Help me choose a fluid. Volkswagon VR6

[CagedVR6]

Im trying to figure out what gear lube to run. I drive a 1997 GTI VR6 with a Quaife limited slip. Requires a GL4 and something like 75w90. Ive ran redline for a few, and it worked great until longer driver "1hr +" where it would want to grind 2nd if i dint double clutch. I swaped that out for some GM syncromesh friction modified and now it wants to grind 2nd all the time. Should i of not got the friction modified? Any recommendation's on what fluid to try next? Some have seemed to have good luck with just normal non-synthetic gear lube. What non-sythen 75w90 gl4 could you recommend? Ive been considering Amsoil royal purple bg-syncroshift

According to the Amsoil online guide, your car requires 75w-90 wt fluid. Syncromesh fluids are too thin for your application. I would drain it out as soon as possible. I would contact a sight sponsor and get the Amsoil GL-4 fluid. Gets great reviews here.

Here's what I recommend: Amsoil MTG 75W-90

I have a liter of VW GL4 gear oil sitting in my garage, as well as a fuel filter and 2 oil filters both Mann filters. I don't have the car anymore. If interested PM me.

The O2A in MK3 VRs always grind 2nd gear. IMO I've always had good luck running Redline MTL.
