I have the 6.2 (see sig) and only run 91 when towing. I run 89 all other times which saves 20 cents /gal. I've never had any pinging or other ill effects. This engine/trans combination gets great mileage and is so much nicer to drive than the 2500 I traded. My 2500 got 13mpg combined and the 6.2 gets 17mpg combined. Have you test driven one yet?
