What's the best brake fluid without going to a silicone racing fluid?? Are old, sealed containers of SynPower still good after a few years in my damp garage?
Best Brk Fld Now That SynPower Is Gone??

Without spending an arm and a leg, I like SynPower and that is all I have used for along time. I think it is as good as Castrol SRF for your average road iron which sells for many times more. As to the sealed containers, they would be fine to use provided the original seal was not breached and the cap is on tight. Just because brake fluid is hydroscopic doesn't mean it's going to draw moisture right past the plastic, though some might tell you this happens. I would use it.
Motul RBF600 is probably good choice. Obviously, it will depend on what you're doing. Castrol SRF is another good choice, perhaps the top top tier.

There's a drug store near me that still has tons of Synpower on the shelf.

Nothing good about silicone brake fluid except for a system designed for that fluid. It has two drawbacks...it compresses more than conventional fluid so it gives a somewhat spongy pedal feel and works poorly with ABS, and it lets entrained moisture puddle at the bottom and rust calipers and pistons.
ATE Super Blue is the best bang for the buck, hands down. 530-ish dry boiling and 400-ish wet, DOT 4, $10-#12 per liter online. Unless you are open tracking your car, this is all you need. Motul 600 is very good, more expensive for smaller quantity, so I'd use it if you were open tracking/road racing only. Brembo 600 also has a very high dry boiling point. Amsoil 600 has temp ratings similar to Motul, but the Dealer/PC price is less for similar quantities. SRF is uber-expensive. I think a previous poster was refering to Castrol LMA, that's the store bought stuff.

I will probably start using the Amsoil stuff at some point. It's pricey but it is what's keeping your car from wrapping around the nearest telephone poll.
The specs on the Amsoil fluid are very good. Just can't buy it at the local Autozone.

The best off-the-shelf store bought fluid since Synpower was discontinued is probably Castrol LMA.
They changed the formula a few years ago, and the specs just about, if not quite, match the old Synpower.
If you dig a little further, you may find Pentosin Super DOT 4 brake fluid, which has similar specs. Coincidentally, both the Pentosin and LMA are made in Germany and have very similar, if not identical specs, which could suggest they are one and the same.
Then there is Wagner Severe Duty, which is a 5.1 (non-silicone) fluid.
A good local Euro-focused supplier will have Ate Super Blue, or better yet, Typ 200, which has always been the best balance of performance and price. It's worth ordering even if you can't get it locally. The Super Blue is dyed blue, which can discolor reservoirs, and is not DOT compliant, but otherwise identical to the amber Typ 200.
Ate also has a lower-level SL fluid, but if you're going to the trouble, might as well get the good stuff.

Which one would you pick, I'll try and find it. The Wagner sounds like it would be more available to me, not too many Euro parts stores near me. I also don't want to pay the price of a brake job for the fluid alone. Do you know why the Super Blue is not DOT compliant? Tnx for all the info.....
Is the replacement worse than the synpower version?

UPDATE!! Called Valvoline and they said that they just dropped the name SynPower from the brk. fluid and that the formula is the same. Qt Pt.# 601458. Other products were not so lucky, they had a great lube spray, brk cleaner, oil additive and syn.pwr steering fld.

You were right, sorry. I didn't click on your link and ASSumed that it was non-Syn.

Silicone brake fluid is NOT usually an upgrade, especially for a street car!
Concerning brake fluid, I use anybody's [with the proper rating - DOT 3-4, maybe 5.5].
If the rating is correct, I have no concerns at all.

I believe (from what I've heard in the past), that the actual blue dye is the only thing keeping Super Blue Racing from being D.O.T. compliant, but this may be wrong.
Anyone??

Hmmm, did Wagner buy out Ferodo, or was it vice versa???
DS2500s at your local, generic, auto parts store anyone?
