I use 89 always and have calculated both by hand and by using evic numbers. For me that have been within 0.5 mpg.

Re: 2011 Hemi MPG

87 seems to make the HEMI run a little rough when MDS kicks into 4 cylinder mode.

Re: 2011 Hemi MPG

Down the street from me:
regular=2.48
midgrade=2.63

@ 25 gallons we are talking about a difference of like $4 a fill up......I think the hemi's worth that!

Re: 2011 Hemi MPG

I use 87. No noticeable difference in my HEMI, 89 is recommended but 87 is OK as well. No difference in MPG or power and I have tried both.

I am getting about 14 MPG city stop and go, 20 MPG HW. Averaging about 17MPG.

Dont forget the added expense of wanting to kick yourself everytime you want to pass someone on the highway, tow something, or generally have a better time driving and you realize you should have gotten the hemi. I have never heard anyone complain that their vehicle has too much power but a whole lot complain of vehicles being underpowered.

Re: 2011 Hemi MPG

whatevrworks, that is true. Lucky for us, I have a diesel pickup. So the hemi would be great to have but the more I think just not necessary.

I did a 200 mile trip just after getting my new JGC with the Hemi and about 20% of those miles were city driving and I averaged over 19 MPG

I've been using 87 for the last month and I just started to feel this...it's a very noticeable roughness when it kicks into 4 cylinder...

Tried an Italian tuneup to blast out carbon buildup in the cylinders?

I haven't, but driving a bit tomorrow night after rush hour and I'll push it then. Unfortunately, my commute, while on the highway, is pretty short so I don't get the chance to open it up much.

First real road trip will be Thanksgiving weekend and I'll have some fun then!

Re: 2011 Hemi MPG

I think those highway numbers are a stretch. Around town in my 06, I get 14/14.5 and the best highway mileage I have gotten is 19.9 going 60-65 on a long trip. Not much difference from my 02 with the 4.7 HO.
