    First tank: dash says 41.0, actually came out as 42.5.

    Second tank: Dash says 44.1, actually came out as 41.3.

    Both were topped off. Total average is 41.8 since I bought the car and fixed the HG.

    The second fill may have been a little bit more topped off. Either way, I am spending about $5/week on gas, so I feel pretty great. (Coming from driving a 2003 BMW X5 gas guzzler.)

    I am getting a set of snow tires later today and taking it on its first highway road trip since I bought it and fixed the head gasket. Looking forward to having a long trip under its belt and seeing the highway mileage.

    What was the miles on it? Have you also cleaned the EGR circuit?

    I am at 263k now, and yes I had it cleaned in the ultrasonic tank until it was sparkly.

    "it" ?
    Which parts did you clean?
    The intake manifold is the important part because it is the part that makes the individual port flow uneven.
