Synthetic Diff lube

For your consideration, I use synthetic in my diffs (Red Line 75W90) and it's worked perfectly. Since synthetic has superior properties to any dino oils, I run it in both cars (500E with some limited slip, 300TE with open diff) and have had zero problems in 130k miles (100k wagon, 30k 500E)and counting!!
