Wonder what’s more inefficient, a little extra wear and tear, and gas for low gear revving, or letting it warm up for 10 minutes.
Iirc, most car manufacturers don’t recommend letting it warm up on idle. Most say to take of at a moderate speed to warm the engine up “properly”.
I know that driving a car will get it up to operating temperature faster, but whether it's more efficient to let it idle for 10 minutes or to drive in a lower gear could be a toss-up.
This is why we need the MythBusters to get federal funding so they test these things.
