i have 174,600 miles on my '92 cherokee....
i want all the life out of my 4.0HO so i was thinking that when i get the money when i go back for classes this fall and also start back at my good job i have up there.... that i may go the route and treat the engine to autoRX to help with giving the engine its life back.....
as for a few questions...... will it be okay to run the auto RX in with Penzoil's HM oil??
and what oil would be ideal for the whole process?
(i know there are many opinions on this) but should i stick with using high mileage oil throughout all the phases?
thanks!
