Not 30 minutes ago: 436 miles by the trip-o-meter, 19.1 gallons on the pump. 22.8 mpg, a typical spring result. I'll get another 1mpg by summer.sure you do. I forgot you got the only diesel wrangler produced so far. You are very lucky.
It's not luck. I don't have the less efficient Rubi rear end, I have a manual, and I keep the rpms low. Others (not many) on this forum also report this efficiency.
