200 for 3/4 of a tank average.

26 gal. tank.

if i let it go below a 1/4 tank itll cost me 70+ to fill up

 

200 miles per tank. 26 gallon.

i fill up when the gas light turns on which means i still have about 5-6 more gallons. so its 200 per 20 gallons give or take.

 

i have a 32 gallon tank, dont remember miles to tank, but i know its more than that for mine,...stock

 

290 to 300 for about 22 gallons : which is about when my fuel warning light come on (26 gallon tank). All stock.

 

a little over 300 with some highway driving, a little under for all city. on about 22 gal. that's when my low fuel light comes on.

 

alright so im not too far off yall... prolly that extra weight from the HD. thanks yall

 

I forgot : don't forget to allow for different size tires.

 

Long box has a 35 gallon tank.


I can hit 450 miles with my fuel light on and sucking fumes. I just filled up from a half tank and averaged 7.69 miles per gallon. There are a TON of hills around here. But you know what, life goes on. Get over the fuel usage. Get a Kia or Prius if you want 896459782485745 miles per gallon. This is a truck. Drive it. For me, I think the cost is worth it. I'd rather feel safe driving a 2 ton truck getting 8MPG instead of saving a couple dollars in a tin can while putting my life at risk with all the 2500 Heavy Duty trucks driving around now. I value my life.

 

1. If you had a misfire, wouldn't it be throwing a P-code or check engine light? I know for sure that you would feel a misfire.

2. How much extra weight is there from the HD package? I know that it has the HD T-case which is close to the LD and a couple of extra leaf springs? What else am I missing? (Let me clarify that I am not comparing 1/2 ton to 3/4 ton. I just want to know where the weight difference between a 2500HD and 2500LD comes from. I don't think it can be a whole lot.)
