Gas?

Regular or premium? What's the consensus on 3.6L?

Re: Gas?

Asked and discussed many times - consensus is to do as the manual suggests. 87 for the 3.6 "as using premium in either engine offers no additional benefits" according to the manual.

Re: Gas?

I use 93, but I have a supercharger. 😄 Just use 87 for naturally aspirated.

Re: Gas?

I have a naturally aspirated but may be using 89 and 91/93 alternating. My engine pings on 87...and it's a 2014.

Re: Gas?

It shouldn't, it's designed for 87. Take it to the dealer.

Re: Gas?

i have taken it to the dealer. Was told by Svc Mgr that it's "normal" for the detonation/pining to occur sometime.

I plan to push through the 93 octane this time and hope it cleans it out to go back to either 87 or 89.

Re: Gas?

That service manager is full of Sh!t. As long as you're buying decent quality gas, there should be no detonation on 87 octane.

Re: Gas?

Use the manual folks. There shouldn't be any debate unless you have heavily modified your Powertrain. If the dealership told you that pinging is normal than they are insane. Good luck with that.

Greetings,

Correct.

I have been using 87 for my 2011 since February of that year., never a problem.
Try filling up at a different gas station next time. If still happens, then go to a different service dealer. You could have shot plugs which very very rarely does happen.

And if you do not have a tuner running or a turbo kit or a supercharger, 87 is all you need. Just as the manual and other threads about the 3.6 gas has been discussed.


Best for now.

Re: Gas?

OP, why would you even consider using premium fuel which the 3.6l was not designed to run on? Use the recommended regular 87 octane. There is no benefit whatsoever and is only going to cost you more money.
