How is this hedging? You're making more trips to the gas station even though you're spending less each time, regardless of gas prices. It's the same if you were to fill up a full tank instead of half.

More gas at a higher price.

And I think i was a little misleading in my post. The light comes on with 2 gallons left, so you can go about 50 miles before reaching E or 0 miles on your screen. However, lexus dumby-proofed the car so there is an addition 2 gallons reserve after you get to E or go pass the 0 mile mark.
So when the light in your car goes on, you really have 4 gallons left (2 gallons in tank, and 2 gallons in reserves; you used 13 gallons of your 17 gallon tank), and after you ran down to 11 miles, you basically have what you estimated left: 2.7 gallons (used 14.3 of your 17 gallon tank). So when you went to fill up, you only filled up around 15 gallons. Again, these numbers are based upon a 25 mpg estimate, your car might not do that so the numbers might be off a little bit, but hopefully you get the gist of it.
Ah, it all makes sense. Thank you for the info.Originally Posted by edgeucated

There's no way to "hedge" against gas prices, unless you stop driving. Cars need gas regardless of price fluctuation.Originally Posted by Joe Z

It's like hedging against food prices. do you eat less when food prices go up?

I do the exact same thing especially in the summer time. I keep the weight down just incase someone needs to be put in there place.Originally Posted by anxiouz
Am I the only one who fills up only half a tank of fuel per visit? That's my way of keeping the weight down since my belly makes up the difference .

This is my experience as well. The light comes on and you've still got a pretty fair distance to cover before you run out of fuel. I once put 16.1 gallons in the tank. It had said 0 miles to go for almost 50 miles, but I was in the middle of rural Illinois in the middle of the night and options for fuel at that hour were few.Originally Posted by edgeucated

This could be possibly Lexus's way of keeping the engine on. S2000's are known for having their engine shut off during high G long left handers when their fuel is low. This could make sense in a performance aspect when the IS-F is at the track, having a few extra "reserved" or uncounted for gallons of gas can help provide for fuel pump reasons.. especially if the fuel tank baffling is not that great.

Inside the fuel tank, an offset high-output fuel pump and a sub-tank help prevent fuel starvation during cornering maneuvers.

There's a few gallons of "reserve" fuel before its completely gone. manufacturers do that to idiot proof it a bit

zero on my range.
Toyota wants a couple of gallons of fuel left in the tank to cool the "in tank" pump. That is good since dropping the tank to replace the pump is not easy and not cheap. Add fuel when the gauge is low.
We had a Mercedes Benz customer that always drove his car on empty. Can't recall for sure but his relatively new car required three to five new "in tank" pumps. We told him, but he never got the message. Of course it was the manufacture's fault.

The ISF's pump is accessible by pulling up the back seat cushion. No need to drop the tank.
