Yamalube oils offer unrivaled quality and ensure that your engine remains in excellent condition throughout its lifespan. However, when it comes to comparing two Yamalube oils, like Yamalube 2M oil and Yamalube 2W oil, it’s not so easy to make a distinction. When selecting a Yamalube oil for your engine, first consider the kind of engine you have, and how you will be using it. For example, the Yamalube 2W oil contains large amounts of metallic additives, which is necessary for the constantly changing RPMs on a personal watercraft. Yamalube 2M is more designed for outboard motors, and is intended for use in extreme engine conditions, such as rapid acceleration in sports boats, or trolling on fishing boats.
Different formulations of outboard motor oil are intended to be used during different engine conditions. It’s also wise to check with the manufacturer of your engine and ensure that the kind of oil you are using will not void its warranty.
