Motor Oil and Marine Grease

Marine engine oil is essential for the longevity and efficiency of your boat engine. Unlike automotive oils, nautical engine oils are formulated to withstand the corrosive marine environment and the stresses typical of boating. Poor quality oil can cause premature wear, overheating, and, in the worst cases, irreparable engine damage.

We stock specific oils for 2-stroke engines (often used on small outboards) and 4-stroke engines (found on most boats). We also carry ATF oils for hydraulic gearboxes and specific lubricants for steering systems, which are essential for smooth and precise handling.

Choosing the right oil means protecting your investment and ensuring safe boating.

The Nautica Basile Tip

• Visual Check: Regularly check the oil level with the dipstick. A low level indicates a potential leak or excessive consumption.


• Oil Change: Strictly follow the manufacturer's instructions for oil change frequency. Typically, an annual oil change or every 100 hours of operation is recommended.


• Gearbox Oil: The hydraulic gearbox oil should be checked and replaced periodically to prevent slippage and malfunctions.


• Extra Lubrication: Use specific marine grease to protect engine components exposed to salt water, such as bearings and bushings.

Don't neglect your engine's maintenance! Regular checks and the use of quality lubricants will guarantee years of trouble-free boating.

FAQ - Frequently Asked Questions

What type of oil should I use for my 2-stroke outboard engine?

For 2-stroke outboard engines, use a specific 2-stroke marine engine oil with TC-W3 classification. This type of oil is formulated to mix properly with gasoline and protect the engine from corrosion and wear in the marine environment.

How often should I change the oil in my diesel inboard engine?

The oil change frequency for diesel inboard engines varies depending on the model and operating conditions. In general, it is recommended to change the oil every 100-200 hours of operation or at least once a year, following the engine manual's instructions. Always use engine oil with API CF or higher specifications.

Can I use the same oil for the engine and the hydraulic gearbox?

No, engine oil and hydraulic gearbox oil are different and not interchangeable. The hydraulic gearbox requires a specific oil, usually an ATF (Automatic Transmission Fluid), which ensures proper lubrication and operation of the transmission system. Consult your gearbox manual for the exact specifications.
