if you are planning to do your own maintenance, do yourself a favor and get a service manual. all recommended service, frequency and instruction is in the service manual. it is MUCH more involved than oil changes!
the engine gets 3 quarts of 20w/50. before installing the new filter, take one of the quarts and fill the filter....it will take a while.....fill it, let it settle and keep filling until full. pour the remainder in the oil bag.
the transmission/primary gets a quart of "sport-trans lube".
