so we have a 20 gal tank. I believe we have a 3 gal on reserve?
So, if I reset the gas meter thingy to ZERO, do I stop after the gas light comes on? and would that be at 17 gal??

 

anyone know?

 

I don't know what you're saying.

basically how do you measure your MPG?

 

Oh....

Fill the tank. Drive. Record number of miles driven. Fill tank again. Divide number of miles driven/gallons of gasoline used.

 

see, that's the thing. The Z has a 20 gal tank. so when the gas light comes on, is that at the 17gal point mark?

 

When the LOW FUEL warning light come ON, I drive to a gas station a fill up. So I haven't tested how far you can drive with the light ON.

 

you are completely right. The gas light comes on early and your dte will flash at you. I have driven over 50 miles with my dte at zero and my light on. You are exactly right...20 gal tank, check your avg. mpg and do the math on how far you can really go. I was on a road trip when it happened to me and didn't even worry about it.

 

Don't worry about how big the tank is. Fill up the tank. Record current miles. Drive. When close to empty, refill tank. The pump will tell you how much gas you just put in there. THAT'S the number you use to determine your mileage, not what Nissan says the tank holds or what you think the tank holds. If you drove 400 miles and put 15 gallons in the tank, you were getting 26.7 MPG.

Make sense?

 

The old 300ZX's used to have a seperate guage for the reserve tank after the light came on. No such luck for us.

 

why do you guys let your gay go down its really bad for you car i hear. it collects all the junk from the bottom of the tank. i never let my car get low on gas.

 

DTE comes on with 5 gallons or so left in the car... i think thats quite a bit to leave just sitting in there..

 

Ditto .... What Gryphin says has been my experience. ~ 4.5-5 gals left when the light starts to shine. For me that is at about 400miles if I take it easy.
