ATE blue and TYP 200 are the same thing but a different color.
They exceed the DOT4 classification by quite a bit when it comes to wet boiling point, and have high dry boiling points.
Mutol RBF600 is 25F higher than ATE on the wet temp and about 60 higher on the dry, but at 1.5 times the cost.
Castrol SRF is VERY expensive, and you wont buy it but it does have a wet boiling point 100 degrees above the Mutol!
if you race the car often, and are going to replace the ENTIRE brake system (even the steel lines) then thats the fluid for you.... at the cost of about $120 to bleed the system.
Racers: SRF
Trackers: RBF600
Everyone else : Superblue/TYP200
Valvoline has a wet point 50F below Superblue and 75F below RBF600 by the way!!! and its dry point is 33F below Superblue.
and that dealer is a lying sack of crap, stay away.
also, Superblue should be DOT approved, because it meets the DOT4 and 5.1 temp, fluidity, and compressibility specs.
