What perfect timing for a topic. Today is the first time I have let my fuel go so low as to activate the orange "LOW FUEL" warning in the messsage center. I was also curious to determine how much gas is actually left as soon as that light comes on. Here is what I found out:
My AV: ? ? ?02 Z66 w/ 3.73
Total Mileage: ? 2982 miles
Trip Odometer: ? 441 miles
Gallons filled today before pump clicked off: ?26.71 gal
Fuel needle position: right on "E"
Computed mpg: about 16 mpg combined C/H driving
So if the AV tank has a 31 gal capacity, then you can argue that maybe it has 3-4 gals left.
Like I said, this is the first time I let it go down so far. I normally fill tank back up at 1/4 level. I heard that the less "space" there is in your tank for condensation to take place, the better for your gasoline quality and your engine health overall. But carrying around a full tank all the time with all that weight around is also detrimental to mpg and performance.
This was a great topic and great question to ask. I am reading ALL the replies for sure....(plus I need a post to attach my next sig ?
Oh wow, I just noticed that I have now 501 posts ?
How can anyone have that much useless stuff to share?
My apologies to the board...
