400+ miles on a single tank?

I recently took a bit of a road trip over the Memorial Day holiday and suprisingly I was able to do it on one tank, with room to spare to drive to work and home yesterday.

I traveled from Denver to Steamboat Springs, drove around Steamboat for two days, drove back to Denver, drove to work and back yesterday for a grand total of 401.3 miles, and my trip computer still said I had 10 miles until empty. I used 87 octane (mid-grade) fuel. I filled up last night with 20.66 gallons equating to a gas mileage of 19.42 mpg for the trip, which consisted of about 80 percent highway/20 percent city driving. It should be noted, however, that the highway miles were mountain driving half on interstate, half on two-lane highway. I had to go over two major mountain passes each direction (which never saves gas). Plus, I drive like a maniac, passing people left and right so I'm very impressed. I'd say I averaged 70-75 mph on the highway the whole trip.

So how many miles have YOU driven on one tank?

When I went to the Outer Banks I traveled 426 miles on one tank. I averaged 20 mpg both ways, being good and using the cruise.

I don't think 19.5 mpg on the highway is unexpected. In mountain driving you may eat gas going up but you also save a lot going back down.

I generally get 17.5 mpg in my V8 4x4 driving a mix of highway and city streets in Fort Lauderdale, FL.

Did you do any off-roading on your trip? Pictures?

Sorry no off-road and no pictures, it wasn't that kind of trip. More of a golf/relax vacation. I'll have some nice mountain and off-road pics later this summer.

I'm usually around 17 mpg too with mixed daily driving.
 
I got 463miles to tank a month ago, on I77 and I81 through virginia. I have an 05 V6 4x4 SE, and generally drive hard, but for this trip the cruise control was on majority of the time at just over 70mph.
 
I regularly get 420-430 miles out of a tank (4x4 V6). The biggest problem is that the computer is no use at all in calculating remaining range so those last 20-30 miles can be nerve-wracking.
 
Since I put a 2.5 inch lift and 265/70/17 AT tires I haven't gotten over 320 miles to a full tank. Highway or city.......mine only has 1700 miles. Usually about 15 mpg

Can tires about an inch bigger and a lift really decrease mileage that much??

If my tires say the max recomended psi is 35lbs, is it horrible to try more (ie-37 or 38 lbs)?

v6 owners with tires bigger than stock, what is your record for a tank?

I love the truck, but I hope this improves some

Did you remember to factor in the fact that you are traveling 2-3% farther than you odometer reads because of the larger diameter tire? Don't inflate your tires to more than the max recommended pressure.
 
My consumption improved steadily as the miles rode up, it is better than it has ever been, now at 23,000 miles. However I am pretty certain that people getting around 20mpg averages do a signifcant amount of controlled freeway driving. I would say of a 400 mile tank I average 350 on freeway. If I fill up on a friday night and drive alot on the weekend, I get around 320miles to a tank (mostly because I cant resist thrashing it off the line, its fun and the best performing vehicle I have ever owned), or 15.5mpg. On that note, I dont know why they intentionally have an overreading mpg calculator, my previous vehicle, a jeep, was spot on, this overreads by at least 1.2mpg.

yeah, I factor the 3% increase. Thanks for the responses. I changed from 91 octane to 87 but I might go back to 91. I'm probably just being impatient

Highest I've gotten is 479.1, filled up with 20.627 gallons, MPG = 23.23 (V6 2WD).

Simply amazing! I'm glad I can break 300, coming from my daily driver that barely gets 280-290 (17mpg avg). Hopefully my 4R will get me 20mpg, I'll be happy with that. :)
 
On long trips, I can persuade my runner to get 25.3 mpg at a 70mph cruise speed. Never paid attention to how many miles out of one tank. Well over 400.
 
Best tank was last summer (haven't started the highway stuff yet this year)... 507 with the range showing 35 miles left (and no yellow light).. Filled up with 20.21 gallons (507 / 20.21 = 25.09 MPG)... I never get below 390 miles per tank (even in 4WD all the time in the winter), my commute is roughly 75% highway, 25% city.

Worst tank was 275 miles towing a 22' boat and trailer weighing just over 4500 lbs (filled the 4Runner with 20.1 gallons which equates to 13.69 MPG)
