My best MPG Tool is the ScanGaugeII that indicates my instant MPG reading, and a lot more valuable readings. I tend to try to keep a constant MPG rate while trying to increase the MPG average. I have seen averaging 23MPG for milles at a time. But city driving with trafic lights just kills the average.
I have a 6 speed and the RPM that I operate my truck make a huge difference in town driving. I seldome shift to overdrive till I am above 50MPH, I use to shift at low RPM thinking I was taking it easy so MPG would be good, Well I do the opposite now, I shift around 2000RPM and it allows the engine work more effciently.
I had a 4 Cylinder Ranger one time and my best milage was witout using the overdrive.
I find that with my programer the efficiency is at higher RPMs then at stock setting. So I get much better milage advantage at higher speed.
While towing I shift at 2200RPM and to OD at 55MPH. If I drive below 55MPH or on hilly highways I get great milage on drive. When towing on level roads the best milage seam to be with the engine at 1750RPM on OD. I get all these max efficiency readings from my ScangaugeII Gauge.
There are now more models of these type of gauges available, I use my scangaugeII so much that with 4 gauges I hardly check my regular dash gauges. I usualy monitor the MPG,Water Temp. Intake Air Temp, Ambiant Temperature. Exhaust Gauge is not shown on the 6.0 so I have a Pyro.
