Well, I know there are a lot of topics on the net about the Terrain/'Nox I4 not getting the MPG that it was rated for.
This weekend we made a family trip down to Nashville from Evansville, IN. Its not a flat route at all and there its nothing but rolling terrain.
I had just recently changed the oil to Pennzoil Platinum to see if would make a difference at all.
On the last trip down there (two weeks ago and weather was literally the same) I set the cruise to 71 MPH and the DIC read 27.9 MPG.
This time I set the cruise at 71 as well and the DIC read 29.3 MPG. The tires were at 37/38 PSI. With a little driving around town and about 60 miles back we stopped at filled up and I hand calculated 26.9 MPG and the DIC read 27.7. The MPH average was 46.9.
I them aired up the tires to 40/41 PSI and slowed down to 66 MPH for the return trip. The car averaged 63.4 MPH. The difference was pretty remarkable to me. The TCM downshifted FAR less and the car just seemed to be in the sweet spot.
The DIC read 33.6 MPG!!!![/color] Now, ours reads about 1 MPG too high so that is still REALLY **** good. If I had continued at that speed at on flatter ground, I would honestly expect to get 33-34 MPG. By the DIC calculations the range for that tank is right at 600 miles!
I wont have an opportunity to hand calculate as my wife will be doing city driving for the rest of the fill up.
Keep in mind, our vehicle has right over 3k miles on it now. There was NO hyper-milling at all, if I had, I would imagine I could get up to 38 MPG with a few cooperative 18 wheelers.
Take this for what its worth and your mileage may vary! [/color]
EDIT:[/color] Also, forgot to say, we had the A/C set to 67 with recirc ON, so it was drawing a lot off the motor.
