What This Kit is Used For
This Mercury oil change kit provides the routine maintenance parts needed to perform an engine oil and oil filter service on compatible Mercury V6 and V8 FourStroke outboards.
Mercury SAE 10W30 Synthetic Blend marine engine oil is formulated specifically for marine environments and includes advanced corrosion inhibitors designed to help protect internal engine components during operation and storage.
The synthetic blend formulation helps maintain lubricity and viscosity retention during high-temperature operation and demanding RPM ranges common in modern high-horsepower marine engines.
Regular oil and filter maintenance helps support proper lubrication, reduce internal engine wear, and maintain long-term engine reliability.
