Boat Engine Maintenance: Change Oil & Filter

best marine motor oil Main tip to keeping your boat engine running the best is to do an Oil check/change
Let us begin with the self-evident: Check your motor oil frequently and replace it according to the manufacturer’s recommendations. This is the very first step in any boat engine maintenance program.

Engine oil is your engine’s only line of defense against breakdowns and decreased performance caused by wear and deposits.

Oil changes prior to storage are critical for optimal boat engine maintenance. This method eliminates acidic combustion byproducts and ensures that fresh oil is available to protect components from corrosion during storage. Do not forget to replace the oil filter as well.

Utilize a marine-specific engine oil.

Contrary to popular belief, motor oil does not contain any natural anti-rust or anti-corrosion properties. Rather than that, special rust and corrosion inhibitors must be added to the formulation to provide the necessary protection, and some oils simply lack the necessary additives in the required concentrations.

Protection against rust and corrosion is critical given your engine’s exposure to water.

When the engine is switched off, certain valves remain partially open, allowing damp air to enter the combustion chamber. Rust and corrosion begin to form, releasing contaminants into the oil, where they act like sandpaper, scouring metal surfaces until engine failure occurs.

To avoid this scenario, use an oil specifically formulated for marine engines, such as AMSOIL Synthetic Marine Engine Oil.

Maintain your boat engine with the best products. Here are a few AMSOIL products that that you can use in your boat engine
