What is the most suitable oil for a marine engine?

Doubts usually arise about which oil is the most suitable for a marine engine and, therefore, one of the most frequent consultations with Solé Diesel's technical service is precisely to know what oil to put in a boat engine and in marine transmissions.

If you want to know what type of oil is best for your boat's engine and how it can extend the life of your propulsion and generation equipment, below you will find tips to help you with your regular maintenance.

For marine engines, marine generator sets and hydraulic gearboxes, we recommend always putting multigrade oil specially designed for this type of machine.

15W40 Multigrade Solé Diesel oil, “ACEA E5 / E3. API CH-4 / SJ”-certified is specially developed to lubricate the engine even under harsh conditions with high loads and high temperatures. It also acts as a great corrosion protector and keeps the engine interior clean, resulting in less wear and therefore greater durability.

If you have ever wondered if it is possible to use the same oil in the engine of the boat as in the car, keep in mind therefore that it is not recommended since the properties of both types of oils are different, with specific viscosities and additives, developed to work and protect the engine in different conditions and environments.

For mechanical gearboxes, we recommend you instead always use ATF oil.

ATF Solé Diesel oil helps reduce marks and friction normally produced in mechanical transmissions. Thanks to its components and special additives, this oil offers high wear resistant power and allows an impeccable transmission of power from the engine to the propulsive line. Using this oil in your mechanical gearbox will help you optimize its performance.

Remember that good lubrication is key to getting the best performance and extending the life of the engine or generator. Always consult the user manual before performing any maintenance and rely only on professionals authorized by the manufacturer.
