Hi everyone.  I have a 2021 BMW 116D M Sport F40 and I think it is using too much diesel.  I used to get 47 mpg now it is 41.9 mpg.  Only myself and a small dog are traveling in the car.  Not luggage etc.  I don't speed.  Why is my fuel consumption so low?

Morning Dennis

Have you changed where you fill up? My X5 3.0d was averaging 28/29 around town short journeys then a new filling station opened close to home so I started using it and over a month or two noticed a drop in MPG, same fuel supplier. The only thing that made sense to me was pump calibration? An argument I lost with the station owners by the way so guess where I fill up now

I am assuming here that the car has no faults and is fully serviced

Hi,

 

I just use service stations like Tesco etc, sometimes Sainburies.  The car has full service the last by BMW York

Unless it is the additives that go into all fuels now I am at a loss. You have got me keeping an eye on the fuel gauge now 😂

Have a Peaceful and Restful Christmas

Me too Dave.  All the best for the season and hope we all get cheaper fuel, light shoes, and a lighter right foot!  LOL!
