Today I drove my usual 4.1km to work. The temperature outside was -19 degrees Celsius.
When I started my car the distance to empty was 401km. When I got to work the distance to empty was 380km! (When I fill up to max, distance to empty is 540km)
Now I always found the distance to empty was a pretty accurate number as it seemed to be tailored for city driving. For example, when I drive 120km (90% highway) to visit family, the distance to empty goes down at max 80km.
Is there any tips you guys have to improve winter fuel economy?
