fuel mileage difference by small speed

Ryan,

I've owned my 2009 PreRunner V-6 since September and I average on Fuelly 20.1 MPG. 2000 rpm, as others have mentioned is the optimum point for fuel economy. I was disappointed the first few fuel-ups with the mpg, but read the posts here and followed the suggestions.

I also purchased an UltraGauge and I monitor my mpg with the gauge as a reminder.

 

I can assure you that shifting at 1500 will not lug the engine unless you are towing or carrying a heavy load.

 

Everyone's entitled to their opinions, no matter how wrong they may be...

 

You are not keeping the shifter in "4" instead of "D", right? As silly as it may sound, more than a few people do it by accident.

 

No sir. I made sure of that after reading someone else had been doing it.
