How large is the "reserve" on the max?

A couple of weeks ago, I drove about 450 miles and the "low" fuel idicator was on for at least 25 miles before I refilled. If I remember correctly, my refill was 15.7 gallons.

That must mean you have abut 5 gallons left as soon as the first legitimate 'low fuel' warning light comes on.

 

Older cars have two resistors which serve as the indicator points for full and low...it's entirley possible they have a 3rd value for the 6th gen.

 

IIRC A34's have a 20.5g tank.

 

prolly 2 gallons .. . everytime i refill, just barely over 16 gallons at most.

 

I'de love to get this answert as well. I drove my 07 until the light came on. My NAV said I had 43 miles left. Then at 20 miles the NAV changed to read **.** miles left. I went another 10 miles to a gas station and filled up and it only took 17 gallons. I thought these cars had 20 gallon tanks. I am guessing a 3 gallon reserve, which seems like a lot to me. I'll have to dig through the owners manual next week after my hernia surgery.

I think the term reserve here is being misused. Typically it's 2.5g, but the level sensor may read differently due to uneven ground surface etc.

Instread of finding out, just add some fuel when you need it and don't run it too low.

FWIW, trip readout is inaccurate. I got 81.6 MPG one day

 

4 Gallon reserve.

 

I didnt use the trip readout. I used the basic odometer trip and I also just recorded total odometer miles traveled for that tank.


Also, I just verified, that when I went to refuel that day I filled up with 15.24 gallons after traveling 448 miles. Not too shabby for a commute that includes 80% highway, and decent stop and go city driving! That equals 29.396

 

My light goes on with about 5 gallons left everytime. At first I thought it was wrong but after 20 fill ups all the same and checking other maxs/altimas I realized it was right. I think Nissan is just giving a LARGE amount of wiggle room. The DTE is very conservative because Nissan doesn't want to be sued when you run out of gas with 10 miles left on the display. The *** is just saying that it's low enough that I will not calculate anymore. The 4 gallon reserve sounds right when you look at all the facts.

 

I have a 16 gal and 2 gal reserve but I never run below a quarter.

 

I wish.
1.) I have an 18gal tank...
2.) But it goes 'dry' after 16gal
3.) Have yet to see the fuel light
