What do yall recommend as far as brake fluid goes for an 06 250?

 

Ford has a real high boiling point fluid that is the accepted hi-po fluid. Second to that is Performance Friction's Z-rated fluid by 2-5 degrees. The superduty came with DOT3 and not some fancy silicone based fluid, so a heavy duty dot3 will be fine.

 

I use Castrol GT/LMA.

I've looked at a few brake fluid comparisons, and like ReAX said, the Motorcraft stuff is very good. Its also not too expensive.

 

Brake fluid is one of the few areas I have been able to consolidate everything to one type! Well, except for the motorcycles, anyway.

Castrol GT/LMA.

Very high boiling point (never had it boil in any application, including my "small braked" '99 SD while towing), affordable, and easily available.

 

I just scooped up some Valvoline DOT3/4 synthetic.

 

Worked for me. And had not turned green! Still looks good @ three years.

 

As an aside, all brake fluid is "synthetic"; it's just marketing wankery these days to call it that.

 

I've been using Bosch ESI6-32N, it meets Dot 3, 4 and 5.1 with high boiling point and extended drain intervals $14.61/qt on Amazon

 

I've used whatever DOT 3/4 fluid is on sale at the time I needed it and have had no issues. It takes about 1.5 quarts to do a full flush including replacing what's in the master cylinder reservoir and then cycling the ABS dump valves and bleeding each corner until clean fluid runs out.

A pressure (not vacuum) bleeder makes this an easy job.
