Ram Engine Oil QUestions

I just upgraded to a 2014 Ram 2500 Hemi 5.7 yesterday. It does NOT have the MDS system. In reading the owners manual, it says:

Use 5w20 oil unless GVW is 14,000, then use 5w30.

Well, I am over 14,000 pounds with my RV, but certainly at 6,200 pounds without it. Certainly, I am not going to change my oil every time I tow...ugh:roflsquared:

SO, I am thinking that 0w30 all around my be a good middle of the road deal....anyone have any suggestions??? Thanks

  • Use the oil that the Owners Manual recommends.

    Why do you say it doesn't have the MDS system?
  • I'd use 5w30 year round towing or not and not worry about it again. Just my 0.02.
  • The 5W-20 is just for their fleet fuel mileage requirement, 5W-30 is always a good choice. I'd use it until the high temp during the day was zero and then go to a 0W-30, maybe.

  • Unless you tow during the winter months in the Alaskan interior 0W30 is the wrong oil. Check the temperature range where they recommend you use 5W, it is likely well below freezing. And no, nobody expects you to change the oil every time you hook and unhook. If you are consistently towing heavy loads use the heavier oil. 10W30 is just fine for most gassers in the spring, summer, and fall.
