Only getting 16MPG on my new 2017 Tacoma TRD sport

I always thought that, too. But they did a mythbusters on it and it was bass ackwards. They drove two trucks, one with the tailgate open and one with it shut. The tailgate shut got better mileage. Because that extra drag pushed the rear tires down and therefore better contact.

 

17' DCLB 4x4 OR, running 255/85-16's no kind of bed cover and I routinely get 16.5. my daily drive is 24 miles round trip and 75% 2 lane hwy (60mph) with 25% in town.

 

There are alot of variables. First being engine break in but ide say your broken in at 4k. From what ive learned everyone gets different MPG. I have a 3” lift and 275/70/17BFG AT tires which are heavy and my highway best is 17mpg driving like a grandma, and normal driving i get 14-15mpg.

 

Only got 1500 miles on my truck and only getting 15mpg at best 16 not much freeway driving. Few traffic lights 45mph tops

 

I'm amazed with the amount of responses on here as OP hasn't posted a thing since this thread started.

 

He’s only posted twice

 

Just trying to help lol. Crap i remember when i forst joined and asked the wrong question with out using the “search” button. Mad hate

 

Whats your tire pressure? I just lowered mine a bunch before I filled up and there has been a noticeable decrease in my MPGs. Geting 16.1 average this tank compared to my normal 18-20

 

Well i was taught long time ago that asking questions wether good or bad is the only way to gain knowledge

 

What do did u set them to?

 

I went from like 37 to 30-32psi. Just trying out what feels best with my tires.

 

Wow 37psi got u better mpgs interesting!

 

Yeah! From what I understand, higher PSI should get you better MPG but will ride a bit rougher? Or is that not the case?

 

You are correct. Less rolling resistance with higher psi.

 

I knew a guy who set his to the max psi he never said how his mpg was but he complained about the ride lol. Has anyone ever seen a difference between ect on or off?

 

I never could get batter than about 17mpg in my '17 dcsb auto. I do drive mostly city though. Now with 265 70 17 ko2's, I get just under 15mpg regularly. I have doubts from people who claim 25+ in their 4x4 auto tacos.

 

If we are going to talk wind resistance then might as well add prevailing winds too. If you drive mainly north/south and prevailing winds are north in winter then MPGs will be lowers.

 

To a point, but traction suffers and tires can wear wrong. Use the correct PSI with necessary changes depending on things like off road, snow, etc.

 

Dang u... getting 2 MPG better than me.

 

I have a 2.5" lift and 275/70/17 tires and my average MPG is 13-14.
