So my cars done around 3000 miles now, 5 months old and I’m getting 275 miles out of a tank. I’m usually getting around 27mpg on a 30mile run. Highest I’ve seen is 40 on a 250 mile round trip. I drive in comfort to try and help and I’m certainly not ‘lead footed’. My stop/start rarely comes on and when it does I can’t get my head around how it works. I could use the car heavily for 3 days and not see it come on once. I could not use the car for a week and it will put stop start on when I get to my first junction. I thought I had cracked it the other day when I switched the air con off completely (always in a/c eco) as it seemed to work straight away. I did get around to checking my tyre pressure the other day and they were 42psi front 40psi rear so I’ve corrected that. I also don’t drive with my windows open and my boots always empty. I wasn’t expecting great figures just better than my 8 year old 330i I changed it in for, which coincidently also used to do 275 miles a tank. What’s other owners getting to a tank?
