Comments about Mercury Marine Mercury Marine 25W-40 4 Cycle Motor Oil:
Mercury Marine 25W-40 4 Cycle Motor Oil is recommended by manufacturers. This product is durable and protects all season long. I have never had an internal part failure using this oil in over 500 hours of service in my 2000 Rinker Captiva 212 w/ 5.7 Magnum power.
