Winter/summer differences in my car are confounding me. I regularly run Markham to Timmins in a 1.4t Chev Cruze. 6l/100km on my summer drives, 6 samples dead on the same, I fill up when I leave and make the distance on 1 tank.….
My Bolt's GOM is remarkably good as long as I drive the way I usually drive, and don't pull a surprise on it. It varies quite a bit between winter and summer ...
Last winter Feb, outbound was 7.4, return 7.3, needed a fuel stop each way, wrote it off as an anomaly. On Friday my northbound was again 7.4, and again I needed a fuel stop.
I expected cold to be better. Denser air, windows closed and no AC. But no, 20% more gas in the cold.
Only diff is tires, snows vs summers. Got me puzzled.
