A spin-on oil filter can be mounted in an easily accessible position on an engine by means of an oil filter housing comprising a lower housing unit (4) , which comprises an open-topped chamber, and an upper housing unit (6) . A ma le threaded portion, adapted to mount a spin-on oil filter, extends up from the bottom surface of the lower housing unit. A flat gasket sealing surface is located on the bottom surface, wherein the gasket surface is perpendicular with the male threaded portion. The housing ocmprises three passages: (i) a first passage adapted to permit flow of dirty oil to an oil filter mounted o n the male threaded portion,- (ii) a second passage adapted to permit flow of filtered oil away from an oil filter mounted on the male threaded portion; and, (iii) a third passage adapted to permit drainage of oil from the open- topped chamber. The upper housing unit (6) is removably attached to the lowe r housing unit (4) , and is adapted to cover the opened- topped chamber. Metho ds of maintaining the filter and of adding refill oil are facilitated by this housing.
