How does the M1C-259A filter keep oil cleaner for longer?

The filter uses a high-efficiency synthetic blend media designed to capture the vast majority of damaging particles in circulating oil. That media targets contaminants across a range of sizes to help preserve oil quality between service intervals.

• Removes over 99% of harmful contaminants from the oil stream.
• Media engineered for extended flow and particle-holding capacity.
• Compatible with synthetic and conventional engine oils.

What strength and leak protection features does this filter offer?

Mobil 1 built the filter with a heavy-duty canister and robust sealing components to withstand higher-than-normal pressures and reduce leak risk. The design helps protect against common failure modes that can occur during long service intervals or under elevated operating conditions.

• Canister construction rated to withstand up to nine times normal oil system pressure.
• Enhanced nitrile gasket improves seal durability to resist leaks.
• Anti-drain-back valve reduces oil loss and helps prevent dry starts after shutdown.

Can this filter really support extended service intervals?

When installed and used according to manufacturer guidance, the M1C-259A is tested to provide protection for up to 25,000 miles or one year. The combination of high-efficiency media and rugged construction is intended specifically for extended intervals, though following vehicle manufacturer service recommendations remains important.

• Tested performance up to 25,000 miles or one year when used as directed.
• Warranty-backed for added confidence—see Mobil 1 warranty details.
• Suitable for vehicles that allow extended intervals and use compatible oil types.

How do I choose this filter for my vehicle?

Select the M1C-259A if it matches your vehicle’s OEM filter part number or cross-reference listings for fitment. Ensure your vehicle’s maintenance plan and oil type support extended intervals before relying on long-duration service schedules.

• Check compatibility with vehicle fitment guides or OEM part references.
