Chevrolet Malibu Maxx Real World MPG
A month ago, I lost my dashboard power, HVAC controls, and radio. It wasn't a fuse, but a bad 3controller unit. The controller had to get replaced... under warranty.
At the same time, gas prices surged from $2.65/gal to $3.05/gal and I also understand that we are swtiching over to E-10 fuel (10% Ethanol).
Well, since I got my car out of the shop, my MPG has dropped greatly from 27 MPG to 22 MPG.
What happened? The repair, E-10 switchover, or both?
