Changes in Engine Lubrication: Prompts Changes in Filtration Technology

Today’s automotive engines have different filtration and lubrication requirements compared to engines produced in the past. Bearing clearances and the composition of the metal used in the bearings, plus changes in engine technology require different lubrication and filtration characteristics. Some assume that any viscosity oil will do and filtration efficiency s determined by the physical characteristics/dimensions of the filter alone. Filters of equal size often share different efficiency…
