2010 Mercury Milan Hybrid - MPG going down

[texases]

Here’s that discussion:

2010 Ford Fusion Hybrid electrical motor comes on less; mileage dropped

@Fins2l2r_154900 - Do you have any links that discuss this timer issue? I have a 2011 MKZ hybrid, wondering if it applies to it.

My '11 MKZ hybrid dropped a couple of mpgs when I switched tires.
