my average since I bought the truck is up or down of 10L/100, but not sure how far back the evic stores the data for the calc. My hand calc over the 9 fillups is 26.5 Cdn mi/gal. Yesterday I took it to our offsite my avg was 8.0L/.100, but that is at 80km/ hour over a 100km trip. I mostly drive city 60% and the other hwy but pulling a trailer, so I'm happy with that.
