How many miles on 1 tank?

[D'Hag]

My "Range" output on the dash, added to the trip odometer, consistently adds up to 430 miles.

From fill to when the fuel light comes on, I get right around 400 miles on a tank. MPG averages just over 16, mostly Interstate highway driving at 65-70 mph.

Lol.. yeah, no driving like an ass.

Well maybe my truck is not being as gas efficient as it could be? I have read of people getting 19-20 at 55 on the freeway. I've managed to get about 17 on those stretches...:ack:

If we drive only on our 2-lane highways at 55 mph, mine averages just over 21 mpg, and has gone as high as 23 mpg. On such trips I get a little over 500 miles on a tank.

Only mods (so far) was a K&N filter (not the intake kit) and a set of Bosch Platinum+4 plugs. Each improved the mpg. The two mods combined upped the mpg by better than 25%.

Oh... and I save "driving like an ass" for my Firebird, which is built for it.

Damn, I only get 200 out of mine!

How come my 2014 Tahoe LT would say I could go 482 miles on a full tank but this 2014 will only go 419? Any comments?
