Bongo Fury

The Bongo Fury lubricants factsheet says that the brake fluid should be DOT4, but on the brake fluid filler cap on my Bongo it says it should be DOT3. Who should I believe?

either but 4 has a higher boiling point

I believe Dot 4 has better spec than Dot 3 with a higher boiling point & better resistance to water absorption, but it should be backwards-compatible. If you're replacing all the fluid (as should be done every 2 or so years), then I'd suggest you pay the extra & go for Dot 4.

Thank you Supreme Beings!
