Fuel mileage drop - 2014 CRV - 71000 mi.

[Sceptor]

Hey guys.  I have had a drop in my mileage over a 3 month period from 35 mpg to 21 mpg and it's still dropping. I'm the only driver and I use drive for mostly short distances. I spoke with a service advisor today and he said nothing could be done (?)   Any thoughts?

I had this issue with a VW Jetta many years ago.  Problem was a failed temp sensor in coolant.  Didn’t detect increased coolant temp and therefore car was running “rich” like choke being pulled out on cars before computerized fuel delivery became the norm.
