500 miles -- change to synthetic oil?
Hi everyone!
Well, I'm changing my oil -- diffs, t-case, trans, engine -- and have to decide if I stick with the manufacturer's recommended oil for another 2k miles, or switch to synthetic now (including a larger oil filter). What are your thoughts? Too soon? I didn't baby the engine, so it _should_ be broken in now, right? I'll probably go with Mobil 1 all around...
Thanks,
js.

I switched to Mobil 1 full syn at 4000 miles. i figure its broken in now, and eventually will convert the tranny and diffs/transfer case etc to full syn if I can.

Anyone know the type of oil that goes into:
- The manual transmission
- The transfer case
- Diffs
- Engine: I'm pretty sure this is 5W20.
Any truth to the rumor that the oil from the factory is 'special' for the break in period?
I figure at 500 miles it's time to get the original oil and metal shavings out of there. At 2000 miles I'll switch to synthetic...
Thanks!

This is highly subjective, but I think it was around 2000 miles before I noticed that my engine had noticeably better performance. I attribute that to being properly broken in by that point. Consider: Once you switch to synthetic, break in will stop. I wouldn't recommend switching before 2000, and have always waited until 5000 miles for all of my own vehicles (I've been running Mobil 1 in every one since the mid-70s). I will switch to synthetic in the JK at the next oil change: 6000 miles.
