XD30 and XD50 are oils sold by BRP for Evinrude and Johnson two stroke motors.

XD50 has a built-in carbon treatment so you don't need to pay extra for a carbon preventative additive if you use the XD50.

TC-W3 is a national rating for oils that are for Two Cycle-Water Cooled outboard engines: http://www.nmma.org/certification/programs/oils/

TC-W3 is a minimum standard; most long term users prefer synthetic or synthetic blend TC-W3 oils.

So I would be okay using either the XD-30 or XD50?
