29 MPG in my Q! and how? Acetone

[elwesso]

Just so I'm clear...... If I use acetone in my 92 Q with metal chain guides I will not harm ANYTHING in my fuel line, engine, or exaust....

With such low concentrations you wont hurt anything... 6 oz in 20 gallons...

[BobE]

I'm going to make a trip to Sherman to see mom tomorrow. Think I'll try 6oz when I fill up today or in the morn.

-AND- I saw this in the paper today, a Benz: mmmmm bionic!

I've GOT the car for U.. no really!! 70MPG

I'm trying a new combo 300mL addition 25% toluene and 75% acetone USP grade. I'll fill you guys in on the results if I see anything different. I know this cant be wrose than the sh** you'll find in the crappy NY gas. Why not experiment a little -

300mL on a full tank represents about 0.3% volume/volume addition - shouldn't be too bad.

[jamesmost]

crazy man

[tkd_q45]

Any particular brand?

Also - what precautions are you guys using to avoid spilling on your paint? Wouldn't that stuff would eat right through the finish?

[Jesda]

I shoved a tube on to the bottom of a funnel, then slid the tube into the filler and filled through the funnel. Still running the tank of 89, and fuel economy has not improved. Dont know how much is due to 89.

[elwesso]

At autozone, i bought this funnel for $5 that has a flexible hose..... I bought it because i can easily pour stuff in like 44k and things of that nature....

[Q45tech]

Unfortunately to average out the variables one needs to sample with 25 tankfuls..........to be statistically significant alternating over 20,000 miles.

I still have precise data [or as precise as the odometer is] over the past 15 years...........19.2 mpg.............a single year of 10% improvement is nothing more than a blip in gasoline consumption.

[jamesmost]

tech what style of driving represents your 19.2 mpgI have been consistently getting 15.63 mpg with kinda very aggressive driving.do u think that is comparable?

[zinkie13]

In the past few days I have actually done an experiment trying to get as poor of gas mileage as possible. I was WOT from every single stop and WOT as often as possible on the road. I don't think I have driven this aggresively since I drove my Seville. My gas mileage was still around 20 mpg, but I drive the weaker of the Infiniti breed.

[jamesmost]

my wife gets 22-24 when she drives 95Qjust gassed up was gona ad acetone but the jackass overfilled soo much when i opened my gas cap gas was pouring out had to suck it out w/ a rag

[Q_SHIP]

Your supposed to add then fill anyways. It helps it mix.

[BobE]

I added about 6oz and filled up, 14.8Gal 230 city driving, 15.5 MPG.

Made the 136.7 mi HiWay, topped off 5.86 or 23.3 MPG - last trip was about 20.5 MPG.

So tentatively, I'm smiling! BobE

Why 89? I know the cost is nominally lower, but ... have you not read the many threads on this topic?

did not have a funnel w/me so to mix the tank i threw the car sideways a few times

[CJQ45]

I did the same thing!!!! - Its called g-force mixing

The toluene / acetone mixture didn't seen to have much effect - I'm still getting the same milage as I would with the pure acetone. I'll do the final calculations when I fill up and post the results.

DUDE, i added some to my tank this morning, and as i read this i said to myself...SELF...you didn't make sure there was no spillage on the paint....OHHHH SHYTE....that was 2hrs ago...now i'm calln myself every bad name i can think of... fell twice trying to make it to the parking lot. Good 2 go tho'.

4oz Acet, 1/2 chevron tank 93, 1/2 vpower tank.

Bored and curious mostly. I put in a half tank of 87 yesterday just to see what happens. Its slower.

[BobE]

Jesda, I enjoyed strongbad-techno!

I found the same thing, with 87 pwr is less! Glad U 'owned up' to trying it so I'll admit that I've been using it for a while. I didn't see a noticeable decrease in mpg just less pwr. My 23.3 highway was 6 oz acetone in 87. Same conditions as the 20.5 mpg pre acetone trip, 'cept maybe a little hotter yesterday.

[nchopp]

Heh, yeah, the first tank I put in the Q was 89, out of necessity (station was out of everything else, and was bone dry). Slower about sums it up.

