    Thanks for the info Bob! Still have 7miles till empty =) Hoping I have a scan tool tomorrow to check fuel levels and fill the gas can as well. I know it sounds dumb, but I am having fun with it.

    Congrats.

    Your fuel up continues to support the 10x displayed as a reasonable estimate of when to fill up. It would suggest that at ~ 592 miles you would need 10.5 gallons of gasoline. The extra 9 miles would consume about 0.2 gallons, which would leave you estimating that you would need 10.7 gallons. You used 10.8 gallons. Pretty darn close to the theoretical estimate.

    I have the Scan Gauge II in now and this tank I think will be lower. Waiting to see what my final numbers are.

    Assuming you had a complete fill up when you started this tank and that you maintain your 60.5 mpg, I expect you would hit 600 miles and only fill up with 10.4 gallons of gasoline.

    Interesting, on fill up, the ScanGauge saw 11.5 Gallons of Gas not 11.9.

    Oh and when i went to the gas station I was only able to fill up 9.6 gallons?? That means i could have passed 600 easily :mad:
    I only went 10-15 miles after my DTE showed zero

    Your real mpg was probably around 58mpg. So figure 11.5 x 58 = 667

    Yes, but how can you know how much you have left? It's better to use 11.5. My Scangauge at a full tank says 11.5 Gallons. Are you willing to risk it? =)

    You can use a quick formula (see my post #29 above) of 10x displayed Cons. will equal how far you can go using 10.5 gallons of gas (leaving ~1.4 gallons in reserve).

    10 x 60.2 = 602 miles/10.5 gallons = 57.3 mpg (calculated).

    You got 551.8 miles/9.6 gallons = 57.5 mpg (calculated).

    Yes, you would have hit 600 miles easy. Next time you have the Cons = 60 or better you'll know you can drive 600 miles on that tank.
