I usually get better with the power turned up and driving like a raving lunatic.

 

Sorry for the one liners. I couldn't post more than that.

 

Also, this was with a BRAND NEW fuel filter and airfilter. They both went in just prior to this tank.

Truck is at just over 29K, oil was changed at 27K. Royal Purple synthetic.

 

Test # 2........This might surprise a few folks. Pics to follow.

 

 

Moral of the story....I got 2.6 MPG better with the power CRANKED UP and it cost me 2.4 cents per mile less.

 

what was the mix of driving city/hiway...?

 

That doesnt make sense, but I agree with you. This past, 90% city driving, max RPM 1500, grandma speed acceleration, only got me 11.8 mpg hand calculated. Overhead said 15.7. Although I do not have my computer recalibrated for the bigger tires yet.

 

I have been hand calculating my MPG for the last year and a half.

The overhead is CONSISTENTLY 15% off (or worse). (IT IS NOT RELIABLE)

And I do know that if I stay under 70 and slowpoke away from lights, it makes a 2 MPG difference (or more)

I am seeing about 15-16 arrond town, 18-19 highway, and about 14 towing

also, did see a 1 mpg improvementafter I got about 30K on the truck

Truck is stock, so I don't know what will improve MPG except driving habits.

 

Almost the exact same mix as the last tank.

Only difference was that the highway mileage was all in one shot, rather than several 40 mile runs.

And I wasn't going slow on this highway shot, this was going up to Dave's to get my hood. [sm=badbadbad.gif]
