I've used my OD for extra gears. I think "1, 2, 2a, 3, 3a, 4, and 4a.
I hardly ever use 2a, and 3a, except when I need a few more RPMs,
like when autocrossing. I just switch it on and off and rarely use
the clutch... `Probably not the best thing to do for and OD, but it's
worked ok for about 10 years, now.

That's not a leak... My car's just marking its territory...
