cheap brake fluid for temp use?

[Ill 3.0]

I've been waiting to install front BBK for a B6 S4 rear kit to come in, but that rear kit has been delayed. So I don't want to wait anymore. Can I pick up some cheap Dot 3/4 fluid (local Autozone or similar) to use for a couple of months, or should I suck it up and order 2L of pentosin from ECS for $20-30? I believe it takes just about 1L for a flush, so I should probably have at least 1.5L handy, right?

It won't hurt.. but why do the same job twice? If you are going with the pentosin from ecs, then you might as well do it now other than later...

Any DOT4 fluid will be fine.

What about a Dot 3/4 like Valvoline?

I'm doing the same job twice since I have a Brembo 355 sitting in my garage and don't want to wait for the B6 S4 rears. Also, I wouldn't leave the Pentosin in, I would switch to RBF 600.

Super Dot 4 is relatively cheap.

cheap is relative to the cost of the repair going cheap in the first place creates :)
