I have a 2011 35i and when you fill up your tank, the car tells you how many miles you have to drive until empty. I remember in the past, it would go up to the low 400's, but now the max I get on the display is ~360 miles after I put in a full tank. In reality, I never get near those numbers, but I wonder why it appears like I'm getting less mileage per tank over time. Has anyone else noticed this in their car? Is it simply a matter of needing to do an oil change?
