What gas octane???
Users of the big gassers: Dodge 6.4, GM 6.0, Ford 6.4....... Can the lower octane be used or do you need the higher octanes????? Colorado we have either 85, 87, or I think 91..

Run whatever the manufacturer recommends which is normally regular grade gas unless you have a turbo which will normally recommend Premium to prevent knocking. Running anything higher is just a waist of money, especially if you live where there is no ethanol added.
However, I am a firm believer in running top tier gasoline for the additive packages they use and I always avoid remote desperation gas stations that don't have fresh gas do to lack of business.
