Parts for your 2023 Mitsubishi Eclipse cross-Oil pump

2023 Mitsubishi Eclipse Cross oil pump — purpose, fitment and service tips

Yes, the 2023 Mitsubishi Eclipse Cross is fitted with an engine oil pump. Mitsubishi Motors workshop literature for the Eclipse Cross (engine lubrication section for the 1.5L turbo petrol 4B40 and the 2.4L Atkinson-cycle petrol used in the PHEV) describes a crankshaft-driven oil pump within the front cover, and the Mitsubishi ASA electronic parts catalogue lists an “oil pump assembly” for these engines. Those technical sources confirm the oil pump is a standard component of the 2023 model’s powertrains.

What does it do? The oil pump is the heart of the lubrication system, pressurising and circulating engine oil through galleries to bearings, camshafts, VVT mechanisms and the turbocharger (on the 1.5T). Under the bonnet, it keeps friction down, carries heat away, and helps the engine live a long, hassle-free life.

• Builds and regulates oil pressure for bearings and cam lobes
• Feeds the turbocharger’s bearing (1.5T) and supports variable valve timing
• Moves oil through the filter and cooler paths for cleaner, cooler lubrication

It’s not a consumable, so there’s no routine replacement interval. Longevity comes from clean oil and the correct grade. Following the logbook service schedule (typically every 15,000 kilometres or 12 months in Australia and New Zealand, conditions depending) and using the specified viscosity—often 0W-20 for these engines, or an approved alternate such as 5W-30 where climate or usage warrants—will keep the pump happy. A quality filter with the correct bypass specification matters just as much.

• Watch for symptoms: low oil pressure warning, rattly cold starts, turbo whine, metallic glitter in drained oil, or fault codes related to oil pressure/VVT.
• Good service checks: inspect for leaks, verify pressure with a mechanical gauge if concerns arise, and ensure the pick-up screen isn’t restricted.

If replacement is needed (after contamination, wear, or verified low pressure), it’s a front-of-engine job: removing the sump and front cover, renewing the pump, pick-up O-ring, seals and sealant, and priming the pump with clean oil. Fresh oil and filter are mandatory, and the strainer should be cleaned or replaced. Correct torque and sealing procedures from the workshop manual are essential.

For Eclipse Cross PHEV owners, the internal combustion engine still relies on its oil pump. Even with plenty of electric driving, every ICE start needs prompt oil pressure, so regular engine oil services remain crucial.

• Use the handbook-approved oil grade and capacity in litres
• Stick to time/kilometre intervals, especially if doing short trips
• Choose genuine or premium filters to protect pressure stability

Popular questions

Does the 2023 Eclipse Cross definitely have an oil pump?
Yes. Both the 1.5L turbo petrol and the 2.4L petrol in the PHEV use a crankshaft-driven oil pump as detailed in Mitsubishi’s engine lubrication section of the workshop manual, and it’s listed as an assembly in the official parts catalogue. It’s a core, always-on component of the engine.

When should the oil pump be replaced on a 2023 Eclipse Cross?
There’s no scheduled replacement. It’s replaced only when diagnostics show low oil pressure, internal wear, damage from debris, or after a major engine rebuild. Proper oil and filter changes at the recommended intervals are the best prevention.

What oil should be used to protect the pump and engine?
Use the viscosity and specification shown in the owner’s handbook—commonly 0W-20 for these engines, with approved alternatives like 5W-30 depending on climate and usage. In Australia and New Zealand, servicing every 15,000 km or 12 months (or as specified) with a quality filter helps maintain stable oil pressure and pump health.
