You should be using 87 octane...as per your manual. You'll get no benefit from 93 except less money in your account. E85 is optional since the V6 is a "flex fuel" vehicle, but you'll get far less fuel economy and little or no financial benefit.

Re: 2015-2016 High Altitude Owners Thread

Unless your engine is setup to utilize higher octane and automatically adjusts timing, etc for higher compression, there is no benefit to paying the premium for 93 over regular 87. Ethanol will save the environment but cost you more per mile to accomplish that as E85 has less energy per gallon than regular gas. E10 (90% gas, 10%ethanol) is what's mostly available on the east coast, and other places I've traveled to. The only ones that benefit from ethanol sales are the corn farmers. The cost to produce ethanol and the cost per mile still make it a loser for everyone else.

Good to know. I will fill up with 87 next time to compare the MPG

Yeah don't use 93, the correct fuel for your vehicle is regular 87 octane. If you like throwing money down the toilet might as well send it my way

---------- Post added at 03:51 PM ---------- Previous post was at 03:43 PM ----------

To get back to my all of a sudden shifting issues. I have been paying attention to it as much as possible and its definitely a cold start thing, cold being relative considering its 90 degrees outside. Cold as in first start of the day, or atleast been sitting a while. Its only the 2-3 shift and like I said before it seems to do that shift early and much firmer. So much so that the passenger I went to lunch with today at work said "whoa" lol. He isn't completely foreign to this though as he has a newer Chrysler 200 with the 9spd which also does goofy things lol.

I have noticed that the weird 2-3 shift completely goes to normal after the tranny temp gets to approx 130 degrees. After that point it shifts 100% normal and smooth. Last night I let the battery sit unplugged for a good hour just to see if that reset anything or changed the shifting but it did not. Any recommendations guys? And for those 8spd V6 that have experienced issues is it pretty much exactly the same issue I am experiencing? For those that do/did have the issue did any software updates fix the problem or is there a chance I now have a permanent f'ed up 2-3 shift when cold? Any TSBs pertaining to this exact issue?

LOL sounds good

Also, I'm trying to get MGP or Jeep hrake covers and I need to know if I'm using one piston BRY or two piston BR6 caliper. Can't see the piston on my actual brakes. Is there any VIN decoded that gives you all the information codes we have?

Wow! Anton Urchin, young actor from the newer Star Trek movies, was crushed to death supposedly because of the GC shifter.

Re: 2015-2016 High Altitude Owners Thread

its weird...just because I've had it happen to me like 7 times in the 4 months I've owned this thing...never have I experienced this type of thing,i also have a 2015 merc gla with the super funky shifter but that has a fail safe that automatically puts it in park if you open the door....I'm pretty in tune to stuff like this and I will tell you that my 2015 shifter is not 100%. I park on an incline so I'm also pretty sensitive to stuff like this too...wonder what they will do....

Mine at cold start only shifts funny going 1-2. After that, or letting it idle for 5 minutes it shifts fine.

Re: 2015-2016 High Altitude Owners Thread

Hey High Altitude Owners! I am new to the forum, first post. Proud owner of 2016 White JGC HA 5.7L Hemi. Loving the first month!

After reading a fair amount on here and knowing exhaust would be my first mod, I have decided to go with Corsa twin tips exhaust. 2 questions...

1. Does anyone have a picture of this exhaust on their HA right now?

2. Can you use the stock tips with this exhaust if you wanted to?

Re: 2015-2016 High Altitude Owners Thread

Welcome to the board, I'm sure if you go to a competent exhaust place they would be able to modify the corsa to use the OEM HA tips
