Rotella, Delo, Valvoline Royal Blue, Amsoil - all 15w40 will work just fine. Just keep it changed. <br><br>I swapped over to a synthetic in the diff. I am using amsoil now but in the past I used mobil 1 and still put 1 bottle of friction modifier.

Re:engine and rear end oil choices
Amsoil offers 2 different lubes for the rear, one for LS and one for open rears. You should not need friction modifier with Amsoil.<br>I'm running Amsoil front to rear, but do not have an LS in the rear.<br>I just changed my engine oil with 16K on it, and took a sample. The analysis came back stating I did not need to change the oil. I'm goin for 20K this time, and will start sampling at 15K. ;D<br><br>Chris
