                    If you need to purchase a smaller volume of msrine motor oil this is a good choice and competively priced. West Marine has a good selection of weights to cover both duty and seasonal requirements.

                      Seems to work fine - I don't see any reason to spend the "long dollar" on the more expensive brands
