[QUOTE="Deleted member 17706, post: 1395752"] Purple Royal will not out perform AMSOIL diff fluid. I run the 75w-140 too. Most people don’t think about changing their diff and transfer case fluids regularly. I wouldn’t go more than 30k miles on the fluid—especially if you tow and off-road. AMSOIL put out a service bulletin several years ago which stated you should change your rear diff fluid after 5k miles because that is when most of the break-in and damage occurs: [URL='https://www.amsoil.com/techservicesbulletin/drivetrain/tsb%20dt-2006-06-29%20differential%20oil%20change%20after%20initial%20break-in.pdf']https://www.amsoil.com/techservicesbulletin/drivetrain/tsb dt-2006-06-29 differential oil change after initial break-in.pdf[/URL] Also, when changing your rear diff fluid, you need to take the entire cover off. Yes, it is nice having a drain plug, but a ton of fluid is still left in the bottom of the housing. So that could of contributed to why your fluid was so nasty. I also spray all the gears off with brake part cleaner to remove any oxidation and fine particles which may still be on the gears. Good job staying on top of things! [/QUOTE]
