the specifications section in the owner's manual should tell you what all of the fluid levels shouls be. also, look in the index under oil or engine oil for where to find it. and if you do not have that manual on hand... my 03 XL-7 takes 5.8 quarts. It should be about the same for yours. your dip stick shoudl have two holes on the bottom tip - keep the oil in the middel for a safe measure.
