Short Shifting
I have a country road 30 minute commute one way to work, 55MPH top posted speed limit. Doesn't pay to go blasting through a small town.
Lately I have been short shifting, hit about 2000, shift, pick it up at about 1500 and repeat. Engine is rarely seeing 2500 on the daily commute.
I do not have any data that this helps.
One time I was listening to Sirrus and on the Trucking channel (147?) they had a fleet manager and were talking mechanical and maintainance issues with OTR drivers, question repeatedly came up asking about mileage and his first question to the drivers was always about shift points.
