I thought something sounded fishy when you said you had a 3.6l and you said owner's manual said 91 was required.
This pic is from the 2013 JGC Owner's Manual and it clearly says 87 and also says anything more helps not. Anything over 87 octane into your tank is 100% wasted money.
Just thought you should know so you can save your money.
Looks like Chicago_Style and I were posting same time.
