01DodgeRam360, no offense, but you need to stop looking at what that computer is telling you.

If you only get 300 miles to one tank of fuel, you are getting an average of 11.5 MPG.

26 gallons is what the fuel tank is on a 2nd Gen Dodge Ram 1500 quad cab/extended cab. So you take 300 / 26 = approximately 11.539 on average.

 

Jason W dont mean to burst you bubble but he s prolly close to the mid 14's most of use get gas when our gas light comes on. That always leaves 4.5- 5.1 gallons in the tank.Im sure hes not running it bone dry. So your 300 miles / 21 gals to fill = 14.28 mpg

 

Maybe our trucks are designed for 55, I have no idea.

My grandparents figured out that their 2003 300m got its best MPG at 63mph. So thats all they drove, interstate or highway, didn't matter. Drove me insane, dangerous to drive that slow on a 75mph speed limit interstate.

I bought the truck for its image, power, and 4x4. Not because it gets great gas mileage. You guys drive what you want, I will always be driving 80 in a 75 and 70 in a 65. I'm not a danger to anyone at that speed (anymore than normal, anyway ) and I get where I'm going a little faster than most.

EDIT: I'm just going by what he said. You may be correct, if he didn't go bone dry, than yes, of course. But he said 300 miles to a tank, so I took him literally. He can clarify when he logs on next.

 

But the wind resistance part is true. Over 60 mph your engine is working harder to cut through the air than any other single reason.
Like Cartman typo'd put your hand out the window & feel the wind push it back.

Lucky Gen 2 trucks are one of theslipperyest? (did Ispell that Right?) aerodynamic? trucks on the road.

Slipperiest isn't a word to my knowledge, yet my spellchecker says it is. Interesting.

I've always said "the most slippery", but it appears that may be grammatically incorrect.

With the new 4th Gen Rams coming out, that claim may not be true much longer. I've heard good things about their aerodynamics.

 

yeah I think Joes numbers are high on his computer too. I thinkj he should do it by hand after getting the speedo calculated. The overhead consoles are usually off a fair amount.

 

Im lucky if I can get to 80MPH... I sure as heck can't hold 80 at the slightest hill. Hmm... LOL but I get crap mileage. I wonder how clog'd that cat is after all (seriously).

 

You seriously can only get up to 80mph? Something is wrong with your truck it should be able to go way way faster than that.

 

The overhead computer may be off a fair amount, but it is an apples to apples comparison for where you are getting the best fuel economy.

4.10 gears in the rear of mine gives me the best economy at right around 61mph for highway cruising. The computer bobs right around 20 mpg on flat road. At about 47mpg, I get 22-23 mpg on the computer. If I hover around in the 50s or go up to 65-70 mph, then my mpg's drop to around 16-17. I don't doubt that these numbers are inflated, but by driving around these speeds I've been keeping my need to fill up at further intervals than I used to.

It's all about what RPMs the engine pulls best in. Best advice I can give is keep your foot out of it when you accelerate, and keep the truck in the spot where it feels like it's floating and barely working at all and you're getting the best MPG's you can get on these bricks.

I don't doubt also that not filling up to full (especially on my 35 gallon tank) would help by reducing the truck's weight and increasing MPG's.

 

it all depends on the truck guys, gearing, tire size, milage on the motor. A number of things. I think you are all right[:-]
