Hi All!
I have noticed in my Seat Leon 2016 1.4 TSI ACT 150hp (CZEA engine) quite some difference in fuel consumption between cold and warm/hot weather on the same trajectory/tires/tank/driving style. The diff can be sometimes more than 1L/100km.
In addition to that I noticed that the car feels faster. I tried to look online/AI but couldn’t find a convincing answer to my question.
Do you have the same thing ? Does anyone have an explanation ?
Edit: Forgot to mention, the car is tuned to stage 1 and filled up with E5 (98)
