2017 Fuel Economy Update - 2016 Mini Cooper S Electric Blue Metallic (Post #13)

Hello, everyone!

Time again for the latest fuel trends.  As usual, fuel costs are the strongest variable coupled with my trip computer peaks and valleys.  The peaks represent the times I travel the highways for road trips verse the day-to-day typical drive to and from work.  When the mini is running the highway, it excels at gas mileage.  Between the occasional fuel rewards I cash in, and the fluctuating market, the fuel line will always be slightly erratic.  The cost per mile is almost a flat line.  I do not expect that to trend one way or the other from what you see already.  It's only going to change on the last set of graphs whenever the next maintenance event is out of my pocket.  Noting really to call out beyond that.

That said, I'm starting to see more entries where the Actual MPG and the Computers MPG differ by wider margins.  I can tell you that my driving habits have changed very little so the variable is not in my driving.  From day one until present, the average difference has grown to almost two MPG.  Now that may not seem like a lot, but I question how the computer is programmed verse the basic math to trend that much of a difference.  The mileage is not the variable as the computer trip computer matches, so I expect it's in the fuel tank calculation from what the sensors read to what I actually put in.  But of the 60 recorded entries thus far, 23 are more than two MPG off the mark, and five are more than 3 MPG off the mark.  The largest delta was almost 4 MPG back in April.  And all the delta's in MPG are higher from the computers perspective.  So if you are using just the computers calculation, it's going to make it look better than it really is for your MPG.  Just a call-out more than a concern right now.

The third graph from the top clearly shows whenever I have a road trip verse the day-to-day driving as well.  Again, the MPG overall is great, but keep the mini on the highway for most of its driving and you easily jump up from an average of 35 MPG to almost 40 MPG.  Big difference!

Let me know your thoughts.  Appreciate all the comments and questions I've been getting along the way.

Until the next update...Motor On!!!
