Trans, F&R Diffs and T-Case oils???

What brand of synthetic oil would give me a longer oil life than the Mopar oils??? I think it's pretty ridiculous that the life span of the Mopar oils are so short. I've been thinking of switching to Amsoil throughout, including engine oil & filter. Any opinions???

T-case needs to be mopar, no aftermarket options available. As for the other stuff, I'm running royal purple in the diffs and mobil1 in the engine, and K&N as a filter

Thanks for the reply. I'm currently running all Mopar in everything besides engine, which is Mobil1 oil & filter.

This is the 1st Mopar vehicle I've owned in nearly 20 years. A lot has changed. After some reading I think my local shop's maintenance schedule is a bit excessive when compared to the maintenance book. I'm gonna follow what's on the WK site but still do my engine oil every 3000mi/5000km. I'll post up the schedule they have me on later tonight.
