What grade of gas does your large gas engine require
With the big V-8 and V-10 engines do you have to burn a higher octane than regular unleaded? Back in the days of muscle cars you had to burn premium. Does that apply to big blocks in RVs?

Ford Manual and Winnebago manual says 87 octane in the tank for the Triton V-10. Can anyone explain to me why 85 octane is sold at the higher altitudes? We have a home in Ely, NV where that octane is sold. Always wondered why when manufacturers have called for 87 octane minimum for many years.
