No change in gas mileage after adding the acetone?

The avg MPG before the test was 28.5 with this tune.

The acetone increased mileage slightly.

Further study is needed.

Can someone help me out with a couple of questions?

Ive looked in my manual and am trying to find out what engine, SOHC or OHV, is in a 95 XLT V6. And am I correct is stating that the difference is valve actuation, either directly by the cam or indirectly by cam to pushrod?

Secondly, Im sure everyone has noticed that every tire in creation, at least that Ive seen, states the max pressure in relation to max load. (ie Max load of xxxx lbs at 35psig max) My question, what is the max pressure with no load? If the load on each tire is well below the max, is increasing your tire pressure higher than 35 allowable?

Ive always been a max pressure guy, I run everything except my motorcycle at 35 psig. But with aldive going to 40 psig, it got me wondering about safe max pressures.

Does anyone else read this the same way? Or should it be seen as more of a load statement rather than a pressure statement. (I think this might be the case)

If the eighth alphanumeric in your VIN number is an "X" then you have an OHV engine. Example: 2FTBF25X5ELA000001.

The tires on my vehicles say max pressure 44psi

Since you have a 95, you have the OHV. The SOHC was not yet introduced that model year.

400 miles on I 75. Average speed 71.3 MPH ( via GPS ) Fuel used 13.5 gal ( Amoco 89 filled and refilled at the same pump ) MPG=29.62. Computer tune - Doug's Dyno Tuned 89 program.

See details of this acetone/fuel test at http://www.explorerforum.com/forums/...56#post1196756

A run to Atlanta, GA then to Charleston, SC, back through Newberry, SC to Atlanta then home will be done next week. More acetone testing will be done.

Just returned from a 1000 road Mile trip.

First leg of the trip - Sarasota to Atlanta [ 507 miles all I 75 driving ]
average speed 79.3 MPH ( GPS determined )
1 fl oz acetone/10 gal Amoco 89 gas
26.1 MPG ( speed kills )
The truck had 3 adults, 2 dogs, and was packed with "stuff"

Return trip = Atlanta to Sarasota [ 512 miles all I 75 ]
average speed 76.3 MPH
no acetone in gas
24.5 MPG ( speed kills )
The truck had 2 adults, 1 dog, and was mostly empty

The acetone in the gas at 1 fl oz/ 10 gal, yielded a 1.6 MPH increase in gas mileage.

I am impressed with the results in my truck. The mileage will definately be better with the speed at or just below 70 MPH.

On a recent trip to Naples, FL, a total of 223 miles, I averaged 32.7 MPG.

Good job Al. I wish I could get anything near there. Did the new taillights add any MPG?

Upcoming:

Latest addition in the perpetual quest for enhanced mileage is a new MAF.

When I dyno tested my truck with Doug Studdard ( http://www.bamachips.com/ ) ( http://www.explorerforum.com/forums/...highlight=dyno ), we tested a new MAF from C & L Performance ( http://www.cnlperformance.com/about.html ).

This MAF netted me 7 RWHP over the stock Ford MAF. I am hopping that its increased effeminacy will boost mileage.

I decided to purchase one and evaluate its effect on mileage. I am waiting for its arrival as I type.

Further reports soon ..........

I'm about to embark on the same quest but in my case it's the quest for 20 mpg... in my bone stock V8 4.7L 03 Mounty... I'm getting 18.0 mpg right now... wish I could do 30... probably with 4 cylinders turned off...

[davidmmm69]

after my 33's got put on my quest is back to at least 10MPG...

[coach_al]

Al..... I am new to this site and see some interesting posts. Your use of acetone is one of them. The first post in this thread is from 2/24/2002 and now we are in 2005.... It looks like you have had success, increased mileage and no problems over the past 3 years.... If this is true ( I have no reason to dispute you) why all the negative posts? I will wait on your response, I do 100 miles a day have an 02 V8 X to/from Miama. I get 16MPG. I drive off hours so I do mostly 70MPH... Only mod... K&N filter.... Thanks in advance for your work here

There will always be naysayers. Every advancement in any field is meet with robust naysayers,

The ones here are the ones who like to talk but usually do not do any testing and experimentation.

I am very pleased with the progress in the mileage department ( as well as in the power department thanks to Doug Studdard ). I keep an open mind and will thoroughly research any concept and if valid or potentially so, will give it a try.

As I understand, 1 ounce to 10 gals to start and adjust from there. Does it matter what Octane to use?

I first experimented with 2 oz acetone/ 10 gal gas nd then went to 1 fl oz acetone/ 10 gal gas. I got best results with the later.

I have not tested with 87 gas however, the results are similar with both 89 and 93 gas.

[spindlecone]

I wonder if Chevron knows about this, or Shell, Citgo Etc, if a major dealer could add Acetone to the blends and get 2% gain in MPG, they would take over the entire market.
In Calif alone where we use 46 million gallons of gas per day, the savings would be unreal

My improvements have been while using 87 octane Getty. I started with 1oz. per 10 gals and am happy with my results so I'm staying at that level. Highly cost effective for me.
