Fits: 2001-2019 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ/LMM/ LML/L5P 

This kit comes with everything that you need to change your 6.6l Duramax's engine oil in one convenient package. With some of the highest quality oils on the market the Amsoil products are made to exceed the OEM standards providing superior wear protection. 

Includes:

• 2.5 Gallons of Amsoil Signature Series Max-Duty Synthetic 15W-40 Diesel Oil (May be shipped in 2.5 gallon jug or 10 quarts)
• Amsoil EA052 Oil Filter

Optional items:

• Oil Drain Plug Gasket
  • ​It is recommended to replace after each oil change as it is a one time use gasket and will help prevent damage to the oil pan and prevent leaking.
• PPE Magnetic Drain Plug
• Standard Drain Plug
• Fumoto N-Series Oil Drain Valve
• *Discounted* DmaxStore Billet Aluminum Oil Fill Cap (2001-2016 ONLY)

Amsoil Max Duty Oil Features:

• Maximum engine protection
• Viscosity control
• Excels in extreme temperatures
• Minimizes oil consumption

Wear on rings and cylinder liners leads to increased oil consumption and loss of compression, resulting in reduced horsepower and fuel economy. Independent testing shows AMSOIL Signature Series Max-Duty delivers 6X more wear protection*, delivering the security of providing your diesel the extra protection it deserves.

*Based on independent testing in the Detroit Diesel DD13 Scuffing Test for specification DFS 93K222 using a 5W-30 as worst-case representation.

Using top-tier synthetic base oils, AMSOIL Signature Series Max-Duty is naturally resistant to oxidation and the thickening effects of soot contamination. That, along with boosted detergent/dispersant additives, keeps soot particles suspended independently, helping prevent the formation of larger, wear-causing particles. Viscosity increase is minimized and soot-related wear is controlled. Lower volatility also helps Signature Series Max-Duty retain its viscosity after high-temperature service for maximum engine protection and efficiency.

AMSOIL Signature Series Max-Duty Synthetic Diesel Oil resists thermal (heat) breakdown better than conventional and competing synthetic diesel oils. Unlike conventional oils, Signature Series contains no wax, staying fluid in sub-zero temperatures for easier starting, improved oil flow and reduced wear.

AMSOIL Signature Series Max-Duty has a low rate of volatility (burn-off), reducing oil consumption during operation and passing less oil vapor into the combustion chamber. It provides up to 76 percent less oil consumption than required by the API CK-4 standard in the Caterpillar-1N oil consumption test.​​

Amsoil EA Oil Filter Features:

• Absolute Efficiency
• Less restriction
• Contaminant retention
• Superior construction

AMSOIL Ea® Oil Filters (EaO, Ea15K) have one of the best efficiency ratings in the automotive/light-truck market. Ea Oil Filters provide a filtering efficiency in accordance with industry standard ISO 4548-12 of 98.7 percent at 20 microns, while competitive filters demonstrate efficiencies as low as 51 percent.

AMSOIL Ea Oil Filters have lower restriction than conventional cellulose media filters. Their small synthetic fibers trap smaller particles and hold more contaminants, resulting in lower restriction. During cold-temperature warm-up periods, an Ea Oil Filter allows the oil to flow through the filter more easily than a typical cellulose filter does. Lower restriction decreases engine wear.

A filter’s capacity refers to the amount of contaminants it can hold and still remain effective. AMSOIL Ea Oil Filters have a greater capacity for small, wear-causing contaminants than competing filter lines. In fact, when used in conjunction with AMSOIL synthetic motor oils, AMSOIL Ea Oil Filters are guaranteed for up to 15,000 miles/one year, whichever comes first, or 25,000 miles/one year, whichever comes first, depending on application and severity of service.

AMSOIL Ea Oil Filters are made with premium-grade full-synthetic media. The strictly controlled processing of this media ensures accurate filter construction and is what allows Ea Oil Filters to deliver higher capacity and efficiency along with better durability.

Over the service life of a conventional cellulose filter, hot oil will degrade the resins that bind the media. Ea Oil Filters’ full-synthetic media technology is resin-free. It uses a wire screen backing that is pleated with the media for superior strength.

Ea Oil Filters are constructed with HNBR gaskets that are fully tested to extreme distances in numerous severe environments. The filters also feature fully tucked seams, a molded element seal, roll-formed threads and a long-lasting, premium grade silicone anti-drain valve. They also feature fluted cans for improved grip.
