STP S16 filter from a 1992 Jeep Cherokee 4.0L my friend recently bought. The Jeep has 52,000 miles, and according to the service records from the previous owner, this filter was on for about 3,000 miles with "10w30" not sure which brand, and about a year. The media looked good, but the nitrile ADBV was hard as a rock, and the engine had a nice rattle on start-up. It was replaced with a Fram TG16, and Fram 10w30 high mileage oil which cured the rattle.
