Or Just use the Acura Fluid, it's what's called for, the price won't be much different between the two of them there is conflicting info on whether they are the same part, frequently Honda and Acura parts numbers are identical just the Acura part has an A on the end, but it appears the fluids may be different, why does Honda have to be so difficult and make different Honda and Acura part numbers, you buy any of the Ford badges it'll tell you to use genuine Motocraft yadda yadda, you buy anything GM, it'll tell you to use AC Delco yadda yadd, but you buy a Honda or Acura and they tell you to use only Honda or only Acura fluids in their respective manuals.
