Royal Purple 20-561 Extended Life Premium Engine Oil

Royal Purple manufactures only one type of oil filter – the super-premium Extended Life Oil Filter, designed and engineered to match superior particle removal with optimized flow for maximum engine protection and filter life. Built smarter and stronger, Royal Purple synthetic oil filters continuously outperform in the toughest conditions.

The 100% synthetic micro-glass media we use to make Extended Life filters provides superior particle removal – with 99% filtration efficiency at as small as 25 microns.

Each Royal Purple oil filter features thicker shell material for extra strength and extra security against puncture from road debris. Metal end caps provide each oil filter with a positive seal for filter element assembly. The center tube is designed to prevent filter element collapse.

A 100% screen-backed synthetic media provides superior filtration while keeping flow restriction low. The by-pass valve is engineered to ensure oil flow in situations of excessive filter element flow restriction. A heavy-gauge steel backplate provides each filter with higher burst strength. The gasket made of premium nitrile rubber with special lubricity compound reduces torque during installation and removal.

Finally, the silicone anti-drain back valve prevents dry starts by eliminating oil drain-back during shutdown. The anti-drain back valve is made of silicone, which outperforms and outlasts standard nitrile rubber in both extreme cold and hot oil temperatures.

Magnified 250 times, a microscope shows large spaces in conventional cellulose filtration fibers. The spaces allow larger particles to enter the oil stream and infiltrate the engine.

Royal Purple's filter media uses the latest technology filtration system to catch particles as small as 25 microns.

Royal Purple Oil Filter features 100 percentage synthetic micro-glass media for superior particle removal with 99 percentage filtration efficiency at 25 microns. This product is designed with a high-performance silicone anti-drain back valve that prevents dry starts, even in extreme conditions and an extra heavy-duty rubber base gasket that ensures a leak-free seal. The Royal Purple Oil Filter also provides an ultra-strength filter housing that can endure higher burst strength than conventional filters. Royal Purple filters are fully compatible with all synthetic and conventional oils, provide superior particle removal, high-performance, optimized flow characteristics for maximum performance, and longer filter life.
