Shooting for 400 mile/tank

Like many of the folks here, I seemed to be getting crap mileage. 200-250 miles per tank. I read all the posts and filled up my truck with 17.5 gallons of 87 from when the light went on. Feathering the gas pedal like I was goosing a butterfly. Doing my best to keep the RPMs around 1500. It's hard 'cause I feel like grandma creeping off the line, but at the same time, I was surprised at how quickly I got up to 40-50 doing this.

So far 100 miles from the first 1/4 tank. Wish me luck!

 

I get 425 miles out of my tank

 

i got 400 driving for 10 hours to NC and back, all highway, 70+mph, 4 people, bed FULL.

bu i usually get 250-300.

 

250-300 is usually what i get.. my light comes on at about 250 though and when I fill up it only takes about 17.5 gallons.

 

I'd be happy with 300. But the bragging rights from 400 would be sweet

 

Ive been watching my driving very carefully lately and I average 19mpg. the best ive got so far was 341 out of a tank. I dropped my speed from 70 down to 65 on the highway, that has helped the most. I coast to stops. turn your truck off as soon as you get to your parking spot, dont let it idle for any time.

I do need to add about 5psi to all my tires and im thinking I can get up to 20mpg. Im so close! haha

 

I have done it several times in my 6cyl. I shift before 2grand and stay light on the gas. Also 60mph is about as fast as I would go if I were trying to get 400 miles. Its not fun to drive that way so I stopped doing it.

 

I drive 90% highway, 40 + miles each way to work and back. The stop and go kills me, but I consistently hit 360-370 before light. Best I have done is 385.

We have had some HORRIBLE wind lately, but I did a jaunt about 130 miles away, and on the round trip (73-75mph each way) I actually got worse mileage, even all highway. Seems the sweet spot (traffic + gas mileage) for me is about 66-68mph. Keeps me at a safe speed, and decent mileage.

my current average is about 21.1mpg, on 8 fill ups

 

My biggest challenge has been keeping it on road!

 

i got 400+ on my way to alabama but that was straight driving with five ppl in and a full bed of climbing gear. What made it better was i didn't pay for gas at all and had at least 6 fill ups to go from south FL to way North Alabama. but now that i am back i'll be lucky if i get close to 300-350.

 

I have been using ethanol free gas too. this tank does have ethanol though so we will see if there is a difference

 

where are you finding ethanol free gas?

 

where can you get ethanol free gas???? just wondering cause in FL its impossible.

 

This is a short term goal of this endevor. 17.5 gal/miles driven at the time the light goes on.

 

i got 290 (F-E) with 3 in. lift & 285s this past tank...but i regeared last week

 

I get 410 miles per tank no problem. I got a K&N filter and then took out the CF, that helped a lot. The other part of it was my driving, I drive 50/50 freeway/city, but especially on the freeway I keep it at 70 and get good mileage.

 

Fuel mileage depends a lot on how you drive...

According to scanguage my best average was 28+ MPG but it was mostly down hill.

Thats DC/LB 4x4 4.0L Auto

My average/average is between 20-23 MPG , My wife's average on the same truck/ same driving location is 14-16 MPG
