For those running premium fuel, what are you seeing (MPG increase and overall improvements if any).
I’m seeing the 3.6 is 11.5:1 compression, and more and more forum discussions for other vehicles that run the Pentastar are using premium with good success.
weather and wind have been fairly consistent here in NE Ohio and over the last 6 days I ran through 2 tanks, seeing just over 3 MPG better on highway runs back and forth to the same place helping my father in law move his inventory from a Snap On truck.
was getting 17 to 17.5 MPG andover the last two tanks of premium have been seeing 20.7 to 21.1. Didn’t have any knock issues or anything before this so running performance (if you can call the Wrangler anything performance related) hasn’t changed much.
Just interested in other feedback.
