Re: Stick yer clutch in!
I'm always puzzled by this advice, since the load on the crank thrust bearing(s) (which also the oil has drained off with standing) is going to offset the reduced transmission friction. The cranks thrusts only wear while the clutch is depressed, so it's a very good idea to put it out of gear when waiting in traffic/at junctions anyway. Hydrodynamics also usually ensure that the force seperating the metal is a function of rubbing speed, so at cranking the thrusts have least protection.
I don't do it, and I don't leave it in gear so clearly I'm 'wrong' - I did once have handbrake problems which led to car introducing itself to tree unmanned.
Doesn't say that in the manual
