45 mpg drive test, since I have the equivalent of a ScanGuage on board to measure the instantaneous mileage (or certainly averaged at a steady speed over some miles.) Here is what I did about a year ago: zerothread?id=59766.

It might be worth repeating this, with and without acetone in the tank!

There is only one way to measure true MPG is to get 2-3 tanks from full-to-empty. Method of eyeballing fuel gauge is simply inaccurate. Get a gauge that shows real time MPG. Acetone didn't work in my case, so am not an advocate of it. It is true sometimes hard to withhold yourself from pedal-to-the-metal that is why MPG cannot be constant. I thing this tread shoud end on a cheerful note

[BobE]

Wow, thx Z! All of my posted hiway mpg has been between 75 to 80 mph. I'm not sure I'd feel save at 60mph on HW 75 North to Sherman - I might risk 70mph...

================

• Indicated 60 mph: 29.1 mpg
• Indicated 65 mph: 27.0 mpg
• Indicated 70 mph: 25.6 mpg
• Indicated 75 mph: 23.2 mpg
• Indicated 80 mph: 23.2 mpg

For me, it was late at night, so there was hardly any traffic, so going 60mph was not too bad. I had to keep eyes peeled for highway patrol at the higher speeds, though!

Also, those were all without acetone (at that time, I had no clue about this possibility!). So, if I find time someday (hah!), I will repeat it and then immediately (to keep all other variables as similar as possible) try a direct comparison test with acetone to see if it makes any difference.

ROFL! Yes, indeed!

The only way I was able to do my mpg tests was by using the cruise-control! That is one nice thing about the Q and M - on level ground, they hold their speed perfectly.

[tkd_q45]

I realize that watching the fuel gauge is not the most accurate way to go but I've been driving (some form of) a Q since 1996. I am really observant of how many miles I can drive in relationship to the needle on the fuel gauge. I also have a consisten commute (mileage, traffic conditions) that I drive M-F, I fuel at the same Chevron station every time. That said, I do agree that it's best to test over several tankfuls.

Do you use CC on hiway ? I do it only if I am completely retarded that day CC is for old geezers Cheers!

Occasionally. I don't normally use it much - just turn it on when I want to not concentrate too much and am going only a bit above the speed limit. Otherwise, it stays off!

For the mpg measurements, though, I wanted to hold the speed very constant - without my influencing the outcome. Hence, cruise control was necessary.

Hey, I resemble that remark!

Yeah, if not there already, I am getting there for sure ... oh, well ... happens to the best of us!

i have usede about 5 tanks and the 1st 2 i actually had a small dip in mileage, i was adding too much acetone i think, i cut back to about 4 ounces for a tank, about 18.5 gallons. and saw an increase from about 16 mpg (i drive hard) to about 18 mpg, i stopped the acetone (becuz i forgot the can at home) and the next 2 tanks i got about 19 mpgs, so at least it cleaned the system and improved my mileage performance somewhat. I do think that less is more though, try adding about 2 oz per 10 gallons

[BobE]

Yesterday I filled up after 243 city miles, 15.7mpg. I didn't add acetone this time, made the 142mi hiway trip @ 80. I got 21.1mpg. I may have had a little heavier foot, but not much! So for now I'm still seeing about 10% better hiway milage w/ acetone. My plan is to try 70mph next trip...

I checked my city mpg again at about 15.75 then I added acetone and filled up. Just got back from a 140mi hiway trip & it's 23.1

I plan to chk it with none on my next hiway drv in a few weeks.

[Q45denver]

10% improvement sounds about right. I figure I'm saving about $4 a tank and car runs better.

[zinkie13]

Well I'm glad it wasn't a complete failure for everyone!!

I think here im going to get some small bottles and measure out the correct amount and then leave them in the trunk or something...

My car ran slightly better..
