Change oil type on high mileage Jeep?

I’ll change the PCV and go 5000 miles between oil/oil filter change. I just need to limp this along until I can afford a new truck. The only thing on the Jeep that doesn’t work reliably is the backup sensors and my drivers side window.

If it were a Grand Cherokee, or a Rubicon, I’d look into a rebuilt engine and keep it.

Over the past few years, I’ve only had to change the alternator, water pump, oil pan gasket and bypass the transmission oil cooler and add an external one. Also added new serpentine belt and pulley.

It should go a long time, provided you keep adding oil to it.

My personal experience, YMMV.

2001 Dodge with the 5.9 Cummins. 170k miles on the clock. Exceptionally maintained with all service records. The truck got conventional oil its entire life. I, against the advice of my two friends, one of which is a former Lexus tech with his own shop, and the other is a Mercedes shop foreman, used full synthetic on the first oil change of the new to me vehicle. That SOB started leaking from every damn orifice within 2 days of that oil change.

Coincidence? I doubt it.
