some question for overland owners
 
I am just enjoying my first day with the new overland, but I have a few questions I hope others can answer.

1. I did not have an optional radio so I was expecting the 430N to be in it, but the radio I have is a little different and it has RER on it. I think this is the 730n but I was not changed anything on window sticker. Can someone clear this up?

2. With QL I read you have to disable this when lifting it off the ground. How do you disable it and would this be required when getting an oil change?

3. Is 89 octane required for the Hemi?

Thanks for any answers to these.

I am really liking this thing so far no problems to report.

Question back... Did you get the Overland or the Overland Summit?

As for the 89, The books all say to use 89 but there has been a few discussions about it in some of the other posts. It looks to be a mixed bag of choices but for now (one week owner for me) I am going to stick to the 89.

I got the overland blackberry with black interior. One other question I had was tire pressure it says 36 in the door, but mine came set at 40 have others stayed at 40 or reduced to 36?

^^^ I understand they over inflate the tires for shipping....possibly to prevent flat spots. I adjusted mine to 37.....just 1 lb over for now. Rides a bit better than the 40+ lbs. I think dealer prep is supposed to adjust air in tires but they don't always.

I'm sticking to 89 in my V8 Hemi. I used 87 forever in my 2005 Hemi but had recently switched to 89 and there was a noticeable improvement in power and responsiveness. My dealer said to not use 91 since it burns hotter...not sure if that is true but sticking to 89.

My $.02...

Q2- Hold both Up and Down buttons at the same time for a second or two. They will flash to indicate the QL has been disabled.

Q3 - Stick to the recommended 89. I would only use 87 if for some reason the 89 wasn't available. The 91 won't hurt anything but your wallet.

Q4 - My tires were also overinflated. Would definitely lower them to 36. Check pressures while the tires are cold.

Mine are at 40 too... I will have to deflate them tomorrow. Today I discovered the cargo net :) I only have 159 miles so far but I am really enjoying my new summit too :D

5th Jeep, 2nd Hemi. Always pumped regular unleaded, with no issues regarding performance. IMO, there is not a noticeable performance difference between 87 and 89 octane. Believe me, when I am on the open highway, I go WOT. I have used both octane level's. No noticeable difference, except price/gal. at the pump. The engine will not suffer drinkining 87 octane.

RER is a 730N Radio. Now relaced with the 730N RHR. Sounds like you GC was built in Nov or Dec of last year. As mine was it has the 730N (a $305 upgrade) with which is not listed on the sticker.

1) RER is the 730N. So is the RHR.

2) You only need do this when the wheels will be hanging in the air, like when it is on a lift. Hold up and down buttons for about 5 seconds, there will be a message in the EVIC. It will be re-enabled at key cycle (when you start it again) or when you drive over 15mph.

3) Yes. 89 octane (mid-grade) for the Hemi. You can run it fine on 87 octane, but it will adjust timing to prevent knock and you'll lose some power. If you bought the Hemi for the power, feel it mid-grade.

It doesn't really matter what you did in the past, the 2011 5.7L Hemi in the WK2 is configured to run 89 octane as the preferred fuel. Sure, you can run 87 but I fail to understand why people insist on rejecting the recommendation from the manufacturer simply because they think they know better......

Oh, and 91+ octane fuel DOES NOT burn hotter, that's a typical response from a mechanic who has no real training in this area of expertise.

Octane rating does not relate to the energy content of the fuel (see heating value). It is only a measure of the fuel's tendency to burn in a controlled manner, rather than exploding in an uncontrolled manner.
