2024 Mitsubishi ASX Oil Pump — What It Does and How to Look After It

Based on technical documentation for the engines fitted to the 2024 Mitsubishi ASX, an engine oil pump is absolutely used and relevant on this model. For Australia and New Zealand, the ASX typically runs the 2.0-litre MIVEC petrol (4B11), which features a crankshaft-driven trochoid oil pump housed in the front cover (Mitsubishi 4B1 Engine Service Manual, Lubrication System). European-spec 2024 ASX models, which are based on Renault’s Captur platform, use Renault petrol and hybrid powertrains (e.g., HR10/HR13 and 1.6 hybrid) that also employ a crank-driven oil pump, often variable-displacement (Renault H5Ht/HR13 Technical Guide, Lubrication). The 2024 ASX Owner’s Manual outlines oil and filter servicing, the oil pump itself is not listed as a routine service item.

The oil pump’s job is simple but critical: it pushes pressurised oil through the engine to protect bearings, camshafts, timing components, and (on turbo variants) the turbocharger. It keeps oil flowing on cold starts, helps stabilise oil pressure as revs change, and ensures variable valve timing hardware gets the supply it needs. Without a healthy pump, metal-to-metal contact, heat build-up, and rapid wear become real risks.

For everyday servicing, the oil pump doesn’t need scheduled replacement. What it does need is clean, correctly specified oil and a quality filter at the recommended intervals. Owners should follow the handbook schedule (commonly around every 12 months or 15,000 kilometres, usage dependent) and use the manufacturer-specified oil grade. Many 2024 ASX variants call for modern low-viscosity oils (e.g., 0W-20 or 5W-30) meeting API SP/ILSAC GF-6, Renault-based engines may specify an RN-rated oil as listed in the handbook. Keeping the oil level correct and avoiding extended drain intervals goes a long way to preserving pump life.

Replacement is generally only considered when symptoms point to a lubrication issue or during engine overhaul. The 4B11’s pump is integrated with the front case and driven by the crankshaft, Renault-based units may be variable-displacement and chain-driven. Either way, it’s a workshop job requiring front cover access, timing components removal, sealing work, and precise reassembly. Always prime the new pump with clean oil, renew the pickup O-ring, clean the strainer, and verify oil pressure with a mechanical gauge on first start.

• Signs an oil pump may need attention:
  • Oil-pressure warning lamp, low-pressure fault codes, or lifter/timing chain rattle at idle
  • Turbo whine or smoke on TCe variants, especially after oil starvation
  • Metallic debris in the sump or filter, repeated oil contamination
  • History of bearing damage or sludge — replace the pump during rebuilds

Popular questions

Does the 2024 Mitsubishi ASX have an oil pump?
Yes. Both the AU/NZ 2.0-litre MIVEC (4B11) and the Renault-based engines used in some markets run a crank-driven oil pump, with some Renault units being variable-displacement. This is confirmed in the respective workshop manuals and lubrication system diagrams. The Owner’s Manual covers oil and filter servicing, the pump itself is not a periodic service item.

When should the oil pump be replaced?
There’s no scheduled replacement. Consider it if there’s persistent low oil pressure, noisy valve-train or timing chain on hot idle, bearing damage, metal in the oil, or after a lubrication-related engine failure. It’s typically replaced during major engine work, and always after severe oil starvation events.

What oil should be used to keep the pump healthy?
Use the oil grade and specification in the handbook. Many 2024 ASX petrol variants specify 0W-20 or 5W-30 meeting API SP/ILSAC GF-6, Renault-based engines may call for an RN-rated oil. Service intervals are commonly around 12 months/15,000 kilometres in AU/NZ conditions, but follow the maintenance schedule that applies to your exact engine and usage.
