Hey there, I am getting ready to do the 60k on my '05 EM and flush the old fluid out of the brake system as part of it. I was going to go with the trusty Castrol that I have used for years, but the shop manual says not to use anything but Honda fluid or I might get corrosion in there. I don't think Castrol would make brake fluid any more corrosive than Honda's so what do you all think? Thanks!

 

Any DOT 3 is fine.
