The P558615 oil filter is a critical component in the lubrication system of FOTON trucks. Its primary function is to remove contaminants such as dirt, metal particles, and carbon deposits from the engine oil. Clean oil is essential for reducing friction, cooling engine parts, and preventing premature wear. The filter with part number P558615 is designed to meet or exceed the original equipment specifications, ensuring it can handle the specific flow rates and pressure of your FOTON engine. Regular replacement with a genuine P558615 filter is one of the simplest yet most effective forms of preventative maintenance.
This filter is often cross-referenced with other industry numbers like 3932217 and LF3349, indicating its wide compatibility and recognition. However, for guaranteed performance, always refer to the primary OEM number P558615 when ordering. The construction of this filter focuses on durability and filtration efficiency, using high-quality materials that withstand the harsh conditions inside an engine. For fleet managers and owner-operators, using the correct filter is non-negotiable for maintaining engine health and operational uptime.
High-Efficiency Filtration Media: The P558615 utilizes a pleated synthetic or cellulose media designed to capture a high percentage of contaminants as small as 20-40 microns. This ensures even the finest abrasive particles are removed from the oil circuit, protecting precision engine components.
Robust Construction & Anti-Drain Back Valve: The filter housing is made from durable steel to resist pressure and corrosion. An integrated anti-drain back valve keeps oil in the filter when the engine is off, preventing dry starts and ensuring immediate oil pressure upon ignition.
Consistent Oil Flow: Engineered to maintain optimal oil pressure, the P558615 filter provides consistent flow even as it loads with particles, thanks to its well-designed media surface area and bypass valve settings. This prevents oil starvation under any condition.
Engine oil is the lifeblood of your truck, but as it circulates, it picks up harmful contaminants from combustion, component wear, and the environment. The P558615 oil filter acts as the kidney of the engine, continuously cleaning this oil. Without an effective filter, these particles would act as abrasives, accelerating the wear of bearings, cylinder walls, and other critical parts.
A clogged or inefficient filter can also restrict oil flow, leading to increased pressure differential and potentially activating the bypass valve, which allows unfiltered oil to circulate. This defeats the purpose of an oil change. Therefore, using a high-capacity, efficient filter like the P558615 at every oil change is a direct investment in extending your engine’s service life and avoiding costly overhauls. It is a small component with a massive impact on total cost of ownership.
The oil filter bearing the OEM number P558615 is designed for a wide range of FOTON truck engines, particularly in the Auman and Aumark series. Its equivalency to numbers like 3932217 and LF3349 means it may also fit certain other commercial vehicle models, but the primary reference for FOTON owners should always be P558615 to ensure perfect fitment.
Before purchase, it is advisable to double-check your vehicle’s owner manual or consult with a parts specialist using your engine model or VIN. Using the correct filter ensures proper thread pitch, seal diameter, and pressure specifications. The P558615 is a common stock item at FOTON dealerships and reputable commercial vehicle parts suppliers, making it easily accessible for scheduled maintenance.
Replacing the oil filter is a standard maintenance procedure. For the P558615, ensure you have the correct tools: an oil filter wrench, a drain pan, and new engine oil. Always perform an oil change when the engine is warm but not hot, to allow impurities to be suspended in the oil and drain effectively.
Installation Steps:
1. Safely elevate the truck and place the drain pan under the oil pan and filter.
2. Drain the old engine oil completely.
3. Use the filter wrench to loosen and remove the old filter. Ensure the old gasket comes off with it.
4. Wipe clean the filter mounting surface on the engine block.
5. Apply a thin film of new engine oil to the rubber gasket of the new P558615 filter.
The service life of the P558615 oil filter is directly tied to your truck’s oil change interval. For FOTON trucks, this interval can vary based on the engine model, type of service (severe vs. normal duty), and the oil used. Typical intervals range from 10,000 to 25,000 kilometers.
It is imperative to replace the P558615 filter at every oil change without exception. Even if the oil is changed, reusing an old filter contaminates the new oil immediately with the sludge and particles trapped in the old filter. Adhering to the manufacturer’s recommended service schedule using genuine P558615 filters is the best strategy for engine longevity.
For vehicles operating in severe conditions—such as frequent short trips, extreme temperatures, dusty environments, or heavy towing—more frequent oil and filter changes (using P558615) are strongly recommended. Keeping a log of maintenance with part numbers used is good practice for resale value and warranty purposes.
