I idle my Jeep on a regular basis. Think about it this way, start = no oil, run = plenty of oil. I have 150,000 miles on her, but that could also be because she has a 4.0L in it (indestructable engine).
I was trying to find some 0W-40 RP or GC but couldn't find any I tried 2 walmarts and 1 autozone, all I found was shell rotella 5W-40 SYN so I got it. I would like to hear where you get your oil from.
I'm new here, I've been lurking these forums for a while and found some great info! I'm a member of jeepsunlimited.com so this isn't the first time ive been on forums. So how does royal purple 0W-40 stand up against other oils? Does it have the VII's that shear? How well does it clean? Any other...
