Power Steering Fluid for Honda Accord 1990

Honda Accord LX 4 doors, Automatic Transmission, 181,000 miles. I have low power steering fluid in my car and want to add more power steering fluid to bring it up. The owner's manual says use only Honda power steering fluid and don't use ATF type and other brand power steering fluid. Otherwise, it will damage power steering system. Does anyone know that it is really requiring use only Honda power steering fluid or I can use other brand? May I just add more other brand power steering fluid (mix with fluid that already in the system)? Which brand/type of power steering fluid can I use? Thanks in advance!

 

Go to Autozone or Advance Discount - they both sell Honda ps fluid. Do what the manual says!

 

Thanks for the replied!
