Over time, engines during their operation can have various effects on oil. These include deposition, contamination, increased viscosity, and a decrease in oil quantity. These occurrences can lead to issues such as ring sticking, corrosion, wear, and more. Therefore, the importance of choosing high-quality oil is doubled Standard organizations have not defined a specific standard for marine engine oils. Requested tests are conducted on specific cases, and there is no specific standard. The absence of a standard is a significant factor due to the high test duration required for these engines, which is at least 5,000 hours, equivalent to about a year PetroForce provides specialized formulations for marine oils that significantly contribute to improving the marine engine system
