Honda owners ask me this constantly: does it have to be the Honda-branded DW-1 from the dealer, or can I buy it on Amazon and get the same thing? It's a fair question, and the answer is more straightforward than most forums make it. Honda DW-1 is a proprietary fluid specification. Honda licenses the production of DW-1 to a small number of manufacturers — the fluid that comes in the white Honda bottle from the dealer is the same formulation as the Honda-branded DW-1 you can buy on Amazon. It is not a different product. The Honda part number is 08200-9008 (quart) and 08200-9008L (gallon). Whether you buy that bottle from a Honda dealer parts counter or from an Amazon seller shipping Honda OEM fluid, you are getting the identical product. The only difference is price and shipping convenience.
