Bad gas mileage
I am experiencing the same problem too. On my 09 Lancer ES with 111,500 miles, I changed the oil & oil filter. Also cleaned my MAF sensor & cleaned the k&n typhoon air filter the same time as I did my oil change. Before doing so, I was averaging 420-460 MPG and afterwards, I am only getting 390! Which is a huge drop. I don’t know if anyone else is having the same problems. But I am thinking of putting in some sea foam, readjusting the air filter in case of leaks, and rebooting the car ECU by unplugging the battery for a bit. I’m currently running Gumout solution through my gas tank and still no progress in increasing my MPG. Will update soon.
