Need your advice, bardahl fluids for my vette.
Good day, need your advice: I heard great feedbacks for bardahl fluids but never met any vette who tried to change diff and manual transmission for bardahl. Please share your experience, is it better than GM? I am going to change all the fluids, just trying ringing out what is better.
Thx!)

I can't answer your question about bardahl, my skill levels are quite low.
Even at my pitiful skill level, I would advise that any fluid recommendation for your car have a very detailed reason why it is a better choice than factory fill.
Consider, for simplicity sake, the GM fluids are the correct fluids. Any other fluids are not correct. Other fluids might duplicate the exact function, or excel in function, but unless you know what is going on in enough detail to make an informed decision, my skill level requires the right , wrong simplicity of GM or not GM.
Many people here with high understanding of lubrication that post here can give better advice easily. For instance, on advice posted here that triggered my own facts checking, I will switch from Mobil one, to another motor oil that excels.
I haven't heard about Bardahl since back when old used cars burned oil by the quart and you carried extra radiator water on your front bumper. They used to sponsor an Indy car, back when you read about the big race in Life magazine.
Are you serious ?
I can't imagine anyone worked up about the excellence of the product line, I hope things have changed . I have never seen a gear oil from that company, just the mechanic in a can car repair stuff.
You can mark me down for a "No".

It depends on what fluids you are changing. And in many cases more slippery is not better.
In particular the differential and transmission need the correct amount of friction to work correctly. Both the synchro's in the transmission and the limited slip clutches in the differential need the right viscosity fluid with the right static friction coefficient to work properly.
If the differential has too slippery a fluid, the clutches will slip and the clutch pack will wear out in very short order (been there and done that, and had to write the check).....
If the transmission lubricant is too slippery, it will be hard to shift and the synchros will wear out sooner.
These are just two examples where "snake oil" lubricants can do more harm than good.

Only "special" requirement is synthetic in the engine. No additives needed or recommended. Everybody has their favorites, I run Mobil 1 HM 5-30 in the engine, plain old Dexron III in the 6 speed, and the Mobil 1 gear oil in the rear end.
Be careful on the Dex III - you need real Dex III not the current Dex (Dex Vi) which says it supercedes Dex III, but is a no-no for MT boxes.. GM sells an MT fluid, which is basically their old Dex III. Many swear by Amsoil in the trans also. If this is an early car, it will not like synthetic in the MT6 - you will get gear grinding, etc.
