Complete professional advice, including motor oil, gearbox oil (transaxle) and lubricants for the power steering system, brake system and cooling system. Oil for Jeep (EU) Grand Cherokee WJ Grand Cherokee 2.7 CRD AWD (2001-2005).
When I bought my CRD I changed my oil to Castrol EDGE FST 5w40 full synthetic. I noticed increased ticking (probably lifters) and my oil pressure went down a bit. I didn't quite like it so after about 1000km I drained it and filled with Valvoline Maxlife 10w40 - no more ticking and oil pressure went a bit higher.
