I like Royal Purple but I'm having a hard time keeping it in the diffs for long enough to get the full benefit, which is long life. :headscratch:I end up swapping components more than I'd like to. I should filter and re-use it...This stuff is like $10 a quart

It did make my detroit locker operate smoother using the Royal Purple...

It seems to leak its way past the seals easier too.
