Yamaha Marine Group announced it has a new four-stroke (4M) marine engine oil formulation, which reduces wear and provides cleaner operation.

Yamalube 4M engine oils, both 10W-30 and 20W-40, have a new low-phosphorus formulation that is fortified with molybdenum compounds, which greatly reduce wear caused by the sudden changes in engine speed common to four-stroke marine engines.

Independent testing shows the new oil provides added wear protection -- an 85 percent reduction in wear over the prior formulation. These oils have properties and additives automotive oils do not have. In addition, they continue to contain a proprietary mixture of detergents, which help clean internally lubricated parts, and dispersants, which help to carry trapped dirt away from the engine to the oil filter. The end result is cleaner oil.

With the change comes color-coded packaging designed to improve the customer's ability to choose the correct product for the job at hand. For example, Yamalube 4M will include an image of a four-stoke outboard on the label, while Yamlube 2M (two-stroke oil) will include an image of a two-stoke outboard.

Yamaha is creating and launching an extensive campaign for dealers and customers as part of the rollout, including easily-identifiable in-store display materials.
