2700 RPM = 75 MPH = 17 MPG

2007 DCSB 4x4 MT. Completely stock.

All freeway driving...constant 75 MPH in Sixth gear on flat freeway. This average over three fill-ups.

I knew I was buying a gas hog...This thing is FUN to drive though.

I feeling some 255/85's in the very near future to stretch that gearing out a bit.

Just FYI

 

Try doing 65 for better gas mileage. 17 is pretty decent for that speed imo

 

same mpg as your number of posts...

be prepared for the if you're going to complain about gas mileage...its a 4x4 truck...

I get a constant 18mpg all around...

 

75mph is not the speed to go if you are looking for better gas mileage.

Anything over 60mph and you are going to lose efficiency exponentially. I think there was a Mythbusters on this, also.

i avg around 18.3 over 36 fuel ups. click on my sig. same truck 4x4 6spd. but with 265/70/17 grabber at2's

 

It's wind resistance, not gearing, that's killing your mpgs at 75mph.

Taller tires won't help and might hurt your gas mileage.

Now, if you want them anyway for clearance or a look, that's on you.

 

That's about the mileage I get w/ 2.5" lift & 285's. I actually get better mpg driving around town than I do on the highway. Mainly because I refuse to be "that guy" doing 65mph and everyone has to pass me. Around here, if you're not doing at least 70-75mph on the highway you are going to get run off the road.

 

My post was simply informational...there is no complaint. I knew what I was buying.

I will be moving to a different tire for off roading purposes...I will also keep the stock wheels and tires for roadtripping, etc.

Again.....this thing is fun to drive! I missed the manual tranny as my last DCSB(2005) was Auto and then my 4runner(2004) was auto as well.

 

yeah the 6 speed in the new trucks is geared retarded. that big v6 does not need to spin 2700 RPM at 75 in over drive.

but even in my first gen 5 speed I get 21 MPG at 65 mph and 18 mpg at 75-80 mph so as was said before, its mostly the wind resistance.
