This is the warmest it'll get after running down the highway for awhile. Usually around town it runs even colder. I suspected a stuck-open thermostat so I replaced both of them and that didn't fix it. I'm used to all my other vehicles which always run a hair under the middle marker on the gauge. Any ideas of is this the temp these new Sebrings run at? I'm just worried about taking a hit in gas mileage if it isn't heating up properly.

 

It's fine.
