    Heck yes, the eight speed makes all the difference.

    A newer Chrysler 300 with the 5.7 HEMI and 8-speed automatic is faster than my 2007 Chrysler 300 SRT8 with the 6.1L HEMI and 5-speed auto.

    The engine that does so well everywhere else has caused several Gladiator buybacks. The engine idles rough and a P0300 code is either set or pending, and disabled start/stop. And those who have had engine work, it’s the 2-4-6 bank. Revised flashes haven’t helped, it seems.

    I experienced the rough idle early on, but never had a CEL, and it’s since idled much better. I’m gonna say mine way have been bad gas.

    It's got to be the coding, then... or an issue with the tooling or machinery that produces those heads, if they're different from ordinary JL heads.

    The original issue seemed to be a combination of design, vehicle use (maybe weight?), and, yes, the gasoline used. FCA only tested one brand of fuel.

    I love the Pentastar in our 2012 Grand Caravan. It was one of the biggest selling points when we bought it to replace our 2002 Grand Caravan. It continuously impresses with gas mileage on road trips, usually in the 28-30 mpg range. Even our trip last week wasn't bad. Packed with camping gear from the second row back, two teens sitting in the second row, and three kayaks strapped to the roof. We still averaged 22 mpg.

    Pentestar is much more durable than the 300s that its in. The trans is scary. Bought it used 2 years ago. How do I find out if it was in a flood? I went over the car top to bottom and paid just a bit short of a 2018 300 Base car. Wish I went for the few extra dollars. Fuel economy is tops till you hit Jersey Traffic, then its 15. Not the car to take to the grocery store.
