engine knock
hey people got my 2011 platnium with the 5.0 moter in september,last couple of weeks i have noticed that this engine has been knocking pretty badly,mostly on up hill climbs,slow rolling type hills and several times when i went to gas it. the manual suggests 87 octane but im wondering if there is a another issue going on here any suggestions?

eingine knock
last tank full i ran 93 octane no issues filled up today with 87 knocking is back thought this engine was designed to run on 87 and with all this knocking should i be worried about engine damage. also someone suggested i run the 87 with a bottle of octane booster dont feel too good about doing that
