Eddie Sessum Report post Posted August 11, 2013 I got a brand new MKZ hybrid with 200miles. I filled it up till it clicked plus another half gallon just now and its telling me 348miles on a full tank. Just doing the tank size times the current average it says next to the DTE is 33.6mpg it should be alot more. Almost 100miles more. I gave it some time on the first tank and sure enough it didnt change from the first full tank till now. Is this something that takes time to adapt? I dont have the new update on my car yet and will get that sometime next week. But thats just MPG improvements not something that would make the DTE calculation wrong.

jeff_h Report post Posted August 11, 2013 Yes I believe it takes time for the system to have a solid past history in order to make a more accurate estimate... being a new car there is no history, so the system probably calculates pretty conservatively. My car did the same on the first couple tanks. 1 corncobs reacted to this Quote Share this post Link to post Share on other sites
Eddie Sessum Report post Posted August 12, 2013 Alright, atleast I know its not just me. Do you know if the gas engine has a break-in period too that better milage comes out of it? It seems like whenever its on when moving im around 20mpg. Quote Share this post Link to post Share on other sites
