Royal Purple Extended Life Oil Filters & Synthetic Motor Oils


Superior particle removal, high-performance and optimized flow characteristics for maximum performance and longer filter life.

Royal Purple Extended Life Oil Filters

Royal Purple’s filter media uses the latest technology filtration system that filters out particles as small as 25 microns.

Conventional Fiber

Conventional cellulose filtration fibers magnified 250x.
The spaces allow larger particles to pass through to your engine.


Royal Purple Better Oil Filter Fiber


Royal Purple’s oil filter filters out particles as small as 25 microns.


  • Filter Element: 100% screen-backed synthetic media provides superior filtration while keeping flow restriction low.
  • Shell: Thicker shell material for extra strength. The heavier shell provides extra security against puncture from road debris and endures higher burst strength than conventional filters.
  • Steel Backplate: Heavy gauge steel for higher burst strength.
  • Metal End-Caps: Provides positive seal for filter element assembly.
  • Center Tube: Prevents filter element collapse
  • By-Pass Valve: The by-pass valve is designed to insure oil flow in situations of excessive filter element flow restriction.
  • Gasket: Premium nitrile rubber with special lubricity compound to reduce torque during installation and removal  and to ensures a leak-free seal.
  • Silicone Anti-drain Back Valve: Prevents dry starts by eliminating oil drain back during shutdown through the use of a silicone anti-drain back valve. Silicone outperforms and outlasts standard nitrile rubber in both extreme cold and hot oil temperatures. A high-performance silicone anti-drain back valve that prevents dry starts, even in extreme conditions.

Synthetic Motor Oil

Royal Purple Motor Oil delivers superior protection and improves performance in four-cycle gasoline and diesel engines.

It increases horsepower and torque, saves fuels and reduces heat, wear and emissions. It has unsurpassed oxidation stability that allows for extended oil drains and fewer oil changes, which saves you time and money and reduces the impact on the environment.

Royal Purple’s performance advantages come from a blend of synthetic oils plus Royal Purple’s proprietary Synerlec technology. Royal Purple Motor Oil is compatible with other mineral and synthetic motor oils.
