Another MPG thread - 2500 mile mark - V6 TH
I know we beat this dead horse enough, but I've just realized a definite improvement. My last fill up was after I passed the 2,500 mile mark. It was over 1.5 mpg better than what I've seen prior. I had been doing good to see an actual 19 mpg. Many tanks were high 18.x mpg despite how much highway miles were in my mixed cycle. Just a few were around 19.5. Then last night's fill up netted 20.9 mpg. Same right foot, same daily routine, but it's clearly improved. I was curious if anyone else has seen an improvement that's hard to explain. I wonder if the ECM changed at the 2500 mile mark. Like some kind of break-in programming ending.
The weather was warmer for many days, but our entire winter has been mild. This morning, my avg mpg by the time I got to work was 21.8 mpg indicated. I always fill up at night and go straight home about two miles away, then drive to work the next morning. Normally, it would indicate 19.x after the same two drives immediately after a fill up.
I also noticed higher current mpg values at various points during my highway portion this morning. I suspect this tank will mimic the last one. If it will now hover between 20-21 mpg rather than 18-19, my only disappointment in the vehicle will be erased. The first several tanks barely able to do 1 mpg better than the city rating was a major letdown.
Also worth noting, what has remained consistent over the last several fill ups is my EVIC avg mpg is 0.8 to 0.9 higher than actual. It was nice to see it remain consistent even with the improved gas mileage.
