Gear Oil.... Prefernce Poll
I dont see any polls for what kinda gear oil everyone prefers for Transmission and Differential. So here it is. I know a lot of you guys argue back and forth on whats better so now we will find out! Im not referring to whats best for race prep cars, just the daily driver/sprited driving community!

DO NOT use royal purple maxgear in you're tranny.
I switched from OEM tranny fluid to RP maxgear and I started getting 2nd gear grind. I switched to Red Line MT90 and the grind was gone after 2days.

I'm using RP Maxgear. I started off putting the 75W90 in the tranny and rear end.
I started having problems putting it in gear especially after a run in autocross. I switched to RP 85W140 and the feel is perfect. It even goes into reverse now when its cold outside on the first try. I still have the 75W90 in the differential though. I'm thinking about maybe getting the KAAZ gear oil or replacing it with something thicker.
When I was using the lighter RP it never would grind, just would not go into gear. It did make a whiiirr noise though. Maybe no one should put 75W90 in their transmission.

I believe Red Line is GL-4, which is better for transmissions that contain brass parts. My first fluid change was to Royal Purple. Would make a noise when shifting to 5th gear. Changed to Red Line, and the noise went away after a few days.

Shell Transaxle Oil, 75w90.
Not very commercial but is used as the differential lube in the ferrari challenge.
Put it both in my shift and my differential while mounting the final gear.
It really changes the shift feeling and doesn't soften after 40minutes of continous track drive.
I really suggest it!

I really want to try this: http://www.fcsdchemicalsandlubricant...ission%20Fluid
The 6 speed Miata guys seem to really like it, and as we all know our transmission is pretty similar to the 6 speed NB tranny.

I got some Amsoil 75w-90 GL-4, going to try to have it done this weekend. Probably gonna have them do a BG flush to get out the Maxgear. My 2nd wasn't great before, that's why I switched to Royal Purple, but then 2nd got worse and other gears started shifting bad at times.
I'll let you know how it goes.
