Hi,

What oil do you guys use? The manual recommends 5W-20 for my JK but the dealership has been using Caltex 5W-30 Eco 5. It conforms to the Chrysler MS 6395 specifications.
I really want to start doing the oil changes myself. The JK is still under warranty and I'll probably void the warranty however it is becoming just too expensive to have it serviced by them.
Any thoughts would be appreciated.

Cheers

Penrite??
