Our number one goal in creating Yamalube is to ensure that you are getting the finest oil available for your Yamaha. Of course, no one oil is perfect for every application. That’s why Yamalube is available in the precise formula your Yamaha Engine needs.

The Yamalube Story
When Yamaha started making engines the engineers followed the common practice of recommending “off-the-shelf” oils. Experience began showing that conventional oils didn't always offer the level of protection against wear and tear the customer paid for. Unfortunately, that sometimes resulted in significantly shorter engine life. It became clear that our customers needed and deserved an exceptional oil product. The same engineering team began searching for lubricants that met Yamaha’s high standards. They insisted on the finest ingredients in precise formulations that would give dependable protection and enable the engine to deliver the high performance it was designed to give. This search eventually led to the development of our own premium oils – Yamalube.

What is Yamalube?
Each Yamalube oil is made from base oils, additives, and solvents in combinations specific for the application. For example, the additive package for Yamalube 2-M is outboard oil is very different from our Yamalube 2-R for motocross motorcycles, even though both are liquid-cooled 2-stroke engines. These two engine types have different stress loads, with the outboard often operating for extended periods under heavy load while the motocross engine is subjected to frequent bursts of throttle under extreme conditions. Consequently, the oils developed for these engines have different lubrication formulas.

Yamalube Base Oil comes in two forms, “neutral oil” and “bright stock”. Neutral Oil provides basic lubrication properties. It also acts as a “carrier” fluid,” one that carriers the additive package to the metal parts while carrying away carbon and varnish particles. Neutral oil can be mineral or synthetic in origin. Bright Stock is a thick oil that has anti-scuffing properties. It helps reduce piston scuffing. Yamalube uses carefully selected combinations of neutral oil and bright stock to match the needs of the application.

4-Stroke Marine 4-M FC-W® (SAE 10W-30) 4-M FC-W® (SAE 20W-40) Better for Your Yamaha Don’t trust your Yamaha to off-the-shelf substitutes. This is the oil designed for your four stroke Yamaha engine – precisely formulated to Yamaha’s uncompromising standards and extensively performance tested. Better Marine Protection The trend in marine power is moving to four stroke technology. Today’s four stroke outboards, sport boats and water vehicles deliver all the muscle, speed and performance of their two stroke counterparts. Though many of these engines are in the same displacement and power output range as high performance automobile engines, marine operating conditions are significantly more challenging. Four stroke marine engines are subjected to high loads and extended full-throttle operation, while operating in an environment that includes high humidity and salt air. In these severe conditions, premium lubricity is critical. Which is why the NMMA (National Marine Manufacturers Association) created the FC-W® rating, a performance standard specifically for oil used in four stroke marine engines. Yamalube 4-M is FC-W certified. Better Lubrication Yamalube 4-M surpasses Yamaha factory requirements, with a superior formulation: A higher level of bearing protection ... Superior rust and corrosion resistance ... Polymers that resist breaking down – even under the severe high load, high speed conditions common to outboards, water vehicles and sport boats ... More anti-wear additives than regular passenger car motor oils ... And the highest amount of detergents and dispersants, needed to keep your marine engine clean inside. Better Results The difference? Easier starts. Dependable protection, while enabling your engine to deliver high performance. Longer engine life. Everything’s better with Yamalube 4-M.
