NAPA auto parts in Burnsville carries Amsoil. Im not sure all napas carry it. The 2 cycle for the boat was $10 a gal cheaper at napa compared to FF with a company discount. I bought my last qt for lower unit at FF
Nelson: go to amsoil.com and there is a link to the dealer locator. Type in the zip code and see if it’s convenient. I found a few in St. Paul where you could call.
I’ve also found amsoil at some of the smallest ma & pa auto parts stores (like my local NAPA) and it doesn’t show up on the dealer locator.
