Wanting to go to a higher temperature fluid but master cylinder
has warning use only dot three.
The high temperature. stuff say it exceeds any dot. Why couldn't you use the higher temperature Stuff ? Thanks

 

You can use Dot 4 or 5.1 with out a problem as far as I know.....

 

Thanks, it is just a replacement m/c from AutoZone.
Tandem .

 

I found dot 3 high temperature. Fluid from Wilwood. 550 or something like that. Should help protect the fluid.
