Hopefully by changing the filter my mpg will go back up. I'm having a hard time getting 21mpg. Normally I'm at 24-25 this time of the year. It might have something to do with that new software update I got from the dealer few months back.
They may not have updated the site to reflect what the new models manuals say. Looking at that filter would be enough fir me to shorten my interval. My manual says 30k for air filters-looking at the aor filter after 30k miles was enough for me to start doing it every 10k
