@Top_Fuel, question about refuelling (How are you often adding 31L to a ~28L tank?)

[Space Wolf]

When looking at the fuel economy logs, I saw that you often manage to refuel 31L (8.2gal) or more. My car says the tank is empty at around 28L (7.4gal), and the 'estimated km left' gauge doesn't express an opinion anymore.

So how do you manage to refuel at 31L or more and never by accident drive it empty?

I've noticed the same thing on Speck. It reminds me of the 'reserve' portion of a motorcycle fuel tank - it's a margin of safety.

My car is moderately consistent with fuel mileage. I sort of know how many miles to expect out of a full tank. When the gas gauge starts doing its crazy-blinky mode, I stop paying attention to it and I will flip over to the trip odometer. When my trip mileage goes beyond 400, I start thinking about getting gas because I know I have burned through approximately 8 gallons at that point at roughly 50mpg.

I know that's not very scientific, but it's working for me so far. But now that I've said that, I will probably run it out of gas next time...lol.

Each bar represents a gallon, 8 bars, plus 9th flashing bar your last gallon, flashing gas icon perhaps your last 0.2 of fuel? Not sure.

No, when its flashing it still has at least 1.5 gallons! I've only filled up a couple times when it was flashing and I still only put 7 some gallons in. I've never once put even 8gal in.

Your car must be different than mine. I've let my car get low enough a few times for the lights to start flashing. It took something like 7.8 gallons to fill the thing up. Scary business right there.

I'm confused. Look like we have similar results lmao. These cars have 9gal tanks. So by your own experience you have close to 1.5gal when its blinking.

Living on the edge big time.

Some folks go skydiving or swim with sharks for thrills. Not us.

[Dirk Diggler]

Ahh, so its just overly conservative to prevent folks from running out of gas.

[Pryme]

I always fill up around 6.8-7gal.
I never like to bring it too low.

A habit I learned from a couple mechanic friends, letting it get really low all the time is bad for the fuel pump if it uses the fuel to cool itself off. A lot of fuel pumps are in the tank.
I'm actually not sure if the Mirage is like that or not but My habit remains.
