20 mpg

With my 4.0 DC I am getting a consistent 21+ mpg. Its just about the same MPG as my 2003 Tacoma with the 2.7.

 

Cold weather problem is probably due to Transmission getting over cooled.
Our trucks don't have thermostat in the transmission, so they always send tranny fluid through both radiators even if engine is not. That just brings Transmission fluid to some crazy low temperatures.
Other Toyota vehicles dont send transmission fluid to radiator until 190F and fully open at 220F (on Toyota WS fluid).

 

I just make it to 17, that is city driving with a 4x4.

 

Same here, 18 to 19 in the winter, 19 to 21 now. 2012 DCSB TRD OR. Going from the Rugged Fails to Michelin LTX AT2's did not really have an effect.

 

That's pretty much what I'm seeing.

 

20.3 using regular, just about every tank give .1 or .2 if highway speeds increase

 

Same tire size I assume?

 

What program are you using? Is this going through your OBDII port?

 

Mine too. Just hit 21.3 last tank.

 

20.4 last tank

I think all vehicles like the summer blend of gas ??

 

Yes, same tire size, but I put them on the TRD fake beadlocks (FJ Special Edition, half an inch wider wheel, and I think a different offset). The Michelin tread seems a little more aggressive, although noise level seems about the same.

 

I use an Android App called 'Mileage' by Evan Charlton. It's good for history tracking and totals. I also use the 'Torque' app with a bluetooth OBDII scanner. It's great for live info, but it's not as detailed for historical data.

 

Awesome. I was looking for a good OBDII plugin and found this:

Automatic (Link1-ON White Smart Driving Assistant

Automatic Smart Driving Assistant

Looks like it has a lot of potential but doesn't look like there is many features yet.

 

Last tank I average 23.8. About 85% on the highway.
