Why the top fuel level bar lasts so long

[DebbyM46227]

I never let my car run out of gas, but I have the same thing as AAA included in my car insurance. It covers towing, flat tire changes, locksmith, battery jump-starts, and fuel/fluid delivery for $2.00 addl. every 6 months. So far, haven't had to use it with my Yaris for anything (knock on wood) but when I had the Cavalier I took advantage of it 3 times for flat tire changes.

Trying to get my UltraGuage more accurate as it relates to MPG.

Currently it is set-up to an 11.1 gal. tank.

I always fill to the first click, round to the nearest nickel.

Based on CTScott's examination and testing I am thinking of resetting my tank size to 11.9.

Would I be correct in assuming that a first click fill up would add an additional .7 gal.,apprx.?

Or would increasing the the tank to 11.6 an additional 1/2 gal. be closer?

I am thinking .8, any thoughts would be appreciated.

For the first click, I would say that 11.6 - 11.7 is good. If you go a bit beyond that then 11.8 to 11.9 would be appropriate.

Thanks Scott.

I think I will try 11.6 for a bit and compare to actual at the pump.


EDIT note: Would I be correct in assuming that a first click fill up would add an additional .7 gal.,apprx.?

That should be ".8"
