I knew about the MDS, I didn't know that was the reason why the Hemi's used 5W20. Unfortunately, I don't know as much as I would like to, particularly where the Hemi's are concerned.
Ah...well yes, the MDS system requires 5w20 since it solely relies on oil pressure to activate/deactivate the lifters. Too heavy and it can't properly work with the tiny valves. If you've disabled the system or even removed the solenoids then it doesn't matter what oil you run. I've heard some of the Hemi car guys have run 5w10 and still be okay since it's a lighter oil.
OK I ran the scan P0522 oil pressure switch/low voltage.
One of the same codes I got! At least you know your oil system is fine so nothing's going to go bad or get destroyed before you get the sensor changed. Just make sure you get an official Mopar one.
