G'day, Back when e85 started showing up around here we had people filling their non flex fuel cars with it thinking they were really saving some money. It didn't take long for the e85 to cause some damage. I remember selling a lot of injector o-ring kits, injectors, and fuel hose.

I have also noticed that "modern" gas seems to go flat much faster than in the past especially with the winter blends. It seems that you get that varnish stench in a couple of months rather than years. The 10% alcohol also causes trouble in small engines around here, especially snow blowers.

All in all though, I can't see a few ounces of acetone per 10 or more gallons of gas doing much of anything. I may have to try a similar experiment with a controlled mix of acetone and gas and see what it does to o-rings and fuel line.

I did experimentation with Acetone on my '91 C1500, 4.3 TBI, 2wd, and logged the data. I can't find the data I recorded, but there was no significant difference. There's more MPG to be found with engine tuning and other tricks.

 

Time for an update. The things I put in the acetone on Saturday are still there. I pulled everything out and as far as I can tell there are no negative side effects so far. The O-rings did swell up a little bit. When I saw that I looked at the package for them and it specifically said that they are not fuel line O-rings. That explains why they swelled up. Since they did swell without cracking, breaking, or disappearing I will continue with the experiment. I still think this test is valid because none of the other rubber fuel system components are experiencing any kind of negative side effects. At the end of the day I figure that if the parts hold up in 100% acetone for a week then that should equal years at a 3oz to 13gal ratio.

If when I try this out as a road test I get positive results I will do a more in depth experiment to determine negative side effects. For that experiment I will take mason jars and fill them with the gas/acetone mixture and put in fuel system components. That would be monitored for much longer then a week.

 

Did you close the container during the soaking period so the acetone keeps its "strength"?
And regarding the driving test; are you doing the test to see if it improves mpg by cleaning the fuel system and components, or by improving the fuel mixture? If it's the "system cleaning", then maybe you need to wait after the acetone use for 2 further full tanks use before you can check the mpg

 

It was in a sealed container. I'm testing it as a mixture more so then a cleaner. I was thinking about running it for a bit and then checking the mpgs without it to see if there was a difference.

 

I have used it in several vehicles over the years. No bad effects came from using it. Some vehicles I noticed a slight mileage increase. You only use a few ounces in a tank.

 

I've ran a car on moonshine but it ate up everything rubber pretty fast. Didn't do any long term studies but it seemed to drink that stuff faster than gas. Then again maybe it was us drinking it and not putting as much in the tank each time.

 

So I put the first thing of Acetone in the tank. Prior to doing that I averaged out my gas for the past bit and I'm getting between 14-16mpg. I will keep everyone posted on if and how much it increases due to the Acetone.

 

Years ago in eastern Oregon I was up by Anthony lakes west of Baker City and ran very low on gas,I had two gallons of white gas in the camper-guess what I did! It worked! It got us out of the woods in a single tank 78 GMC to a little town called Dale! And the truck had no adverse effects at all! We still laugh about that one!

 

i have tryed about all the MPG tricks out there are and none of them gave any significant gains, any gains that were made was eaten up in additional costs for product or additive.. the only real and very noticable gain is removing the ethonal from the gas, there is a 3-5 MPG increase,
so it seems our wonderfull government stuck it to us once again, increase
fuel cost plus reduce the MPG, way to Mr. President that won a Nobel Peace prize
Oh, and he wants to make our fuel prices equall to that in Europe, just a heads up
