I just replaced the stock gears in my 99 convertible with 4.10 gears. I put the oil in that the manual calls for (80-90) for break in , but what oil should I use after that. Any suggestions or recomendations?

80-90w again. I would put in a synthetic type too (Mobil, Redline, etc). Don't forget friction modifier if the oil isn't mixed w/ it already.

Yeah, the Motorcraft 75w-140 is a synthetic read diff. fluid. However, you can buy the other brands for cheaper. Why that is, I dont know.
