kits73,
I use PP in the winter and PYB the rest of the year but I put 20,000 miles a year on my car
My wife's car I just use PYB she only puts 12,000-15,000 miles a year

If you guys are not 100% sure what weight oil to use you can always go to Mobil oil or Pennzoil web site they both have oil selectors for cars and trucks.
