Does anyone know if the Mopar 5w20 is dino, a blend or synthetic oil? My dealer told me it was blend but i would not count on that as they did not know it needed 5w20 in the first place.

I don't believe there is a Mopar 5w20. While they may list a Mopar part number on the bill my dealer uses Castrol.

Yeah, Cool, Castrol is on my oil change invoices. Fully synthetic 5W20. I would preffer Mobil 1 0W20, but whatever.

The Mopar brand oil is dino. Regardless of dino/blend/synth, better follow the service schedule in the manual (and document) to guarantee warranty coverage, just in case. For most of us, that's gonna be every 3,000 miles or 3 mos.
