TC-W3

— the TC-W3 standard applies to engine oils for water-cooled 2-stroke outboard engines. This standard was introduced in 1992, it noticeably replaced the TC-W2 series of oils. A key feature of the lubricant is the complete absence of ash compounds. The clean base of the oil has a positive effect on the reliability and durability of the rubbing pairs of the engine, in particular, the coking of piston rings is minimized. TC-W3 engine oils are used in modern outboard motors mainly from the middle price segment.
