Do you resist the urge to prematurely top off?

Gas light comes on ~60mte, at 40mte car won't move, avg fill up around 70mte (miles till empty). The info display fluctuates a lot, ie at 72mte it may go up to 80/90mte if I'm not at a light or traffic, in traffic or a light it will go down to 50/60mte but no e light.

I try and wait till just above empty. I have an 11.9 gallon tank and usually squeeze in 10 or so gallons. I figure running as long as I can on less fuel mean less weight I am carrying around.

I've been too lazy to track gas mileage for a while but I let the light turn on before I fill the car up.

With a 200 mile range and few - real, i.e. CNG - gas stations around, I fill up when I won't be near one again within the remaining gas range.

The average fuel consumption may be way off, the remaining range is just about spot-on ...

Obviously, I try to avoid running the Dwarf on its 2,5 USGal petrol reserve tank.

I fill up at gas stations that sell good gas at a good price, when my travels take me by them, when I know I won't go by them again before I run out of gas.

Did that make sense to anyone else?

I generally fill at 1/4 or less. This gives me the ability to buy the cheapest gas I can find.
As a general rule that's Wal-Mart, but after they dropped the 15 cent discount I have been buying from other stations. The Fiesta was filled at a Shell station in Gloucester County for $3.229 and the bike was filled near Hopewell for $3.199. One of the workers at the machine shop in Hopewell told me he paid $3.089 for his last fill. Maybe the next time I got there I'll take my 3@5 gallon gas cans, fill them with exactly 5 gals and then top off locally. That's almost 30 cents a gallon cheaper than I paid recently, but I don't drive-ride very far just to get a few cents a gallon off on gas.

1/2 tank for me. Religiously.

[Frank Lee]

Well what can you say about religion.

If I'm commuting to work, and the "50 MILES TO E" alarm goes off BEFORE I reach my normal fill-up station, I fill-up. If the alarm goes off AFTER I pass the station on my way to work (or on my way home), I fill-up the next day on my way to work. If I'm starting on a long road trip, I'll fill-up. Otherwise, more fuel than I need for my current trip is unnecessary weight. YMMV

On the truck I go until the EMPTY light comes on. The rest of the gauge doesn't work right, so the needle points to E for about 400 miles. I'd replace the gauge but because of the way the tank's mounting bolt threads have failed, I can't get the tank down. I'd have to pull the bed. I just don't want to do that.

On the Honda I'll go until the light comes on or until I've cracked 400 miles on the tank and it's payday, whichever is first.
