There is about 2 gal in reserve on our cars.

 

Hmm I'm not sure what my mustang gets. I know I put about 6 gallons in it yesterday drove about 80 miles mostly highway "hot rodding it a lil bit" and I had to put back in becuase it was almost on E again. Thats a carbed 5.0 with a cam running rich.... high geared rear end...

 

So, if there are 2 gallons in our reserve, does that get used if we're on empty?
