2009 Hyundai Accent GL 4 Cyl 1.6L
MPG has dropped from 32 MPG to about 30 MPG. Why???
I bought the vehicle about 7 months ago with 20,000 miles on it and consistently got 32 MPG and now it has dropped to about 29-30 MPG, only thing I have done is change the oil; tires are new and in good shape. What could caus ethe drop, air filter? Or something else?
Here are some simple suggestions;
