Engine oil has four purposes: cleaning, cooling, lubrication and protection. In the cleaning process, the engine oil removes the contamination that can cause damage. Engine oil also cools the engine by absorbing heat, taking it away, and transferring the heat to the cooling system. Engine oil lubricates by introducing a thin, slippery film between metal parts, and it protects the engine with constituents that prevent corrosion of engine parts. It is essential to use the correct engine oil, and to replace the oil in a timely manner. Failure to do so can lead to severe wear of the engine components, and ultimately to engine failure.
The Cat Advanced Efficiency Engine Oil Filters (1R-18097 and 1R-1808) are new types of filters that ensure an even cleaner engine lubrication system. Both types incorporate improved filter media and design, so that particulate contamination is filtered out better than ever. What’s more, these filters have a superior dirt-retention capacity. The oil stays cleaner for longer, and the engine components are less subject to wear. Ultimately, the right moment to change the engine oil is determined by the condition of the oil, based on the lubricant analysis, rather than the filter capacity.
