Damaged Purge Valve ??

[NH-RCSB]

I have a new (8k miles) 2025, RCSB, 4x4. I consistently get 19-21 mpg. After filling up the tank last week my average mpg in now 14 - 15.
Is it possible that I damaged the evap purge valve by topping off the tank ??

If it got overfilled, yes it is possible but usualy would get a DTC. May also just be bad gas, or winter formulation causing the drop in mpg.

No,.. not remote starting. Like the previous comment mentioned. Possibly the winter blend fuel has hit NH ??
