* 3 tank avg of 37.35 mpg concludes an A-B test of a cone filter for a 6.7% mpg gain from last summer's ~35 mpg avg.
notes:
1) warm air intake was not an issue....since intake air was already being drawn from under the hood with previous setup
2) warmer ambient temps not a factor due to not using AC and driving usually in temps under 85 F.
3) it's possible that I was trying a little harder with the driving techniques
4) with the last refill...the gallons used was close to right on...so the need to readjust gallons used DOWN as seen with previous 2 refills was not seen this time
Basic science? ...try something to see if it works....
THEN try to explain it? Don't try to explain it before you try it?
While you (?) can still argue about it for whatever reasons...understand that I'm still seeing a 6.7% mpg gain. So there....
