Anyone seen this gas mileage idea???????

those examples don't apply in this case... there is no patent on Acetone and it'd be impossible to stop people from adding it. It'd be like if adding a cup of water to your gas tank gave you 200 mpg... once word got out, it'd be impossible for "big oil" to stop it. The oil industry is big, but it isn't the all powerful force some left wing kooks describe it as.

My respons was in the text of the previous comments made in this thread. "if it worked the oil companies would be using it"
I was simply backing up my thesis on the oil companies dont want you to get better MPG by showing you that they have been buying up all the patents to all the technological advancement in fuel efficency.


and the reason it has not taken off is probally due to
A. it doesn't work in all or some cases(maybe it depends on the fuel system used)
B. becuase people are using the oil companies quote from above
c. The fact that acetone can eat through rubber.

A grad student here at my college wrote a paper on that and presented it to my class. He said that there has been 100s of inventions/inprovements over the past couple decades to internally combusted engines making them super fuel effiecent. he gave alot of examples, ceramic motors, etc....cars getting 50-100mpg. Why have we not seen these? Because the oil companies bought the patents to them, thus stopping the technology.
If there could be an improvement to the engine that cut the gas useage to 1/2 or even a 1/6 of what it is now you know what that would do to them?
They want you to use a much possible. He also talked about the ties from the oil companies to the car manufactures and there huge influence on the way cars are made.

That comment is not very accurate at all. I'm sure there are people out there who have come out with engines that are capable of getting 100 mpg, but the reason they are not on the road is NOT because of oil companies buying them out and hiding the technology. The biggest hindrance to most of these technologies is the cost to develop and build them.........not to mention possible long-term durability issues and replacement parts. A 100 mpg car is great, but not many people are going to buy a econo-box with a $50,000 sticker price (hypothetical, of course, but you get the point).

I can just tell from the way people (still) drive that their economy is due to driving habits more than anything else.

With gas at $2.50+/gallon here, I still see people driving their vehicles at 10+ MPH over the posted limit on every road/hwy I travel, and doing every other un-economical thing you can think of.

Those two sentences are the most accurate about fuel economy in this thread. I've owned a semi since 1993, the fuel bill comes out of my take home pay. The accountant has made me an expert in cost per mile figures. You want to discuss fuel costs, try this, my fuel bill for 2002 was $28,795.83 and last year it was $46,605.91 Yes I took a $17,810.08. pay cut last year. What used to cost me $.236 per mile in fuel now costs me $.389 per mile.

Peoples driving habits haven't changed yet, they will but it will take $3.00/ gal or higher fuel costs before they change. I live in Minneapolis MN and the majority of the metro area has a 65-70 mph speed limit. Its only 55 in the very downtown areas. How fast is fast enough in a heavily populated area? The Wisconsin state troopers set the radar guns at 73 for the 65 zones. A trooper told me that they set them so high to avoid writing to many speeding tickets. Basically they have so many troopers and need them to do other things then write only speeding tickets I can set my cruise at 65 in Wisconsin and all most everything else passes me. For a semi every 1 mile per hour over 55 costs an extra .1 mile per gal in fuel. So if you get 6.5 MPG at 55 you will probably get 5.5-5.8 at 65. I know there are exceptions to this but this is for a general idea on fuel economy.

IMO the 2 biggest factors on economy are drving habits and maintaince especially tire pressure.

Sorry for the rant

Here is a reply I got from Berryman's.

Acetone is an effective additive to fuel that provides emission reduction, fuel economy improvement and helps reduce internal engine fuel deposits. It increases the vaporization effect of gasoline and acts as an oxygenate to allow the fuel to burn hotter.

Although the extent of it's effectiveness can questioned and may vary from case to case, acetone's use as an additive is definitely plausible.

For those skeptics who disagree with the above quote, please show us YOUR credentials.
 
You guys who are saying you are getting less, or saying it doesn't work...

I'm running this stuff in a BRAND NEW engine... yeah, I know... why would I want to ruin a brand new engine with a test that isn't proven... well... getting 15mpg+ without changing my driving habits has me as a believer. I'll keep updating what I'm getting.

Current tank update, I've used 1/4 tank of gas since Sunday, and I drive 45 miles round trip to work and back with some city driving during lunch. I also filled my tank in Milwaukee, an hour from where I live, so that's another 59 miles to add on. So far, I've gone 140 miles on about a quarter tank of gas... I have a 25 gallon tank, so that about 6 gallons. 140/6 = 23.3333333, which is freekin impossible for a blazer. I'll post real numbers when I get them... lol
 
First update from me using acetone...

On the previuous tank of gas (wihtout acetone) I noted that my fuel gauge in my DD is very accurate, I was at approx 150 miles on the trip ODO at half a tank, and fininshed the tank at 301 miles. On my current tank (with acetone added) I have 165 miles on the trip ODO and am a hair over half a tank on the fuel gauge. I am not willing to say there is an actual improvement until I see where I am at when I get my next tank of gas, but it would seem that there has been some.

