The Fleetguard Oil Filter is designed to keep your engine running at its peak performance. It is designed to withstand the demands of time and extreme temperatures without failing or bypassing. It features a built-in bypass valve to ensure continuous oil flow during cold starts or in case of filter blockage. The spin-on lube filter protects the engine from wear particles, extending oil life and intervals between oil changes. It also contains an anti-drainback valve, by-pass valve and front end by-pass valve for added protection. FleetPride is your First Click in Heavy Duty®.
