Most Effiecient/Sustainable Driving Style

Well your rpms are in the optimal torque range, but if your going up a big hill or towing you want to be a little over 2k. With a manual, keep her in a lower gear in those situations.

You will increase mileage getting a good programmer by ~ 3mpg.

I am far from stock, but via my scangaugeII, I notice that waiting until 2200 rpms or so to shift actually yields the best mileage. The lower rpms (1200-1600) have the lowest mpgs so the less time you spend in that range, the better - at least in my experience. That will vary with tires and diff ratio. If the speed limit is 35, I stay in 3rd and have much better mileage and throttle response than being in 4th at 1100 rpms or so. Similar if the speed limit is 45-55, I will stay in 4th gear the whole time. I never use 5th unless I plan to go 65+.

I totally agree. I yield my best MPG's around 55 MPH in 4th Gear. But there is a point of where 5th is better for certain instances. Like for me heading from home to McCall, ID is a mild grade of about 1.5% grade the whole way for about 10 miles its best to climb that grade in 4th gear and then on the return trip coming down its best to be in 5th gear. But watch the downhill speed still. Even though 65 MPH is speed limit I still see better at 55 MPH through the canyon. Less up and down of the throttle going from corner to corner. Doesn't make sense to race to the corner stomp on the brakes to race back to 65 MPH to stomp on the brakes again at the next corner. It's just best to set the cruise at a speed to can travel the entire trip without changing. Shift points are best if you can wind up enough so when you drop into the next gear your at the bottom of usable torque curve and not excessively low.

Give you a sample. A day to go buy a oil filter from NAPA.

interesting stuff. im running 35s and 3.55 gear. with that set up i am running pretty low rpms in 5th at 55mph. maybe i should try keeping it in fourth. see if i get better mileage
