From new, the gear oil should be dropped after 2K miles and replaced with
Mobil 1 fully synthetic gear oil. Replace every 2nd service, that is approx
every 2 years in most cars. After approx 25k miles add Slick 50 gearbox
treatment at each g/box oil change. The transmission will remain like new
for nearly all the life of the car.

This is, of course, a *huge* pile of crap.
