poor gas milage

accountname19 · 05-16-2022, 09:39 PM

Hello, so I have a 2009 335xi and for some reason i consume 22l/100km I have no idea why, and I have index 12 injectors. Could someone maybe point me into the right direction to troubleshoot the issue? Unless this gas mileage is normal? Thanks in advance

Before you drive yourself crazy, do a controlled highway test at 100K/hour, say for 50 KM.

And then report back with an mpg, which is a good test of your math conversion skills!

Just stay away from the Finnish border or the Baltic sea!
