Synthetic Oil for Towing?

Synthetics handle high heat better than conventional oils, and towing generates more heat than normal driving.

Mobil 1 is a Group 3 synthetic, or it was last I checked, which is barely considered a synthetic. I would look at a good group 4, like Amsoil, and run one year round and based on the year and mileage you would probably be able to do once a year oil changes, something not advised with dino oil.
