Has anyone exepreinced a decrease in MPG after the "update for the transmission control module" TSB (Recall 0E-12). It seems that I am getting only 12-13 MPG city after my first oil change when the TSB was done. I have an '06 V6 with about 7K miles. I was getting 15-17 around town and 19-20 on the highway prior to service. I haven't been on the highway since service to notice a difference in highway MPG. I checked tire PSi and it's OK. I switch between 87 and super for gas.
I thought MPG normally gets better as the car breaks in.
