gas mileage
I've had a considerable drop in my gas mileage. I was getting 31-33 mpg on my 2015 TLX and now I'm at 28. I thought I just needed to clean my KN filter but that didn't change anything. The vehicle has about 65000 miles on it. Is there anything else I can be looking at as to why I've had a drop in gas mileage? This is the first car I've kept over 50k so maybe there's a maintenance thing causing it.
