High fuel consumption

a nice good evening in the round, I know this topic “What consumes your custom” has already been addressed countless times. The values given here vary also between 7 and 10 L to 100/km. I drive a Torneo Custom Built 2018 / 170 Ps Automatic and my consumption is around 10 L/100km. Also on long distance / highway the consumption is the 10 liters… The friendly thinks it is a cabinet wall / heavy etc… no error deposited, normal. Now we have since few Where In the company, Ford Transit, with 170 Ps, however, switch. The consumption of the cars lies around the 9 liters/100km are fully charged and are certainly not driven sparingly. What I notice now is my car, in position N, without any electric consumer, warmly driven in the current consumption indicator indicates 0.9-1.1l/h. The value never goes lower. Our company cars show values between 0.5-0.6l/an. Is mine constantly in the cleaning phase?
