Our take on the Mercury Marine 8M0188359 SAE 25W-40 4-Stroke Outboard Oil Change Kit for L6 200-400hp Verado Outboards

This is Mercury's own oil change kit for the 6-cylinder Verado outboards from 200 to 400 hp. It bundles seven 1-liter bottles of Mercury SAE 25W-40 four-stroke marine oil with the correct premium filter, a drain plug seal, a drip tray and instructions, so one box covers a full service. The oil carries a marine-specific additive package with corrosion inhibitors for storage and viscosity retention under high-rpm, high-heat running. Buying the factory kit removes the guesswork of matching filter and oil grade; generic 25W-40 and aftermarket filters can work, but this is the combination Mercury specifies for the Verado.
