So I have about 13k on my D and I'm getting ready for my 3rd oil change at the deaker. The dealer told me that they use Mopar oil in there changes and that they recommend 5k or 5 months and I wanted to know if anyone knows if the Mopar is synthetic or if its synthetic blend or am I basically using regular oil at this point.

 

it might just be pennzoil probably the syn, but wouldn't hurt to ask mopar or the dealer..I'd be curious if its the ultra (doubt it) or maybe just the Euro or platinum blend
