I am considering running the RP Syncromesh in my manual transmission but do not know how cold weather will effect this fluid. Would i be better off running the bmw MTF-LT-3 due to the cold winters here in canada, or would the Royal Purple be fine? Thanks
I can't answer that since I'm in Arizona. But I'd suggest that the Redline fluid for your gearbox (it's one of their AT fluids) would be better than the BMW fluid. Turner Motorsport put Redline in my E46 MT gearbox when I lived in Boston and it was much better than the factory fluid in the cold.
