OIL FILTER 3R0-07615-0

Function and technical context

The oil filter is the essential component of the lubrication system in 4-stroke petrol marine engines. Its main function is to retain dirt particles, worn metals and deposits that are generated during combustion, ensuring that only clean oil circulates to bearings, pistons and camshafts. Without efficient filtration, these impurities accelerate internal engine wear, reduce lubricant viscosity and compromise oil pressure. On boats, where the engines work at constant speed and under high thermal stress, maintaining the flow of filtered oil is critical to avoid mechanical failures at sea.

When to replace this part?

Oil filter replacement should be performed every 100 hours of engine operation or at least once per boating season, whichever comes first. Symptoms of a saturated filter include a drop in oil pressure indicated on the panel, increased lubricant consumption between changes, and visible soot buildup in the extracted oil. Replacing the filter preventatively at every maintenance is the most effective practice to extend engine life, avoid costly offshore repairs, and ensure optimal performance throughout the entire boating season.
