i got a deal on some royal purple oil and picked up about 5 quarts of 10w-30. i wanted to know if i am going full synthetic, what grade gear oil do i use and does royal purple carry a brand? what about differential fluid changes? 10 - 30 ok?

75w-90 Royal purple for gear oil. You can pick them up for around 12 bucks a piece and you'll need almost 3. If I remember correctly it's around 2.75 quarts
