Well, I wasn't able to take my HCH in until today.
They went over all of the systems and they said they all checked out fine.
I filled up today at Chevron and used the highest grade Techron fuel they have.
My mileage went up to 37.8 MPGs
Maybe the better fuel will improve my numbers.
I did just make an 11 mile trip and achieved 48.9 MPGs... Hmmmm
...I also noticed an improvement on being able to keep my FCD running higher...
Maybe the dealer made an adjustment they didn't tell me about...
....Could a bad tank of gas from the dealership been my problem? <_<
