This is all very useful unless you drive a Mini or one of its
variants, wherein the gearbox is in effect the sump for the engine
and they therefore share the same oil. (This of course, is the same
design as the Lamborghini Miura, showing the foresight of Alec
Issigonis) It is highly recommended to use a REAL GOOD oil, err on
the side of greater viscosity and change it often.
I also recommend the extended magnetic pickup available from the
suppliers, as well as an additional magnetic pickup in the main oil
pump pickup circuit (a friend and I sell these..along with billet alum
shift knobs). I change the oil (mobil 1 in my case) every race weekend...
If it wasn't a product of leyland, I might worry about all the
pieces I find on the end of the magnetic pickup...but, so long as the pieces
are not too big, I don't worry about it.
