Gas mileage from earlier 2nd gens to the new 2nd gen

So I've seen numbers where dealers are saying the 13 tacoma DCSB 4x4 with the 4.0 is getting 21 hwy. But I could of sworn that the earlier 2nd gens in same setup where at 19.
Do I have the numbers wrong, or has toyota tweaked a few more mpgs out of the V6 over the years?

 

my 06 was/is rated at 20 mpg hwy.

 

My 06 manual was rated at 19 highway. I think the autos were 21?? But i don't know for sure since i didnt look at any autos!

 

I get something like 18 average so I would say the numbers are a little tweaked

 

I have an 07 getting 20 average. It really is just how you drive your truck. You can buy a 2013, drive it like you stole it, and see 15's and 16's or drive it like you are taking it to a nice seafood dinner and see 20+ numbers.

 

I usually get around 20 mpg if I take it easy on the gas petal. 2009 TRD OR

 

I believe he is asking what your windows sticker stated on the truck. Mine is a 2011 DC V6 Auto and it was rated 16/20. You can also check out this site.

I see my 2011 has the 16/20 and your 2013 has a rating of 16/21. Maybe they turned the truck around and drove with the wind?

 

Lots of comparative data here:

I regularly get 22-24 mpg out of mine (depending on if my wife drives it or not) but I'll add the caveat that I drive "mostly" country back roads and it spends less than 10% of it's time above 60 MPH. I don't remember what my window sticker said but it was probably around 20 MPG I would expect. The most that I ever got out of it was a little over 25 MPG with a strong tail wind in Wyoming and the least was 18 MPG with a strong head wind in South Dakota.
