Total cost was $8.00 for the 32 oz bottle of synthetic brake fluid

 

I would of opted for DOT4 vs Synthetic brake fluid. At least with DOT4 you can withstand more brake fluid temperature and few other bonuses. DOT5 is the extreme brake fluid with the highest boiling point for brake fluid.

 

Most applications call for a DOT3 (401F dry/284F wet) or DOT4 (446F dry/311F wet) fluid, which is considered a higher performance fluid since it can handle more heat. While both fluids are glycol ether based, DOT4 contains a certain amount of borate ester which allows it to handle more heat.

 

DOT5 is a silicone-based fluid that was developed for use where moisture or water was almost certain to be a factor in the braking system, such as military applications. While DOT5 has a higher boiling point (500F dry/356F wet) than DOT3 or DOT4, DOT5 exhibits more compressibility than glycol ether brake fluid. There are DOT4 fluids with boiling points that exceed DOT5 so there’s really no need to consider using DOT5 for on-road use.

 

DOT3 and DOT 4 cannot be mixed with DOT5 fluid. They are incompatible and if mixed, brake failure may occur.  Moreover, there are serious compatibility issues when using DOT5 in a system that was engineered to use DOT3 or DOT4. Also, users should take care not to mix DOT3 and DOT4 fluids as there may be brake system compatibility issues. Always consult your owners manual and use the type of fluid specified for your vehicle.

Last time I used valvoline dot 3-4 synthetic, this time I got some supertech from wallmart in dot4 synthetic. Guessing there is no difference in brand name other than price. I'll give it a try and see how it goes. 

Edit

Not sure how it's both at same time

Ok ,,, good on an exhaust brake and long pad life

 

I am another who has logged over 200,000 miles on front brake pads, rotors, and calipers.  I replaced the pads and rotors at 215,000 miles just as a maintenance procedure - there was at least another 50,000 miles left on the pads.  I am still running the original front calipers, now at 332,000 miles. 

 

And of course, I do have an exhaust brake and it gets used every time the truck is driven.
