Please forgive such a basic question, but it is time for me to get my hands
dirty for the FIRST TIME on my van ...

You may remember my "oil burning" problem from last weekend.  Some of the
replies I received, and most of mechanics I spoke to advised me to try
20W50 in the engine to see if that didn't clear up the problem.

Having always taken my vehicles to a quick-lube type of shop, and realizing
that I might be shelling out a lot of money if I want to try changing my
oil frequently to clear up this problem ... I've decided to try changing
the oil MYSELF!

Except, I have no idea where the oil drain plug is.  Is it the one that
looks like a slotted screw?

Thanks,
