[s-cars] Oil Plug removal -> Dynamite required

[Kirby Smith]

IIRC, when I tried to remove mine the first time, once I gave up on the
breaker bar attack I pulled out a 3/4-inch drive air wrench.  This
proved sufficiently persuasive, and had the added merit of minimal
disturbance to the chassis I was under.

If one is going to use the regular plug and not a Fumoto valve, I
recommend NeverSeize or one of its analogues to keep the aluminum from
trying to bond with the steel plug threads.  After this first removal up
to later Fumoto installation, I had no problem removing the plug with
this approach.
