The ECOGARD X5526 Engine Oil Filter is engineered to provide superior filtration for Ford Super Duty diesel engines, including the F-250 and F-350 models equipped with 6.0L and 6.4L engines from 2003 to 2010. This filter is designed to effectively remove contaminants from engine oil, ensuring optimal engine performance and longevity. Its high-efficiency cellulose media captures 97% of particles as small as 30 microns, safeguarding critical engine components from abrasive wear. The filter's robust construction features a one-piece spiral wound, corrugated center tube that enhances collapse strength, and a heavy-duty filter body capable of withstanding five times the normal oil pressure. Additionally, the molded nitrile anti-drain back valve prevents dry starts by retaining oil within the filter when the engine is off, while the pressure relief valve ensures continuous engine lubrication under all operating conditions. The ECOGARD X5526 is compatible with both synthetic and conventional oils, allowing for oil change intervals up to 5,000 miles, thereby reducing maintenance frequency and associated downtime. This filter meets or exceeds OEM specifications, providing a reliable and cost-effective solution for fleet operators seeking to maintain engine health and performance.