[texasoil]

Acetone is an 'oxygenate' and at the concentrations discussed on this thread will not measurably improve or worsen fuel economy in an otherwise clean properly functioning Q45. I personally logged over 35K miles in '03' doing 700 miles RT 1-2 times per week on IH-10 and 2 lane alternate. Cruise speed on IH10 was 79 MPH average (speedometer and odometer calibrated with milemarkers 10 intervals of 10 miles and over 100 miles and SEIKO tachymeter). BEST MPG on IH portion--no stops, was 22.3. WORST was 20.2. BEST was 50 degree day no wind. Worst 100 F, cross winds. no discernable difference between 89 and 93 ON. on freeway. However, if on 2-lane road, with several high power bursts for passing, 89 ON gave less MPG and SIGNIFICANTLY lower power in high temp conditions. Difference between fuel brands significant. SHell and Chevron best. NO-name from WalMart worst. MPG difference cost justified Chevron over WalMart. I DO NOT believe acetone will improve MPG. 35 years of professional expereince in fuels formulation and testing argues strongly against such claims unless the data is supported with calibrated testing. Fuel pump dispensing accurracy, fill level precision, weather, driving consistency and traffic effects all conspire to make 'on-the road' measurement very erratic and imprecise.

( I TAUGHT skilled operators to become certified ASTM Test Engine operators so I DO know something about fuels and their testing)

There is no 'majic potion' to be had.

The loss of power is due to the knock sensor having to retard the timing so there is no detonation. That is why the Q calls for premium unleaded gasoline only.

[jamesmost]

6-8oz. into tank of 93 shell no performance gain will inform on MPG later this week

[FarFetched]

I've just calculated my avrg MPG during my trip to B.C (average speed 70-80 Mph). I had a few WOT and about 5-7 mile "race" (high speed) I would say 80-20% hwy/city(town) driving. I got 23 and some change MPG. Bg44k was used in first tank no difference from the second one. Used acetone trick second tank (~4-5oz ), didn't do much. I guess Q45tech is right about F.I system condition. I didn't use Canadian gasoline(expensive over $3 gal)) so I don't know the difference.

Cheers!

[CJQ45]

Just filled up today - I did the calculation - 26.23 MPG on mixed driving (70/30 - highway/city). The toluene seems to have bought the milage down slightly??? Although I cannot say that for certain since my driving varies depending on the traffic.

[BobE]

"...will not measurably improve or worsen fuel economy in an otherwise clean properly functioning Q45."

I was already thinking that maybe acetone just cleans the injectors. Which I think means the next tank would also get the improved mpg - with or without acetone.

This got me to remembering the good results I'd get with chemtool yrs ago. Here's what I just read at their site.================Q. Is there really a difference between Berryman's fuel additives and all the others I see at the auto parts store?A. Yes. We formulate our products with the best fuel detergents on the market. These detergents are proven to address specific cleaning needs. Specific needs may be in cleaning fuel injectors, which require efficiency at high temperatures in comparison to carburetor cleaning which is not subjected to high temperatures.In addition to the detergent package selected we use "old fashioned" technology in selection of our carrier solvents. We seldom select anything but strong hydrocarbon solvents like acetone, methyl ethyl keytone, and xylene. These types of solvents help rid the fuel tank and lines of harmful deposits, which contribute to fuel flow deficiency and fuel injector plugging. You will rarely find competitive products with solvent cleaners.

tech what style of driving represents your 19.2 mpgI have been consistently getting 15.63 mpg with kinda very aggressive driving.do u think that is comparable?

first tank w/6-8os. acetone first time in years that i got over 15.63 - todays calculation revaeled a 16.5 mpg

If it doesn't work then why did I get 30MPG on my 280 mile trip then on the way home I got 32.57.....this is in our 04 Honda CR-V....I HAVE NEVER EVER GOT OVER 25 MPG ON A HIGHWAY TRIP BEFORE THE ACETONE........That was 540 miles in one day....the gas gauge looked stuck.....California gas must suck.

[zinkie13]

I think some of you guys aren't getting as good of results as other because you are putting toooo much. I would do some testing w/ lower ratios. I use about 2-2.5 ounces per 10 gallon and am seeing amazing results. Some of your are using 3-4 ounces per 10 gallons...or more...and that can actually harm your gas mileage.
