The C5 Z manual says DOT 3. I also see DOT 4 mentioned on the forum. Does it matter? Preferred brands?

Thanks, jcs44

You can use DOT4 in the C5Z. I use Prestone Synthetic DOT3/DOT4 from WallyWorld.

I'd use the #4 in both. Good luck, & dont splash any on painted parts!

Thanks. Got my MixMizer ready to go.

What works good w/ the mixMizer, is to take an old plastic container( I like a clear see through) that has a large lid. cut a hole about 1"1/2 in diameter into the lid. It eliminates the chanch of splashing when squirting out the old fluid. Plus w/ the clear container, you can really see how the old fluid looked.. Good luck.

Biggest question is............. what do you do with your car? NO Track? sure, a good 3 or 4 will be fine......... do a lot or road course...... I wouldn't use it!

Why dont you give him a reccomendation,/suggestion of what to use. That is what he's asking. According to his profile he has no mods. Seems like he's at the point of wanting to get rid of his dirty fluids & fill w/fresh. ?

I put Valvoline Synthetic in Friday when I installed my new brakes and lines. It is DOT3/DOT4 compatible and is working good so far. For the track I would go with something more robust but for the street its fine.

Personally, I don't care for the Valvoline. It seems to get dirty too fast. For everyday street use, I like Castrol LMA. For the track, I use ATE SuperBlue or Amber 200. In the Z06, I just run Superblue/Amber all the time. It's a high performance fluid, reasonably priced and I know that short of doing a whole lot of track time, I'm not going to do anything that will out-perform the brake fluid.

In the clutch, I stick with either Castrol LMA or ATE Amber 200. The amber fluid makes it easier to see when it is dirty vs. SuperBlue.

Yep,that's what I use in all my 3 cars(GST,S2K,Z06)....none are tracked or raced.

If you do race,I would use ATE or another fluid made for racing.

By alternating the blue and amber, it is very easy to tell when the old fluid is flushed out. I just changed it this weekend. I used a clear piece of tubing on the bleeder. when the fluid in the tubing changed from blue to amber, I knew that caliper was flushed.
For around $15/quart it's very reasonably priced, and has very good dry and wet boiling point specs. One quart is enough to do all four calipers , with some left to freshen up the clutch fluid.
Speed bleeders, and the drain bag they sell, to collect the fluid, makes the job easy. Didn't spill a drop.

Yes, that IS my question. No racing of any kind for me. Thanks!

I've used the Super Blue and TYP 200 in my street car for four or five years with no issues. I don't drive the car in the winter, so I'm not concerned that it doesn't have the ISO 6 low viscosity spec. If that is a concern for you, use the SL.6 I'm more interested in the wet boiling point.

+1 for Castrol LMA
