6.4l

  1. 6.4L Towing performance and fuel economy

    6.4L (392 cu in) HEMI V8 Specific Topics
    I recently purchased a 2017 Ram 2500 w/a 6.4L Hemi, automatic, crew cab LB Big Horn edition. I also just purchased a travel trailer in Evans, CO and towed it back to Oregon where we live. We averaged 6.7 MPG on the trip running 55-70mph on I80 heading west. I was refueling every 125/130 miles at...
  2. Decisions, decisions...a crossroads

    First a little background: As I get closer to coming home my wife and I are looking forward to a period in our life where we will actually be able to spend a decent amount of time together. Between deployments and training the longest we have spent together has been 5 months and I have spent...

  4. 6.4 Hemi Vibration/Shudder NOT MDS

    2017 Dodge Ram Forum
    Hello all, looking for a little advice if anyone has any suggestions. I recently purchased a 2017 Ram 2500 tradesman with a 6.4L. Its got a shudder of some sort, simply feels like it has a miss. It does it when towing my RV and the tow/haul is engaged so the MDS is turned off. It does it...
  5. 6.4L Hesitation @ Low Speeds/RPM

    6.4L (392 cu in) HEMI V8 Specific Topics
    My truck has less than 2000 miles on it. When I am driving at low speeds (35 or under) my trucks hesitates like the transmission is in too high of a gear (chugging). The problem is far worse when cold and/or going up a hill at low speeds. Is this typical? Not sure if it's a break in thing or...
  6. Blackstone Oil Report For 6.4 ~7100mi on Castrol

    Oil Change
    Just like it says, I changed oil about 10 days ago and got my report from Blackstone Labs Thursday. It appears that my motor still isn't broken in at ~21K miles and right under a year later. To date I've done 4 oil changes, 2 previous with Rotella 0w40, 1 with Castrol 0w40, and currently it...
  7. Early Oil Change?

    6.4L (392 cu in) HEMI V8 Specific Topics
    Any input on an early oil change? I come from the school of 3K miles for conventional and 5k miles for synthetic on an oil change. That said, I'm thinking of doing an early change just to make sure everything is clean as can be at the 3k mark. I like the concept behind the Pennzoil Ultra...
  8. 6.4L Problem

    6.4L (392 cu in) HEMI V8 Specific Topics
    I've had my truck for a week now and today I noticed something disturbing. I started my truck and I noticed some smoke from the tail pipe. It was a nice spring day. About 64 degrees. I'm sure it was smoke, not steam. Later, I remote started it after it had been sitting for about 30 minutes. This...
  9. 6.4L Hemi 8 Speed

    6.4L (392 cu in) HEMI V8 Specific Topics
    When are we going to see a 6.4L Hemi with an 8 speed transmission? I'm looking to buy a Power Wagon but with Chrysler phasing in the 8 and 9 speed transmissions I don't want to buy the 6 speed and regret it when the 8 speed comes out in the Ram 2500s.
  10. Looking to order a new 2014 2500...

    2014 Dodge Ram Forum
    I'm new to this forum and I figured I'd ask a few opinions first. I've never been a Dodge owner, but I've had a few people that have changed my mind. Currently own a nice 05 GMC 2500HD. I like my truck but I think it's time to update. Here's what I'm looking at ordering: 2014 Ram 2500 4x4...
  11. 2014 Power Wagon with 4.10 gears=Less torque at wheels than '13 model or older

    2014 Dodge Ram Forum
    By performing a simple calculation, I've discovered that the 2014 Power Wagon, although with a more powerful engine, will still have less torque at the wheels compared to a '13 model or older. The reason it will have less torque is that it is losing torque multiplication from the 4.10 axle...
  12. New 6.4 L Hemi MPG Prediction

    2014 Dodge Ram Forum
    Anybody have any predictions for the new 2014 2500 6.4 L Hemi MPG...specifically in a Power Wagon model? I've read current owners are getting 15 MPG on the highway. Considering the 6.4 L is larger than the 5.7 L, it may require more fuel...but it will also utilize the MDS, which may make it...
