I just switched to Mobil 1 5-30 Syn. How often should I change the oil now? Thanks ,Rich...

When it says to in the owner's manual depending on how you drive.

If you change to Amsoil you could push your change interval out to
15-25,000 miles. Since Mobil 1 doesn't test as well as Amsoil though you should probably keep it at 5-8,000 miles or so.

What JJsKJ said. Since it takes me 6months to go 3k miles, I change mine every 3k miles. If you put alot of miles on you jeep then Id go every 5-6k..

If anything ever happens to your engine they may be alittle picky on the oil change though.. You have a power train warranty for 7yr/70kmiles..
