Re: Gas grade for 3.0 duratec
You can use any grade of fuel you want, but keep in mind that using a grade higher than 87 is just wasting your money. The engine was designed for 87. You may notice (as I have) with more modern FI engines that the engine will use more fuel with higher octane gas. Not much more but it is noticeable.
