Includes about 20 - 25 minutes of idle time, some at elevated RPM due to engine work. Intake manifold plenum gasket was replaced, engine was allowed to idle up to temperature to check for coolant/fuel/vacuum leaks and purge air from cooling system. Acceleration was more aggressive (when engine warm) for the remainder of the tank to get everything seated and burn off any carbon from the blown plenum gasket.

Includes a fairly aggressive, several mile Italian tuneup on the highway.

The last portion of the tank (mostly rural roads) was during and after a severe storm, involved inefficient driving (slow traffic, sudden stops and U-turns, etc).

This tank also included some general vehicle maintenance, including carbon cleaning for the engine. This led to about 10 minutes of extra idle time, and about 5 minutes of idle runtime at higher rpms (2500 or so). This was followed by 5 miles of driving with aggressive acceleration, including 3 WOT runs through 1st gear to clean out carbon.

Includes approx 2 mins warmup at idle before departure most mornings.

The fuel quantity was extrapolated from the mileage displayed on the built-in computer (12mpg) (known to be inaccurate, typically reads 0.5 - 1mpg low). I filled up at a different gas station, where the pump presumably filled the tank further than normal (or otherwise gave an inaccurate reading of gallons), leading to an artificially low mileage calculation (11mpg). Actual gallons pumped were 17.2 (I made it almost 60 miles before the gauge started to move from pegged full).

Due to this inaccuracy, the next tank will be extrapolated the same way, as it would read artificially high otherwise.
