My 1986 900T burns lots of oil on overrun, and typically goes from max to min in around 6k miles. Did you check the oil under the same engine conditions? If, for instance, if you check the oil just after engine shut down, you'll get an artificially low reading, because much of the oil will still be in the engine top half. I usually check mine about 1-2 hrs after shutting down, which gives a consistent reading. As for the oil changing procedure, it's pretty simple. Find your drain plug (quite obvious, on the oil pan, hex head). Warm up engine, shut down, and leave sitting for at least 30 mins. Place large tray under drain plug Remove drain plug. Careful, the oil is hot, and rubber gloves are recommended. Let all the oil drain out, until no more comes out. Replace plug, and torque with a torque wrench (see manual for setting). Remove oil filter (towards the rear of the engine bay on my 1987 9000, not sure about your 1990 9000). Wipe oil filter mating surface with clean rag. Smear a small amount of clean oil on new filter gasket. Spin on new filter and hand tighten. Fill up with specified amount of oil. Run engine. Shut off, let it sit, and check oil. Top up if necessary. If you don't have a Haynes manual, get one., or Grunff
