There have been reported issues with the synthetic oils leading to flat-spotting the rollers on the MDS lifters when they bleed down for 4 cyl mode. It is related to the synthetic oil being too slippery to provide sufficient friction to keep the rollers rolling.Ddaddy what makes the convectional better for the MDS? I have been using Mobile one Synthetic in my 2014 RT since its first oil change. It now has 97K miles on it. Did they change something in the design in 2014? Not criticizing Just trying to learn
Have been using Pennzoil Platinum 5w30, or Ultra when I can find it, for 5 years in my 2015 Ram 1500 5.7. No problem with MDS. Oil changes annually or 7500 miles.my 2013 5.7 calls for 5/20 CONVENTIONAL Motor oil. getting a litte hard
