Do I live in a very cold or very hot climate? Is it mountainous? Are there abrupt changes in temperature? Multi-weight oils cover a range of temperatures. The smaller the number before the “W”, the oil will work better in cold climates.

How old is my vehicle? If you have an old vehicle that has been running on one-weight oil for most of your life, it’s likely that a little mud has accumulated, since some single-weight oils do not have detergent in them.
