After experimenting with different oil & oil filter combos for 1995 Jeep Cherokee with 4.0L I6 engine - I finally found my winning combination :
(Drum Roll please) ... Pennzoil 10W30 High Mileage Conventional Oil with Fram Toughguard TG16 oil filter (TG8A oversize) run at 5K mile OCI . The engine (200K+ miles) runs smooth ,oil has great add pack , good cleaning , good oil pressure , no leaks , cost effective . * For anybody with an older Jeep with a 4.0L I6 engine - you would be hard pressed to find a combo oil & oil filter you like better than above . At the very least , the above combo should be on your short list of combo oil & oil Filters to try !
