Is Castrol Dot 4 brake fluid OK for the clutch fluid in my 2011 Grand Sport?

Yes that’s exactly what you need any brand of dot4 though

Yes. Make sure to keep it clean. It will make the clutch and slave cylinder last a lot longer. See Ranger method.

I flush mine about once a month during the months its being driven. Its black every time, maybe I should update the frequency.

Yes, keep that clutch fluid clean, don't learn the hard way like I did hoping the master cylinder wouldn't pop. It's soo much cheaper and easier to maintain than going through the down time and pricey fix. Unfortunately mine failed a year after the extended warranty.

I've always used Pentosin Super Dot 4. Higher boiling point. The Castrol is fine, especially in a street driven car. Agree on the Ranger method to keep it clean

Is AC Delco 10-5031 (89021185) the only choice for p.s. fluid ?

Any Dot 4 should do...stick with name brands though...In the Corvette factory when I was there GM used DOW...In gigantic plastic totes. I use Prestone from Wally world...
