Thread: Ford eco boost and boats

Here is some info for you to consider. The horsepower for the eco-boost is 365 at 5000 rpm the 5.0 is 360 at 5500 rpm. HOWEVER directly from the owners manual for the eco-boost is the following;"Your vehicle is designed to run on regular fuel with an octane rating of 87 or higher. For best overall performance, premium fuel with an octane rating of 91 or higher is recommended. The performance gained by using premium fuel will be most noticeable in hot weather or in severe duty applications such as towing a trailer". I own a 2010 F-150 with a 5.4. I average 15.0 while towing my boat (19 ft Lowe with a 90 Merc) and 19+ not towing on the hiway. Had I waited a year and bought a 2011, I would have bought the 5.0. Engine has been around forever, VERY proven, AND you don't have to spend the extra $$$$$ on premium fuel. It is, however, your money. In addition, the 5.0 towing capacity is 10,000 and the eco-boost is 11,000.
