Acetone on fuel

I saw a thread on MCP about putting acetone in fuel, the benefits of acetone caught my attention and got me interested. After reading the article, I find it very interesting but still a sceptic, since acetone can melt or dissolve rubber I was afraid to try it at first on my motorcycle since the fuel lines are made out of rubber as well as some gaskets in the carb.... takot ako baka matunaw and eventually mag leak ang gasolina, but curiousity got the better of me and what better way to test it is to try it first hand... but before I did, I made some research on the net... nag google ako for acetone use on cars and was amazed that alot of people are using it on their vehicles and with positive results... though convinced but still a sceptic, I decided to do a little experiment, to try out its effects on automotive rubbers... I went to the nearest motorcycle shop and bought the cheapest fuel hose i could find, I increased the ratio of acetone per liter of fuel in order to simulate any worst case scenario, I placed around 1ml of acetone and 5ml of gasoline (the suggested ratio is only 1/15th of 1 percent-see figure below) in a small glass container, the ratio I used is 20% acetone per liter of fuel or more than 100times of what is required. I then placed the rubber fuel hose and rubber gasket inside the acetone/fuel mixture, shook it a bit and left it for a 3 weeks. 3 weeks later, I checked the rubber fuel hose and rubber gasket to look for any damages, breaks, cracks, swellness etc... but could not find one.... now its time to try it! masubukan nga!


How It works:


Complete vaporization of fuel is far from perfect in today's vehicles. A certain amount of residual fuel in most engines remains liquid in the hot chamber. In order to be fully combusted, the fuel must be fully vaporized.

Surface tension presents an obstacle to vaporization. For instance the energy barrier from surface tension can sometimes force water to reach 300 degrees Fahrenheit before it vaporizes. Similarly with gasoline.

Acetone drastically reduces the surface tension. Most fuel molecules are sluggish with respect to their natural frequency. Acetone has an inherent molecular vibration that "stirs up" the fuel molecules, to break the surface tension. This results in a more complete vaporization with other factors remaining the same. More complete vaporization means less wasted fuel, hence the increased gas mileage from the increased thermal efficiency.

That excess fuel was formerly wasted past the rings or sent out the tailpipe but when mixed with acetone it gets burned, though the engine still thinks it is running straight gas.

Acetone allows gasoline to behave more like the ideal automotive fuel which is PROPANE. The degree of improved mileage depends on how much unburned fuel you are presently wasting. You might gain 15 to 35-percent better economy from the use of acetone. Sometimes even more.


Now on to the good part! putting acetone on fuel...


What you need:
1 5ml syringe
1 Bottle of pure grade acetone - I bought mine at Mercury Drug, Apollo ang brand



Measurements and Ratios:

Figure 1:
Percentage MILEAGE GAIN when a tiny amount of acetone is added to fuel. The curves A B C show the effect on three different cars using different gasolines. Some engines respond better than others to acetone. The D curve is for diesel fuel. Too much acetone decreases mileage slightly due to adding too much octane to the fuel. Too much additive would upset the mixture ratio because acetone (like alcohol) is a light molecule and tends to lean the mixture.
The measurements from the chart are shown in ounces and gallons, the ratio is 1 ounce per 10gallons of petrol (minimum) with optimum percent gain at 3 ounces per 10 gallon (maximum for petrol and 2 ounces per 10 gallons on diesel engines).

The ratio of 1 oz. per 10 gallons is equivalent to 0.78ml per liter in metric (unit of measurement sa pinas), so based sa chart sa taas, 0.78ml per liter ang minmum (1 oz / 10 gal) at 2.33ml per liter naman ang maximun (3 oz. / 10 gal.)

Adding Acetone to your tank
Simulan po ninyo muna sa ratio na 0.78ml / liter, then take note of the power increase and mileage till the next gas refill, sa ratio na ito rin ako nagsimula, increase the ratio to 1.5ml / liter on your next refill and take note again the mileage and "feel" ng hatak whether mas lumakas pa ng onti from the 0.78ml / liter ratio, do the same with the 2.33ml / liter... after which see kung saang ratio "happy" kayo at ang MC nyo...

Maximum percent gain on my Shogun R is at a ratio of 2.33ml / liter, all smile kami ng Shogun ko sa ganitong ratio! As for my new Raider150, 1.56ml ang tamang ratio.

Note: The effects of acetone is negated when used fuel with ethanol (E10).
