Most Efficient .5 Ton While Towing

Ford does NOT require or even recommend Premium fuel. My own experience using nothing but the recommended 87 octane for over 100,000 miles, much of it trailer pulling, is that there has not been any engine or drivetrain issues.

This is a direct copy and paste from the owners manual:

For best overall vehicle and engine performance, premium fuel with an octane rating of 91 or higher is recommended. The performance gained by using premium fuel is most noticeable in hot weather as well as other conditions, for example when towing a trailer.
