i would go to my local parts house and buy a service manual for the particular car you have and go exactly by their directions. I would then replace your oil with a good synthetic oil such as AMSOIL 7500 SERIES oil and their special filter. this way you won't have to change oil but every 7500 miles and stop sinking money into do it yourself or Walmart deals.
