Letting your car idle for 10 minutes or more is a waste of fuel.
Your engine does not need to be fully warmed up to drive.
It only needs, at the most, a full minute.
Most of us drive our cars after idling for 30 seconds.
The shifting improvement can be felt just by placing the transaxle in neutral,
engage the clutch, and then tapping the accelerator a few times
to spin the gears in the transaxle and distribute the oil within the transaxle.
This will insure that all internal parts are lubricated prior to your lauching...
This has been documented very well within this forum.
