I think left handed sky hook is something Kareem Abdul Jabbar invented, I have heard the expression left handed blue sky hooks though.

Re: Premium fuel

I really depends on where you live too. I live in Colorado, where I can get away with putting 85 in my Hemi. Some people say I am crazy, but I have had no problems and I still get "great" gas mileage.

You are crazy. No way in hell I would put that junk in my HEMI!

Re: Premium fuel

Polka-dotted paint & left handed monkey wrench.

I just run the cheapest gas I can find. Also keep cars for decades.

Johnnyb_m is on a distinguished road
I have the same dilemma as the OP. Costco doesn't sell 89, and 91 at Costco is less expensive than 89 at the other dealers.

There is a noticeable difference between 87 and higher octane (at least with the winter formulas and in my '11). I've been alternating by tank, but can clearly see and feel the difference in performance and mpg.

So, to reiterate the OP, assuming I'm not throwing money down the drain because 91 at Costco is less than 89 elsewhere, what's the risk to the engine? I'm assuming the warranties (both original and Chrysler extended) would fully apply with higher octane use.

Re: Premium fuel

Nothing really but could save even more with half and half - it is the same way gas stations generate mid ranges.

Be interesting to find out if it runs same/better on 91 or if the MPG goes down because the advance maps do not allow enough advance.

Is really a matter of how well the PCM is programmed.
