I don't think anyone ever has any problems w/their products, just their marketing. Until recently, they were one of just a few companies that had synthetic 75w-140 available for Ford's rear differential. I saw Valvoline Synthetic 75w-140 at Advance Auto Parts the other day, it was over $14.00 a quart. Mobil 1 75w-140 is becoming more available too and I saw it at Pep Boys a week ago. I think that was around $9.00 a quart. Make sure you get the friction modifier to add into the differential if you have a L/S.
