I would use a full tank of gas to do tests with. it is the most accurate way to measure changes in your average mpg which is what you want not a 50 mile run with a fuel top up to see the difference, there is not enough time/miles to get accurate readings from the tiny refills..
Save gas
Ride a Mtn bike for errands exercise entertainment and outright fun
