It requires DOT3 fluid, you do not have to buy it from Honda.
Thank you. Owners manual says if emergency you can use other but replace with Honda asap. something about could get corrosion with non-Honda brake fluid.
Any DOT3 fluid will work fine. There is not a measurable difference in brands of brake fluid.
Thank you. Appreciate the information.
the power steering fluid is the one you have to be careful with.
Thank you. I wasn't aware of that yet.
