505 BA10 Transmission oil

Let me know what you guys use in yours. I think that regular motor oil is recommended. I'm using some castrol 10-30, but i wouldn't mind experimenting with something else. My gears don't feel all that happy. They are kind of chunky and it has a hard time getting into 2nd sometimes.

Redline 80-90 NS gear oil.

The NS means No-Slip - it's a friction additive for the synchros. I run it in my 505 STI ICE/Dirt racer and the BA/7 in that car is the slickest shifting tranny I've EVER experienced. It gets flogged with two other guys besides me and it awesome - even in -40C race days! (So no worries about it being too heavy - plus gear oil uses a different viscosity index so it's closer than you think.)

Bonus is running it in the LSD - locks up the LSD quite a bit more than stock... :lol:
