I was reading the manual for my honda accord today and I noticed I says to use only Honda, well, pretty much everything except wiper fluid. It said if I were to use anything other than Honda engine coolant, power steering fluid, brake/clutch fluid, etc that these could cause corrosion and or damage. Is this true or is it just BS to get people to buy their OEM fluids? Has anyone here experienced problems using aftermarket fluids over OEM in a honda accord?
