15-35% mileage increase

[aldive]

After noticing the swelling of the o rings when immersed in 100% acetone for 1 week, I decided to see how they would look after 1 hour in 100% acetone. I also immersed an o ring in 100% gasoline ( Amoco 89 ) for 1 hour.

The picture below shows ( from left to right ): 100% gas immersed, new, 100% acetone immersed.

The swelling after 1 hour appears to be the same as the 1 week sample. The 1 hour gas soak appears to be swollen, though not nearly as much as the acetone.

The elasticity of the o rings appears to be the same whether acetone swollen, immersed in gas, or brand new.

Next I shall immerse the o rings in the usage mix ( 2 oz acetone/10 gal gas ) and take a look at 1 hour and then leave for a week.

Nice results al. Why exactly do they swell so fast in acetone?

Albino 94LTD, you and Al Franklin have the best chance of proving or dissproving this idea.
I keep exact records of all of my refueling, as well as maintenance. Mileage changes greatly between tankfuls. The problems are that rarely will anyone achieve the Exact refill level as the previous tank, and drivind conditions are always different.

I can understand your concern here and I assure you that I had the same concern. I have worked in a variety of labs for years and can appreciate the need for accurate measurements. To that end I have used a marked wooden dowel as a dipstick and can, therefore, fill the tank to the EXACT same point by stopping the fill at the first tank cut-off, and then using an lab beaker to fill to the proper point on my dipstick. I then add the amount shown on the pump and the addition from the beaker to determine total fill.

The o ring on the left is a new one and the one on the right was immersed in the usage mix of acetone/gas ( 2 fl oz acetone/10 gal gas ) for 1 hour.

It appears to be no difference.

Edit- that first line in the quote is sigworthy if anyone wants it.

Al where did you get the O-rings you tested?

The morgue.

Is it just me or is there a color difference? (and is that normal with O-rings?) Keep checking those "marinaded" rings to see if the acetone soaked ones dry out faster or if there''s any other effect on them after time.

Look 20 posts back Nate.

Look 20 posts back Nate.

i doubt jamest would mind if we share. 'sides i've seen at least one other person with it LOL

as far as the Topic goes, i am holding off this trial until i can get more accurate results. This is what i had in mind. just gotta find a spot to mount it and paint it black.

Yes there is a color difference. In chemistry we would use something known as the pickling process. What happend is the acid is reacting with the oxides in the O-Rings and they got darker. I wouldn't suggest putting anything zinc or aluminum plated into acetone either.

ok good job, his avatar is kinda creepy anyway...

Heres another creepy picture of him when he went on vacation:

 

[aldive]

I just went and looked at the o ring that was so swollen from the acetone bath ( its a little over 10 hours after removing from the acetone ) and it has returned to virtually the same size as a new one.

I just poured gas into a styrofoam cup, and it dissolved it!......That's it!...I'm never putting gas into my truck again!. :fire: ...It might wreck the fuel punp, lines ect.....

haha, just as a disclaimer, gas+styrofoam= :fire: that sticks to anything and burns for a very long time.

idle hands are the ...what?

 

[off-road97Xplor]

Gas + Styrofoam is how you make Napalm(spelling?).
If you light it, it burns long long time.

Napalm is mad with soap and gas.
