Hey js. I appreciate the info. Many have said a- the 5.7 hemi in the 2500 & the 1500 are identical as far as internals go. But one lacks the computer ability to shut down cylinders. So one begs to ask the question why do they rock the 5w 30 in the bigger capacity truck & not the other. I get it but I believe it's more than just the mds but more so because of the fuel mileage claims would be off.
People in europe practically don't even have 5w 20 weight oil. They all use 5w 30 & say their rams run fine on it & the mds isn't effected. So I just was trying to find some folks who run it over here & how their hemis behave????
