As you may know, Acura fluids are same as Honda but are labeled as Acura. Thus, their DW-1, VTM-4, Coolant, work just fine and are often less expensive than the same branded as Honda. We normally buy in bulk, dozens of boxes, with free shipping. If you know of other Honda or Acura owners, create a single large group buy for your workplace, gym, etc and you can often negotiate a better price. Bernardi just ran a special with free shipping on orders. Local dealers will often match an online price, especially if volume is more than a box of 12. Won't hurt to ask.
