Oils, lubricants and engine protection

Which oils to use to protect your boat's engine

Proper lubrication not only ensures optimal performance, but also extends the life of your engine. Discover our selection of engine oils, oils for bases and transmissions, steering and trim oils, as well as our marine greases and fuel additives.

The engine is the centerpiece of your boat, requiring rigorous and regular maintenance. Using the right oil is essential for the performance and longevity of your boat's engine. Choosing quality products is the best protection against corrosion and loss of engine sealing.

We offer a wide range of oils and greases for the maintenance of 2-stroke, 4-stroke, inboard, and diesel outboard engines, as well as shifters, bases, trims, and steering systems. Don't forget fuel additives, which will extend the life of your engine.

Without oil, your boat's engine would not be able to run and would quickly overheat. Oil acts as a lubricant for the components and reduces friction between the mechanical parts of your boat's engine. A good quality oil will also protect your engine from corrosion and improve its sealing. It is therefore important to choose the oil that is best suited to your boat's engine.

The differences between 2-stroke and 4-stroke engines

The choice between 2-stroke and 4-stroke oil is one of the points to which particular attention must be paid when choosing engine oil. The lubrication requirements for two-stroke and four-stroke engines are different.

In the case of 2-stroke engines, the oil lubricates the internal components of the engine by being burned in the combustion cycle, whereas in 4-stroke engines, the oil is continuously recycled.

Viscosity for 4-stroke engine oils:

Viscosity, or SAE grade, is something to keep in mind when choosing your motor oil. It is indicated in two ways: cold grade or dynamic viscosity and hot grade or kinematic viscosity.

The cold grade is an indication of the oil's fluidity when the engine is cold and its ability to adhere to the walls. The lower the index, the better the cold viscosity. A low index is therefore more recommended for winter.

The hot grade is an indication of the thickness of the oil film when the engine is hot. A low hot grade will be suitable for a slower, less frequently used engine, while high grades will be ideal for powerful, fast engines.

All types of oil

Mineral oils

Suitable for 4-stroke inboard engines. Derived from refined petroleum, these oils are suitable for engines without turbochargers. Mineral oils do not withstand high temperatures or high-speed engines well. They are recommended for older engines.

Semi-synthetic oils

As its name suggests, semi-synthetic oil is a blend of mineral oil and synthetic oil. It is of higher quality than mineral oil and is mainly used for recreational boats.

100% synthetic oils

Synthetic oils are very reliable and retain their properties for a long time. They are the highest quality oils on the market. They are mainly used for engines with high rotational speeds, primarily for the latest generation of engines.

When choosing your engine oil, it is best to refer to the manufacturer's recommendations. This will ensure that you get the right oil for your engine and that it meets your requirements.

Advice from PIECESBATEAUX.COM

Use the best oil for your boat's engine, base, and accessories: Volvo, Mercruiser, Suzuki, Johnson-Evinrude engines, etc.

To keep the engine clean and contain impurities related to fuel combustion, be sure to choose the right oil filter. Discover inboard engine oil filters, Mercury Mariner filters, Yamaha filters, and Suzuki filters.

Pièces Bateaux offers a wide range of oils and greases for maintaining engines, transoms, steering systems, and trims. You can also find fuel additives to extend the life of your engine.
