Tnx...will try to change it for a GL4 sped oil in a future
AC1DD said:Now just because the bottle says it covers GL-4, that does not necessarily mean it is a suitable for Manual Transmissions.
So is the CRC Sta-Lube 80w90 GL-4 available at many walk in parts stores in the USA suitable for synchromesh manual transmissions in passenger cars?
Never actually seen that question addressed properly and fully.

I have to say that it does NOT as it lacks the specific friction modifier chemistry necessary to create the proper dynamic friction coefficient for synchronizer engagement.
