Gear Oil/Motor Oil Recommendations Please - AGAIN

Hello fellow Sporty bruthas. I know this has been covered about 1000 times and I had it saved to a Word doc, but my drive crashed a few months back and lost some data.

I plan to start maintaining my own bikes and wanted to get some ideas of who is using what. If I recall, Mobile and Amsoil were the front runners. Mobile 75-80w for gear and I can't remember the motor oil. ...I assume Amsoil 10-40w???

Feedback would be appreciated please.

Been there, done that. There is no shortage of either opinions or attitudes here. Not to leave you without an answer...

Assuming you are going to use synthetic, my choice for top quality products at a good price is:
Engine - Mobil-1 15w-50 (Walmart - 5 quart jug for ~$26.00)
Tranny/Primary - Mobil-1 75w-90 Gear oil (Autozone - 1 quart ~$9.00)

But, to each their own.
