This is Mercury's own oil change kit for its 3.4L V6 and 4.6L V8 four-stroke outboards rated 175 to 300hp. It bundles seven 1-liter bottles of Mercury SAE 10W-30 marine oil, a Mercury oil filter, a drain hose and instructions, so one box covers a full service. The oil carries a marine-specific additive package with corrosion inhibitors for storage and high-temperature, high-rpm running, and it is blended to Mercury's OEM spec. It suits owners who service their own engine and want factory-matched parts; buyers running other brands or smaller four-strokes should check their spec first, since the kit is sized and filtered for these Mercury V6 and V8 blocks only.

Owners of Mercury V6 and V8 four-strokes generally rate the kit as a convenient, factory-correct service pack, with the included drain hose and exact-fit filter singled out. Complaints center on it being locked to one engine family and on the cost of buying the filter and hose bundled every time.
