Products Filters > Oil Filters
The function of oil filters is to prevent contaminants which may be contained in the lubricating oil from reaching sensitive engine parts without restricting normal oil flow. The internal source of contamination include wear products from the rubbing surfaces on engine, blow-by gases leaking from the rings of pistons and de-gradation of oil itself. Having your oil and oil filter changed, at least as often as recommended by the manufacturer, is likely to generate the single biggest return on your routine-maintenance investment. Replacing the dirty oil filter with an ACDelco oil filter will help protect the internal parts of the engine from premature wear & tear.
