When I bought my NSX about 7 years ago, the previous owner had been using Motul RBF 600 Dot 4 fluid, which I have continued to use (from a new sealed container) when I replace the fluid every other year.
Several weeks back my 2011 TL with 80k developed a seized caliper. I had previously replaced the brake fluid with a Castrol Dot 3 about 30k before this happened. After replacing both front calipers as well as the rotors and pads, I found in the TL owners manual that only Honda Dot 3 fluid should be used. It went on to state that an aftermarket Dot 3 or 4 was acceptable only as a temporary replacement (sealed container) and should be replaced as soon as possible with Honda fluid to avoid corrosion. So I installed Honda fluid.
Now it is time again to replace the brake fluid in the NSX. The NSX owners manual makes the same statement about only Honda fluid to avoid corrosion. Do I need to only use Honda fluid?
