Mobil M1-405A Extended Performance Oil Filter — 20,000-Mile Protection, Synthetic-Blend Media

The Mobil 1 M1-405A Extended Performance Oil Filter delivers up to 20,000 miles or one year of filtration with high-efficiency media and heavy-duty construction.

Designed for motorists who want extended service intervals without compromising engine cleanliness, this Mobil 1 filter combines synthetic-blend filter media, reinforced canister materials, and thoughtful sealing features. It’s engineered to remove the vast majority of airborne and combustion-generated particles while maintaining oil flow and protecting against dry starts. The result is longer-lasting oil performance and a filter built to withstand tougher operating pressures than conventional economy units.

How does the M1-405A keep my oil cleaner for longer?

The filter uses a high-efficiency synthetic-blend media that captures very small particles and holds more contaminants than standard paper filters. That helps retain oil cleanliness over extended intervals and reduces particle circulation in the engine.

• Synthetic-blend media removes over 99% of harmful contaminants.
• Higher dirt-holding capacity extends effective filtration life.
• Engineered pleat structure maintains flow while trapping debris.

What construction features protect the engine and prevent leaks?

Mobil 1 builds the M1-405A with durable materials to resist pressure and maintain a reliable seal during long service intervals. The gasket and anti-drainback systems minimize oil loss and help avoid dry starts, while the robust canister handles tougher pressure conditions.

• Enhanced nitrile gasket remains pliable to reduce leak risk.
• Durable anti-drain back valve prevents oil from draining out between starts.
• Heavy-duty canister withstands up to nine times normal oil system pressure.

Can I really go up to 20,000 miles or one year between changes?

The M1-405A is engineered and tested to support extended protection when used with compatible Mobil 1 oils and following vehicle manufacturer recommendations. It’s backed by Mobil’s extended protection standards, but actual service intervals depend on driving conditions and vehicle requirements.

• Rated to protect for up to 20,000 miles or one year under appropriate conditions.
• Tested to offer protection twice as long as typical manufacturer oil change intervals.
• Refer to your owner’s manual and driving conditions to set intervals.

How does this filter compare to economy alternatives?

Compared with basic filters, the M1-405A uses upgraded filtration media and a reinforced canister to provide higher contaminant retention and greater mechanical durability. Those differences aim to support longer service life and improved protection for modern engines.

• Synthetic-blend media captures finer particles than economy paper filters.
• Stronger canister construction resists deformation and pressure-related failure.
• Enhanced sealing parts reduce the chance of leakage and oil loss.

Who is this for: The Mobil 1 M1-405A Extended Performance Oil Filter is suited to drivers who prefer extended oil change intervals, owners of vehicles compatible with Mobil 1 filters and oils, and anyone seeking a higher-capacity filter with reinforced mechanical components. It’s a practical choice for commuters, long-distance drivers, and performance-minded motorists who want robust filtration and durable construction without frequent service.
