Honda owners manual says use Honda Extra Duty brake fluid. Is it necessary? on 2010 Honda Odyssey

is there really a difference in brake fluids or is this just a Honda marketing ploy

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.
