Royal purple syncromax update.
So its been around 3 weeks since I change my manual transmission fluid from OEM to Royal purple and while shift quality remains about the same (smooth) it helped greatly on transmission noise! With the OEM fluid when the tranny got hot if I put up the windows and turned off the ac and radio it was pretty loud and quite disturbing, almost like you could hear the gears turning in the tranny. The Royal Purple seems to work extremely well under intense heat as now noise is down considerably when it gets really hot. If anyone runs there car in intense heat for a period of time and listens closely with everything off and windows up for some excessive noise from there tranny I highly recommend Royal purple. If your notchy it probably won't make it much better but it seems to deal with the heat so much better than the OEM dual clutch transmission fluid.
