Hi,
I've been driving 2020 SEL FWD for 3 months now and I've got problem with extremely low fuel mileage.
The car was bought with damaged exhuast system (the whole system was torn out) and it has been replaced with substitute, not OEM part. Apart from lots of exhaust steam in the morning, the system seems to work fine - no strange noises, no strange smells. So far, I've driven around 1.000 miles and my city best is 15 mpg (usually around 13) and higway best is 22 mpg. I use 95 octane (Europe), drive slow with not rapid accelerations. Official statistics say the it should be 21/28.
Please help me solve the problem! The car is gorgeous but I can't afford keeping it this way.
