In Europe we use a different octane rating than what is used in the US.
The standard fuel here is 95 octane, which AFAIK equals 91 octane in US system. It is an E10 blend.
What octane fuel were the 94-95 5.0s designed to run on? If lower than 91 and I use 91 fuel, what can I do to use the benefit of higher octane? Advance the ignition a little? Any drawbacks? Is it worth it?
