18mpg on a stock 5.0

RE: 18mpg on a stock 5.0
Could possibly, maybe, be the switch to gas with ethanol rather than mbte. Each time they come up with a new gas formula it ends up killing performance and we only end up burning more gas. Any changes in traffic or anything? I've lost about 3 mpg just from stopping at 5 or so extra lights.
