Most vehicles might be on side of drivers door or has around the front of the radiator or under the hood a sticker that well display oil filter type how much oil what type etc.now look in your owners manual or go on line look up make model of your vehicle oil specifications it should give all the info you need very important the wright oil filter pcv valve all v-8 are 5 quarts.6cyl can be 4 to 5 quarts.if engine is not using oil running normal than do this drain old oil replace pcv valve replace oil filter pour in 4 quarts turn engine on wait about three min turn engine off wait let oil drain back down to oil pan check oil if dip stick reads normal or maybe one third low add one third and save your fifth can.incase you need to add later.every three months oil change is recommended in any vehicle every six months check transmision fluid,every six months check differential fluid especially if you own a 4 wheel drive. that is your front and rear axles.all ways remember oil filter itself well hold about one third to a quart of oil depends on the size of the oil filter.thats why your dip stick my read a little low after checking when your oil change is done.
