I would drain the oil and either watch them put the correct weight oil in or do it yourself.

Could it be the gas station pump is out of calibration?

Also winter fuel blends typically get worse mpg's compared to summer blends. They probably started phasing in the winter blends this month.

Yup, always starts to roll-out mid to late October

When the car was new i would avg 29 mpg after the break-in .. nowadays i'm getting 22-23 mpg.
its really sad .. i did read something about ignition coils going bad which lowered mpg and engine smoothness:

Wanted to share some additional perspective on this:

Cel started coming on more frequently during daily driving, 6000 rpm would activate it.

Gas mileage had dropped to below 23 mpg average

Car would hesitate and sputter (stalled once) as you pulled to a stop and seemed sluggish in general.

Strange fuel smell in the cabin especially with the fan on high. Possibly unburned fuel??

During the couple sessions that I ran with the cel there was a profound change in the traction / stability control. I had turned it off with the 5 second switch but it was really nuts whenever I had high rpm high g load corners. Motor cut and rear brakes grabbed to the extent that I nearly lost it.

With the new coil, all of these street issues are gone and it feels like I am running the E85 tune compared to how the car was running up till now. The power difference is enough to tell the difference. Even the exhaust note standing outside the car at idle sounds different.

It would appear that when a coil gets this bad, there are multiple symptoms present even if the cel is intermittent.

I actually get the ignition coil CEL when im shifting at the 6-7k rpms with 3rd

Don't date girl effecting vehicle dynamic! Problem solve! Or maybe you are just hammering to see her everyday... Then rest my case.
