Ask Any Jeeper: These Are the Engines You Can Count On
9. 3.8L V6 (Bonus: Not on this list for a reason)

OK, not every engine was a home run. The 3.8L V6 from the 2007–2011 Wrangler is what you won’t see on this list—and for good reason. Oil burning, weak power, and a wheezy response made it a dud.
Just a friendly reminder: not all Jeep engines deserve praise. But knowing the bad helps you appreciate the good even more.
