Royal Purple for sure. Awesome performance and engine protection. Just get the weight and viscosity that Jeep recommends in your manual. It is worth the extra money.
My friend bought a diesel Jeep that had to have synthetic. After 12,000 miles that oil was still slippery and did not have the smell that suggested breakdown. He changes the oil filter at 6,000 and the oil at 12K.
