Took a quick look to get an idea on prices, and discovered that there
is a rather bewildering array of oils on offer. I'm looking to pick
up a couple of gallons of a standard-grade gear oil for my lathe's
gearboxes. At a glance, I figure they take about 2qts each.

This is an old machine, so it was never designed with super-high tech
lubrication in mind, and even if it was, my wallet can't accommodate a
$400 pail of oil!

Anybody have any favorites?
