:mug: What brand of DOT III brake fluid do they put in our Z06's at the factory? Is it synthetic? I am thinking about flushing out the old for some new but don't know what kind to buy. Thanks. :cheers:
Don't take this as the final word but ...
Factory DOT III is not synthetic.
DOT IV is synthetic and will support higher dry and wet boiling points.
If you move from DOT III to Synthetic, get someone with a Tech II device to ensure you clear the ABS on first fill.
Do NOT use a silicone-based fluid.
