Ahhhh Spinner, let him enjoy that new car glow for a few minutes at least.

Sure the trip mpg is never going to exactly what the calculated it but I am pretty sure in the HCH-IIs they redid the programming to err more on the low side. That way owners are usually pleasantly surprised instead of disappointed when they actually fill up. My HCH-I is almost always the other way around, although over the long run the average difference on my calculated vs trip mpg has been less than .2 mpg higher than actual.
Mattiesettlement, congrats on your new car. If that tank calculates out anywhere near what you are seeing it is a great first tank. Especially with break-in oil, new tires, and new driver. Enjoy it!
