Re: 4.0L Mileage/Life
Some of these people that use the higher grade oils believe they
may exceed the recommended oil change intervals. It's fairly easy to
change an engine every ten thousand miles and change the oil at the same
time.

Campbell,
No, I still use synthetics and AC filters, but I believe the root cause for
engine failure was a defect in the head. Only after I made the dealer add
coolant when the bottle was empty(3X in 3 weeks) did they actually believe
me. I had to force documentation to get somewhere while still under
warranty.

Mine has 170,000 km and I expect to get that again with no trouble.
Just do the recommended services and make sure you change all of the
radiator and cooling hoses at about 120,000 km, and you should have no
problems up to at least 300,000 km (that's km, not miles)
That applies to most engines, actually.
