the newer chrysler products have some version of Pennzoil as the FF(IIRC), and alot of the dealers have switched over to Pennzoil.
unless it specifically calls for synthetic, you can't go wrong with PYB and a wix filter, in the weight called for in the manual (likely 5w20), @ the specified intervals.
if it does specify syn, PP.
I know my neon's little 2.0l felt like a whole different car last summer on PYB, than on the valvoline that i had been using prior. now it's loving the formula shell i just put in.
really any major brand oil should be just fine. all depends on how the owners "butt dyno" feels. or backed up w/ a uoa.
