I have a 95 neon, 180,000 miles on it. For the record, factory oil fill is mobil oil* those mopar quarts are re badged mobil 1*
Ive used so many differnt oils, and found..valvoline full synthetic to give my neon the smoothest quietest running engine.
It dosnt seem to like Ac delco filters or the orange oil fram filter. Many times, ive put a fram orange on, and the oil light lights up. never with any other filter has it done this. I do LOTS of city driving. The ecdelco, hard to explain, neon just dosnt seem so alive with it.
Purolators are awesome actually. Yuo can get a mopar filter, bu at $9 and up for one, i still get valve chatter. Right now, i am using a NAPA race car filter for my neon, its a black can with NASCAR printed on it..minimal valve chatter.