I also noted that my engine is running a little smoother now, so thats not a bad thing either. If nothing else, this little experiment has taken my mind off of the high fuel prices and made filling up a little more interesting :grin:

I'll post some official numbers when I fill up again to see if there is any big difference overall. I have to say that if I only net about 20 miles more per tank I doubt I will continue using the acetone. The time/effort to buy and add the acetone to save 1 gallon of gas is not worth it to me...but we'lll see what the numbers say.

i should email the guys on myth busters. Maybe they can test this thing on the track. Like the a/c on and a/c off experiement. get some "real" results.


anyhow.
this has been known long ago in the fiero community because smokey had it in a fiero.
http://www.schou.dk/hvce/?mode=2

I know i had this article someplace and need to scan it.

the concept is to heat up the fuel mixture to cause it to vaporize and increase pressure. Causing the vehicle to increase in fuel mileage.
 
i tried it

I tried it in my nissan pickup that I put alot of miles on. I didn't check the mileage 1st because i thought i was getting about 20 and I really wanted to test it.Well I put way to much in my 1st 14 gals just eyeballing it.Averaged 18 gallons so i was getting less than that or the same before.Just filled up again today and I am averaging just shy of 20 MPG. Now I drive mostly highway and 78-83 MPH. so far I'm pretty confident that it works.
 
Just an idea... does anyone have any friends with a dyno? A lot of dynos have really accurate fuel flow meters. This would be the most accurate way of testing (ambience and running conditions are standardized - less variables.) Not to mention, see if there is any actual change in power.

All in the name of science....
 
Who has run this stuff for a long time? Any problems or complaints?

I think its still up in the air... rene said he saw no mpg improvement and so did a few others but there are just as many saying they say better mpg.

I agree with dyeager35 and smalltruckbigcid... its driving habits. thats the only way to explain the different results.

IMO there is no way oil companies could stop that kind of stuff from getting out... people would find ways to get around the patent and make knock offs that have the same effect on mpg not to mention that if they kept the patent instead of selling it to oil companies they would make 100x more if they signed a deal with a manufacture to get say 10% of earnings on every peice sold.

what were all these things called and what did they do?
 
The only thing I can say for sure about acetone is that my engine runs better now. It had to warm up quite a bit to run smooth in the mornings, since adding the acetone it has smoothed A LOT. There is a real difference in how it runs, that I am 100% certain on. It looks like I will get more mpg's as well at this point, but probably another week til I fill up again.
 
I just finished my first tank with acetone. I have an 86 one ton 6.2 diesel with a 465 manual, 205 t-case 4.10s and 35s. I used 4 oz. in a 20 gallon tank. I usually average right around 14mpg. The tank with acetone got me 14.19mpg. I will be trying a few more tanks to see if the average looks any better but right now it doesn't look like any appreciable change. The truck didn't seem to run any different. Although, It ran pretty good before.
 
well i'll try acetone in gas soon enough,we clean fiberglass, fiberglass resin with acetone all the time...i cant wait to see if it's gonna work :D
 
i think there is more then one factor effecting the experiment.

we cant just go out and test ONLY disel, carb, TBI, and EFI and say it dosent work or DEFINATELY works.
 
They have got this same thread going over at the pirate4x4 board. After much skepticism, the general consensus is that it works. All I can say is give it a shot. I am overseas right now, but I am gonna try it when I get back. Let's see some more numbers posted.
 
Ok! So heres my results with acetone so far
Filled up my K5 2 weeks ago. added 6 oz of acetone in a 30 gal tank.
Didn't drive my k5 as much as i thought I would. I only put on 370 miles in two weeks.
Just filled up today. Used 21 gals of gas. Went to the same gas station and used the same pump. filled up the same way I always do. That = about 17.5 MPG. Mostly used my blazer driving back and forth to work 44 mile commute. 40 miles highway and 4 miles city. rest of the driving was city driving getting grocerys, car parts, visiting freinds ect.
I usually get around 15 MPG average city and highway.
My milage definatly went up. After the first 1/4 tank the gas guage didn't go down as fast.
I know that a little over 1/2 a tank is not a good test of gas milage so I'll see how this tank goes with the same mixture of 6 oz acetone per 30 gal of gas.
I'll post next time I fill up and average it all together.

It works because acetone is used as a fuel injection/carb cleaning additive. Or because it somehow changes the surface tension of gasoline?

I already know that my 3m fuel injection cleaning system works and improves engine performance. But that is due to the fact it cleans everything in the fuel system and inside the cylinders. Of course, it improves fuel economy because it removes carbon and cleans the internals of the injectors.


So is the point now to this thread is that people never put a fuel injection/carb cleaning additive in their gas tank and now see an improvement in mileage?

Acetone doesn't change the surface tension of gas... it is used as a FI system cleaner though.

yeah, but the question is how often do you need to use it to get the marginally better mpg? Once its cleaned of deposits and gunk, its clean. I don't know how long it takes them to build back up, but its wasted additive during that timeframe.
