Re: quick silver 2 cycl oil ok to use in stead of evinrude tcw3
There are 2 grades of Quicksilver (Mercury) oil,
Premium and Premium PLUS. Be sure you use the PLUS oil as the regular Premium used to say it was for engines below 75hp.
The Premium PLUS is the equivalent to the Evinrude and Yamaha factory oils as it has more anti-wear additives than the cheaper version.
