Brake fluid?

[89 fxrs]

2013 road glide manual says to use dot4 brake fluid - would synthetic dot4 be acceptable? Any advantages or disadvantages versus standard dot4?

Most fluids are glycols (except DOT 5) which are alcohols like antifreeze so Like the others discussed I am not sure what synthetic means in this context.  Could be marketing hype.  Use it, it will be fine.

If you post long URL links and it messes up the site formatting it will/was removed. Best to use the URL tags to post links these days.

Usually, the synthetic branded has/maintains a higher boiling point which is good for ABS.

If ABS - Synthetic DOT4 per service bulletin
