Ultimate Engine Protection: 1000-4246-55A Sinotruk Oil Filter – Superior Filtration for Nigerian Howo Trucks
The Sinotruk Oil Filter 1000-4246-55A is a high‑efficiency spin‑on filtration component designed for Weichai, Sinotruk, and Cummins engines in HOWO, Sinotruk, and STEYR heavy trucks operating across Nigeria.
This genuine OEM filter, identified by the part number 1000-4246-55A, is manufactured from high‑grade pleated paper media with a metal center tube and nitrile rubber anti‑drainback valve, providing exceptional dirt‑holding capacity and filtration efficiency.
Trust this component to remove abrasive contaminants, extend engine life, and keep your fleet running reliably under Nigeria’s most punishing conditions.
Engineered for Nigeria’s Harsh Lubrication Environments
The genuine Sinotruk oil filter (OEM 1000-4246-55A) is a critical component that removes abrasive dust, soot, and wear metals from engine oil on HOWO, Sinotruk, and STEYR heavy trucks.
With over 50,000 Sinotruk trucks operating across Nigeria, reliable oil filtration is essential for preventing premature engine wear, reducing oil contamination, and maintaining power output.
This filter is manufactured from high‑grade pleated synthetic or cellulose media with a metal center tube and a nitrile rubber anti‑drainback valve, offering high dust-holding capacity and 98% filtration efficiency at 20 microns.
For Nigerian fleets battling bearing wear, turbocharger damage, or sludge buildup due to poor filtration, the 1000-4246-55A oil filter provides a durable, factory‑fit solution that restores engine protection and extends overhaul intervals.
By choosing the authentic filter, you eliminate contaminant circulation, reduce engine wear, and lower oil consumption.
Each unit is factory‑tested for efficiency, flow restriction, and burst strength.
Nigerian fleet owners report longer engine life, reduced turbocharger failures, and extended oil change intervals after installing genuine 1000-4246-55A filters.
This is a direct replacement for the original component, saving workshop hours and restoring factory oil filtration protection.

Nigeria’s roads are often unpaved, kicking up clouds of laterite dust that contains highly abrasive silica particles.
These particles, if ingested into the engine through the crankcase ventilation or from contaminated oil, cause rapid wear of piston rings, cylinder liners, and turbocharger bearings.
The Sinotruk 1000-4246-55A oil filter is specifically engineered to capture these contaminants.
Its multi‑layer pleated media offers 98% efficiency at 20 microns, ensuring that only clean oil reaches critical engine components.
The filter’s high dirt-holding capacity (up to 25 grams depending on conditions) allows for extended service intervals, reducing maintenance costs.
For fleet managers in Lagos, Kano, and Port Harcourt, installing a genuine 1000-4246-55A oil filter translates to lower engine wear, reduced oil consumption, and fewer turbocharger failures.
A clogged or low‑quality filter can restrict oil flow, causing bearing starvation and catastrophic engine failure.
The 1000-4246-55A eliminates these risks, providing a reliable filtration solution that keeps your engine lubricated with clean oil.
Moreover, this oil filter is fully compatible with Sinotruk HOWO, A7, and STEYR engines (Weichai WD615, WD618, WP10, WP12, WP13, and MC series).
It directly replaces the original filter without modifications.
When you combine this filter with other genuine HOWO Parts — HOWO Parts — you ensure a complete, reliable lubrication system that maximizes engine life and performance.
The synergy of genuine components eliminates contaminant bypass, reduces sludge formation, and extends the life of the engine oil.
High‑Efficiency Media & Robust Construction
Each 1000-4246-55A oil filter is manufactured using high‑grade pleated paper or synthetic media with a water‑resistant resin treatment.
The media is pleated to maximize surface area, reducing oil flow restriction while increasing dirt-holding capacity.
The filter is assembled with a metal center tube and a nitrile rubber anti‑drainback valve that prevents oil from draining back into the pan when the engine is off, ensuring immediate lubrication on startup.
A bypass valve (cracking pressure 2.0–2.5 bar) allows oil to bypass a clogged filter to prevent starvation.
For high‑mileage fleets, this means reliable service for the full recommended change interval (typically 30,000–50,000 km with synthetic oil).
A counterfeit filter may use low‑grade paper that tears, have inadequate pleat density, or lack a proper anti‑drainback valve, allowing dry starts.
The genuine 1000-4246-55A eliminates these risks, providing a precision‑engineered filter that restores factory oil filtration protection and durability.

Installation Best Practices for Nigerian Workshops
To ensure optimal engine protection, follow these professional guidelines when installing the 1000-4246-55A oil filter.
Drain the old oil while warm to suspend contaminants.
Clean the filter mounting surface thoroughly.
Apply a thin film of clean engine oil to the new filter’s rubber gasket.
Hand‑tighten the filter until the gasket contacts the base, then tighten an additional three‑quarters of a turn – never use a wrench to overtighten.
Fill the engine with the correct grade of oil (typically 15W‑40 or 5W‑30 synthetic).
Start the engine and check for leaks.
For severe‑duty applications, replace the filter at every oil change (every 30,000–50,000 km).
Genuine vs. Counterfeit – Protecting Your Engine Investment
Counterfeit oil filters are widespread in Nigeria.
They use low‑quality paper media that tears, inadequate bypass valves that open too early, and weak gaskets that leak.
Symptoms of a counterfeit filter include oil pressure warnings, increased engine noise, and accelerated oil darkening.
Always purchase the 1000-4246-55A filter from authorized Sinotruk distributors.
Genuine parts feature a consistent pleat pattern, robust end caps, and packaging with Sinotruk holograms.
Investing in the authentic filter prevents premature engine wear, turbocharger failure, and costly rebuilds.
Moreover, the genuine 1000-4246-55A comes with a 12‑month manufacturer warranty and technical support.
When combined with other genuine HOWO Parts, you achieve the engine protection that aftermarket filters cannot match.
For fleet owners across West Africa, the slightly higher upfront cost of the 1000-4246-55A pays back many times over in reduced engine repairs, lower oil consumption, and longer engine life.
