Why 25 40 Marine Oil is Necessary
I have been an avid boater for many years and have learned the importance of using the right marine oil for my boat’s engine. In particular, I always make sure to use 25 40 marine oil for several reasons.
Firstly, marine engines are subject to harsher conditions compared to regular car engines. They are constantly exposed to saltwater, which can cause corrosion and buildup in the engine if not properly lubricated. 25 40 marine oil is specifically designed to withstand these harsh conditions and provide superior protection for the engine.
Moreover, marine engines tend to run at higher RPMs compared to car engines. This means that they require a higher viscosity oil to maintain proper lubrication and prevent friction between moving parts. 25 40 marine oil has a higher viscosity compared to regular car oil, making it more suitable for marine engines.
Another important factor is the temperature at which the boat operates. Marine engines are often used in open waters where the temperature can fluctuate greatly. This can cause regular car oil to thin out or thicken, affecting its ability to protect the engine. However, 25 40 marine oil has a wider temperature range and maintains its viscosity even in extreme temperatures
