I'll keep this updated, but what are your thoughts on this?

Please note the gas prices varied around 3 cents and driving style was the same.
Calculate it by hand and post results.

This would tally around $38.XX (CAN) to bring the guage back to full. Therefore, driving to work costs approx. $38.XX

- During the week, I would notice that my gas guage would take awhile to come down from the FULL position (e.g. 3 full days of driving), but once it reached halfway between FULL and 3/4, the guage would lower quicker and stop at a tad under 3/4.

- I decided to perform a little experiment. I filled up my tank and waited for Monday morning. I then drove until Wednesday afternoon where I filled the tank back up - $16.XX to bring to FULL. On Friday afternoon, I then filled up the tank again to wait for Monday 14.XX

- So the first time, I noticed I saved $8.XX or so dollars.

- I ran the same experiment and noticed I was saving between $8-9 dollars a week by topping up the tank in the middle of the week.

I think that since he's using the cost of gas used during each weeks commute, and has a pretty fixed route, that's why he feels he's gained all of this fuel economy. I still think he should redo the test with full tank of gas with 1 fillup, record the km's driven, and the liters of fuel used. then the next week should be the 2 fillup method.. again recording the km's driven and fuel used. That way, gas prices are no longer a variable/how full the tank is at start of week isn't a variable/and distance is no longer a variable.... fuel economy would be measurable.

you need more weeks of testing before jumping to a conclusion
