  1. Diesel Milage down YOY from 2020 to 2021?

    There's already a thread on this.
  2. 2021 Rubicon EcoDiesel EPA rated MPG drops (per window sticker)

    Well maybe you guys should buy lotto tickets. :D The average person isn't seeing anywhere near those numbers, and neither am I. Which takes us back to the original post...that Jeep is adjusting the window sticker MPG downward to be more accurate, and they probably need to go down even more.
  3. 2021 Rubicon EcoDiesel EPA rated MPG drops (per window sticker)

    Unfortunately none of those reports are trustworthy, which is why we have to turn to to get the truth because those hand calculations take the guesswork out. And what we're seeing so far after nearly 40,000 miles of combined real-world data is a MPG figure around 20.7 MPG. This...
  4. 2021 Rubicon EcoDiesel EPA rated MPG drops (per window sticker)

    It's probably a more accurate number. Perhaps they retested it, or tested it in a more real-world trim level? Perhaps they saw how Ford is being repeatedly sued for fudging the numbers on their EcoBust family of engines? In any case, the lower numbers are more accurate based upon what I'm...
  5. Gearing and transfer case on diesel with larger tires

    I guess it totally depends on what you're looking for. Do you want to stay in 8th gear constantly on the highway? Then gear the hell out of it. Do you want maximum fuel efficiency? Stay 3.73 (or regear to 3.55 which would be even better). It seems that there are different needs for...
  6. Tracking Jeep JLUR Diesel Issues

    Starting to become common, and obvious that VM had a bad batch of timing covers. What is your build date? My repair took two weeks. The technician had a hard time removing one of the injectors to make access to the valve cover so he could get the timing cover off.
  7. List of Chrysler MS-12991 Engine Oil for the 3.0 EcoDiesel Jeep Wrangler

    Which is precisely why I do my own service. The ONLY time my Jeeps/Rams go to the dealer is for warranty REPAIRS. It saves money, and I know it's done right.
  8. V8 Wrangler Rubicon 392 Concept drive review by MotorTrend

    They saw 9.4 MPG because their foot was stuck into the accelerator pedal 85% of the time. The Ram 2500 sees 13 to 14 average in the real world. The Wrangler with same powertrain should be good for 15+ if the driver can deny the temptation to let those American horses run.
  9. Diesel Resale Value

    Well you should buy a lotto ticket then. The Rams are hard to even give away. People see "EcoDiesel" and run. And, most dealers got to the point where they wouldn't even order new ones for inventory any longer. So, this new engine will need to prove itself.
  10. I think I purchased too much Jeep?

    The depreciation hit you're going to take is nothing compared to how much more the EcoDiesel is going to cost you to live with as years go by. So, if $$ is no object anyhow then go for it.
  11. Anyone have a High Altitude With the 3.0D?

    I agree. I'm a fan of Billet Silver. I'm a fan of black wheels. I'm a fan of Jeeps. I'm a fan of diesel engines. But there is something about the combo of all of those things that does not appeal to me. The one pictured above reminds me more of an ultra-expensive G-wagen or something. I...
  12. Diesel Resale Value

    Resale will be interesting to watch on these. On one hand, the Gen 2 engines were such garbage that you can't hardly give those away. On the other hand, this is a new engine design and it's the first use in a Wrangler. So it'll be interesting to see if they hold value over time or not.
  13. List of Chrysler MS-12991 Engine Oil for the 3.0 EcoDiesel Jeep Wrangler

    So here's the deal: Gen 2 EcoDiesel spec'd a 5W30 oil. After many engine failures, they upgraded that spec to a 5W40. Engineering reasons for this are debatable but most people feel it was to give better cushioning to the main bearings since a diesel really is hard on pistons and bearings...
  14. Just threw a CEL P00AF code at 7100 miles. Update: This is a major issue!!!

    The Ram has a MUCH larger engine bay, and even still you can just barely see the turbo. I've done a lot of work including engine replacements, installing headers on Camaros where there is NO space to work, etc. When I look at what it would take to replace a turbo on this Gen 3 EcoDiesel, I...
  15. 2021 Diesel gearing changed to 4.10?

    More specifically: All these manufacturers never had shit for brains in the past because they did 3.55 or numerically lower with diesel engines ALWAYS. It's only recently that they've started growing shit for brains by drastically over-gearing the diesel, especially in light of the fact that...
  16. DEF Usage

    I believe that idling increases usage, and cold weather does as well. That may be why most of us saw decreasing DEF usage as we got into summer. When I got mine it was February and the DEF needle dropped fast. Now, not so much.
  17. DEF Usage

    I have never seen DEF that wasn't labeled as certified. I'd be willing to bet that the $7 Walmart brand comes off the same line as the $13 PEAK brand. Y'all are overthinking this. It's a urea/water mix. Not a lot to go wrong there.
  18. 2021 Diesel gearing changed to 4.10?

    Sure, we can agree to disagree. The diesel has half the power band of the gas engine and makes nearly double the torque at nearly half the RPM. Completely different ballgame. You must throw every bit of conventional wisdom regarding axle ratios out the window. Nothing above 3.55 should even...
  19. First Diesel Oil Change

    Oh, and do not use a Gen 2 filter on the Gen 3 engine. Yes, they're cheap and yes they're easy to find, but don't do it.
  20. 2021 Diesel gearing changed to 4.10?

    That would be incredibly dumb. They should go 3.21s. There is ZERO reason to do a deep gear ratio with a vehicle that only has a small power band and makes all its torque at 1,600 RPM, doubly so when it's mated to a great 8-speed trans. This thing doesn't tow or haul any real weight, so...
