The oil filter on a Chevrolet S-10 pickup is located on the underside of the engine block and filters small particles out of the engine oil. Because of the tight tolerances in modern automotive engines, relatively small particles can cause serious damage to valve train and/or crankshaft bearings if allowed to circulate freely within the oil system. In years past it was advised to change the oil filter with every other oil change; but because oil filters are relatively inexpensive, they are normally replaced at every oil change.
