Step 7: Results
The electrodes lasted for half a tank and I got 500 miles out of it. Assuming I got 200 miles out of the other half as usual: 500-200=300 300miles/6.5gallons=46mpg
46/31=1.48 thats a 48% increase in fuel economy!
-With the graphite I got 510 miles out of a tank. 510/13=39
39/31=1.25 a 25% increase in fuel economy. I'm sure that if I increased the size of the electrode the mpg would increase. The pencil lead is just so small. I will update again.
P.S. My wife ran off with the camera to a florida vacation in the middle of my build. Thats why there are no pictures of the graphite electrodes. When she came back the camera wasn't working.
