A gear oil would be a lot quieter if that bad, I'd use that before forte myself, but as it's needing a build anyway might as well just put some forte in and see ?

I think I might just stick some normal gear oil in and see what it sounds like. If it recks the synchros, long term then, they will just get changed. anyway. Whats the best gear oil to try, just standard 75w90 ??
