I must have missed the memo, because to the best of my knowledge the Mobil 1 Synthetic gear lube that I have been using for over 2 decades and over 5000 passes in 2 cars is GL-5 and by some miracle the R&P in my 9" housing under my Firebird in which I 60 foot quicker(1.17 best) and runs quicker than most posting here survived weekly racing for 4 years and over 700+ passes before the pinion gear started to fail.
