The owners manual should tell you, most likely 87. Putting in a higher octane will not get you much except less money in your wallet.

The above is correct. Buy out west 87 octane is premium. But Ford says to stick with 87 so you'll be pumping premium rather than regular. You need to pay attention to the labels on the pump when at higher elevations.

Above "X 2."

A higher grade of petrol got us worse mileage.

Higher octane only benefits higher compression engines. In the V10 it will usually result in fewer MPG unless the Premium grade is Ethanol Free. To many the Ethanol content will be a bigger concern than the octane.

In some locations, 87 octane is not available. If you visit such a location, use 88 octane.
