Hi Bob,

As always, thank you for your update of the nice FAQ.

I would like to comment one thing...
You wrote " In cold weather, an engine block heater can save...".
The block heater saves gas not only in cold weather but also in summer.
It is very good weapon to save gas on ICE warming up in all season, especially for short trips.
People are saying they can't stop using it even in summer, it's like drugs.
