About to take off on a long vacation drive with 2014 GC Summit diesel.....7500 kms on the vehicle and thought i should check the engine oil level before the trip just in case it needed a topup. Pulled the dipstick and ca me across the blackest engine oil i have seen in years.....literally black on a white rag....it feels thin to the touch as well. Is there any reason.....this is my first diesel......that engine oil should be any different than in a gas engine?

Yes, diesel oil is different than oil used in gas engines.
Diesels suspend soot into the oil.
Black oil in a diesel engine is a sign that the oil is doing its job. (Soot suspension.)
Black = good.
A diesel engine's oil will usually turn black as tar after a few hundred miles.
Nothing to worry about. Just keep the oil levels correct, and change the oil at the manufacturer's intervals, or when the gauge (if equipped) tells you to change the oil.

Concur completely.

Never had a diesel that didn't have BLACK OIL.

Have had 4(four)

Jeep liberty 2006 CRD, The new JGC 2014 Eco diesel and two(2) Ram Pickups with CTD. Always change oil a little earlier than required and have NEVER had a problem.

Not to worry.
