WIX Filtration 51791 Diesel Engine Oil Filter

The WIX Filters 51791 Diesel Engine Oil Filter is a spin-on diesel engine oil filter that removes contaminants from engine oil to protect lubrication systems in heavy-duty diesel equipment. Built with a heavy-duty metal canister housing and corrosion-resistant construction, it includes an anti-drainback valve and an integrated bypass valve to maintain oil flow during startup and under load. The filter uses a high-efficiency filtration media designed for high contaminant capacity and engine protection, and it comes with a gasket included for a proper seal. Flow is outside-in, and the unit is designed for engine oil use in diesel engines. It is commonly applied in commercial and industrial diesel engines across fleets, agricultural equipment, industrial machinery, construction equipment, and other heavy-duty diesel-powered systems requiring reliable filtration and continuous oil flow. The 51791 supports preventative maintenance and scheduled oil service, as part of routine engine protection and replacement of worn filtration components. Common replacements for this filter include Baldwin B7039, Donaldson P550520, and Fleetguard LF3313.
