NOTE: They carry universal DOT 3/4 which is not compatible/recommended for our brake systems. That is why Jaguar calls for a specific product.

Oh, and those products will not work on our cars either. They must be Super DOT 4, which has higher specifications for boiling points and viscosity.

Sorry, didn't see the 'super' requirement. Still lots of choices available though
super dot 4 - Google Search
Having said that, I can find no definition of 'super' dot 4 specifications. Many contended that it's a brand name/marketing thing.

DOT
Department of Transportaion
Here is the specification:
Standard No. 116; Motor vehicle brake fluids. - Federal Motor Carrier Safety Administration
For 3 and 4 there is no difference other than boiling points. There is no such thing as "super" in the specification.
There is a Ford specification fluid often found on shelves which has a boiling point of 550 degrees fahrenheit. That gives a useful increase in headroom.
The BMW fluid is also quite good, cheap, and comes in nice 1 litre resealable metal cans. A good second choice to Motul when Motul is not available.

Jaguar is famous for specifying proprietary products not available universally. They do it under license to help sell the products and getting a break on the factory fill. They care not that you anguish about finding the stuff! DOT 4 is Super DOT 4 as far as brake performance goes. I alternate between pentosin (clear) and ATE racing blue so I can tell its been changed. All DOT 4's have the boiling point and viscosity needed. Not to worry about this one.

Well, I am certainly no expert in this area, hence the reason for posting here, looking for feedback from those who have experience. Normally I would just pay the dealer the $300, but I think this is a fairly easy maintenance to perform and since I enjoy working on this car, why not save a few bucks.
Jaguar does specify the exclusive use of Super DOT fluid and there are a handful of manufacturers making the fluid. Checking spec sheets indicates there IS a difference and for the few dollars more, I would rather lean towards the specified fluid. The challenge is that it is not readily available.
I am intrigued by Motul DOT 5.1, found on Amazon. It has the highest specifications I have seen and is indicated as been a long life fluid.
Oldmots - no doubt this frequently seems to be the case, but if using better products prolongs the life and serviceability of the vehicle, why not? I do like your idea for using a different coloured fluid for brake flushes.
And while we are at it, a little controversy. Many indicate that vehicle fluids break down over time due to heat and everyone agrees that brake fluid is hydroscopic, resulting in contamination by moisture. Moisture then contributes to internal corrosion, changing fluid prevents this from happening, of course. But if a brake system is sealed, how does moisture get into the fluid?
