Red Line Oils

[TRXMaddness]

Has anyone ever used this oil brand in their 400EX? I just spoke with a technician there at Red Line and he said for the high temp like the 400ex it would be best to use a 10w40 for the wet clutch.
If anyone has used this oil please give me some response on this oil.

Redline is the best oil out there in my opinion. I use it in my Cannondale and my wifes 400ex. I use the 40 wt race oil. Summitt Racing sells it.

I run Amsoil 20w50 V-Twin fully synthetic in my 416. It runs alot smoother with the Amsoil. It takes alot of ride time to break it down too but it is pricey. Great oil, the best i've used so far.
