Under normal highway conditions, change oil every 30,000 km (or 12 months) using Weichai-approved 15W‑40 grade. For severe duty (dusty, high load, stop-go), shorten to 20,000 km. Always replace the genuine filter simultaneously to maintain B10 life of 1.2 million km.
Yes, WP12 engines are compatible with B20 (20% bio-diesel blend) without any modification. For higher blends like B100, we recommend consulting Weichai’s technical team for fuel system upgrades. All WP12 common‑rail systems use corrosion‑resistant materials for renewable diesel.
Absolutely. All genuine Weichai remanufactured WP12 engines and components come with a 12‑month or 100,000 km warranty (whichever comes first). The warranty covers defects in materials and workmanship, and is honored across our authorized service network globally.
WP12 engines are factory standard for Sinotruk HOWO (T7H series), Shacman X3000, Foton Auman EST, Dongfeng KL, and many regional brands. They are also popular as replacement engines for Volvo, MAN, and Mercedes chassis due to similar mounting points.
The WP12 engine is tested to start reliably at -35°C with standard cold‑start kit (grid heater and high‑cranking battery). For -40°C environments, optional ether injection and block heater are available. Many Russian and Canadian fleets operate WP12 without issues during harsh winters.
WP12 is offered in Euro V (current main market), Euro VI (select markets), and China VI. Retrofit kits for upgrading from Euro III to Euro V are also available. All versions use selective catalytic reduction (SCR) and exhaust gas recirculation (EGR) for compliance.
