Guys, I picked up a new to me 2008 cream puff Ram 1500. When I got the truck it had a fresh oil change (conventional dealer 5-20 penzoil). Truck seemed to used about a pint in 6000 miles. I swapped over to my bulk synthetic I used in my 2010 from 20,000 to 140,000. It used no oil to speak of but they did reformulate it to meet Dexos between now and the last truck. When swapping to the synthetic the truck is using about 1qt every 1000 miles. I meant to swap to PYB 5-20 but the store had oil stacked all over and ended up grabbing a 5-30 case on accident. Already dumped one quart in so I figured why not as that was my next step if the 5-20 was still using. My uncle is a Powertrain testing engineer for Chrysler and several of his co workers have ran 5w-30 in their 5.7s since new with no issues. I am about 250 miles into this change with no CEL and the MDS seems to working as much as it normally did. Pressure on the gauge is slightly higher at idle and speed until its fully up to temp then it shows normal at speed and normal to a tick higher at idle depending the type of driving you are doing. I will report back on the oil usage. Still need to swap in a fresh PCV valve and open the throttle body to clean and check for oil evidence. No smoke or leaks on this engine at all aside from a puff once in a while on start up. (red truck did that too and it was very common on new Hemis from my younger days in a Chrysler dealer). Just for reference: Purchased at 58,000 miles now just south of 74,000.
