Parts for your 2011 Mitsubishi Lancer-Oil pump

2011 Mitsubishi Lancer Oil Pump — what it does and how to look after it

Based on technical references — Mitsubishi Motors Lancer CJ/CF Workshop Manual (Engine: Lubrication), the Mitsubishi ASA electronic parts catalogue, and mainstream repair manuals for 2007–2015 Lancer/Evo — the 2011 Mitsubishi Lancer is absolutely fitted with an oil pump. On 1.8 (4B10), 2.0 (4B11), 2.4 (4B12) and 4B11T turbo engines, it’s a crankshaft-driven gerotor (trochoid) pump integrated into the front cover/balance shaft module. So yes, the oil-pump is relevant and essential on this model.

The oil pump’s job is simple but critical: it pressurises and circulates engine oil to protect bearings, cams and the MIVEC system, and on turbo models it also feeds the turbocharger. Under the bonnet, that steady oil pressure is what keeps the Lancer’s engine quiet, cool and long‑lived. If the pump can’t supply pressure, even briefly, wear accelerates fast — which is why the dash light is treated as a stop‑now warning, not a suggestion.

Good servicing habits are the best protection for the Lancer’s oil-pump. Stick to quality oil and filters that meet the factory spec and change them on time — typically every 10,000–15,000 kilometres or 12 months in Australia and New Zealand, with the shorter interval if the car sees lots of short trips, hot weather, towing or dusty roads. Keeping the oil clean prevents sludge from clogging the pickup strainer and reduces pump wear. During routine services, it’s smart to check for front cover seepage, a weeping front crank seal, and any hint of metallic glitter in the drained oil.

Replacement isn’t a scheduled item
