Hey guys,
bought some Royal Purple 75w90 for the rear differential on my 2003 Montero Sport Limited....it has a LSD but the Max Gear fluid says it already has friction modifier in the oil. I read on some other forums that people needed to still add friction modifier to the oil. Anyone here have any experience with this oil versus the Red Line? Do I need to add more friction modifier? Are friction modifiers universal with all oils?

Am I really the only one crazy enough to buy this stuff and put it in the rear diff? I'm gonna try it this week when I get some free time...I'll let you all know how it goes and if I get chatter or not.

Volvoline or Amsoil are cheaper. The answer to your questions, though, is unless you're getting chattering from the clutches - no, you don't need to add additional friction modifiers. I run Amsoil in my Sports and have for a long time. No issues with having to add anything. Edward |

Well I guess I justified the RP since I didn't have to buy my wife a new SUV yet...haha.... I'll let you all know how it goes. I'm playing single dad for the moment so its hard to even find 15 minutes to get the job done.

3000 miles later and still no chatter.
Seems to be doing alright without additional fiction modifier

RP has a friction modifier added to it from the plant.....not sure how good it is or if its enough, but at the moment it seems quite fine.
