I've asked before, but what's the difference between THIS and THIS? I was led to believe that "SUPER" was for the MR's six speed tranny. According to the website they are both GL5 90 gear oils for the tcase and rear diff only. Aren't all 05's t-case and rear diffs the same? Why would my MR supposedly require the SUPER oil at nearly double the price? I've emailed them to no avail. Anyone know the answer or used the SUPER Diaqueen and can explain?

 

wow good question! i would also like to know... subscribe

 

why would you charge more maintance money for a more expensive car?

 

My dealer hasn't a clue even though they can verify the part #. No one here knows? I'm sure someone has used it/knows what it's about!
