2016 Mitsubishi ASX Oil Pump — What It Does and When to Service It

Yes, the 2016 Mitsubishi ASX absolutely uses an engine oil pump. Mitsubishi Motors’ workshop literature for the GA/CF-series ASX (sold as ASX/Outlander Sport/RVR) details a crankshaft-driven trochoid/gear-type oil pump set into the front cover on the 4B11/4B12 petrol engines, with a gear/chain-driven pump on the 4N1-series diesels. The factory service manual’s Engine Lubrication section outlines pump operation, pressure checks and relief valve function, and the OEM parts catalog lists the oil pump assembly, pickup and related seals for these engines. So the oil pump is not only relevant—it’s essential hardware on every 2016 ASX.

The oil pump’s whole job is to push the right amount of oil, at the right pressure, through the engine. It feeds crank and rod bearings, cam journals and timing components, and it supports systems that rely on stable oil pressure, like MIVEC variable valve timing on petrol models. Without a healthy pump and clean oil, wear ramps up fast—especially in Aussie and Kiwi conditions with heat, towing, short trips or dusty roads.

There isn’t a scheduled replacement interval for the pump itself. Instead, good servicing keeps it happy: use the correct grade and spec oil for your climate, replace the oil and filter on time, and fix any leaks quickly so the pickup doesn’t suck air. If the oil pressure warning lamp flickers, if there’s persistent top-end ticking or bottom-end rumble, or if diagnostics log oil-pressure-related faults, it’s time for proper checks with a mechanical gauge and a look at the pickup, relief valve and clearances.

When replacement is needed, it’s a front-cover and sump-off job on these engines. Best practice is to:

• Inspect and clean or replace the pickup screen and O-ring.
• Check the pressure relief valve for sticking or scoring.
• Prime the new pump with clean oil before refitting.
• Use quality seals and gaskets, and consider a new front crank seal.
• Verify oil pressure hot at idle and at revs after reassembly.

Plenty of “oil pump scares” turn out to be tired oil, a clogged pickup, a failing pressure sensor, or bearing wear lowering pressure. A technician who knows the ASX layout and follows the Mitsubishi service steps will sort the cause quickly and help the engine rack up more kilometres without drama.

Popular questions about 2016 Mitsubishi ASX oil pumps

Does a 2016 ASX actually have an oil pump, and where is it?

Yes. Factory service manuals for the GA/CF-series confirm an engine-driven trochoid/gear-type oil pump. On petrol models it’s integrated into the front cover and driven by the crankshaft, on diesels, it’s gear/chain-driven. Access typically involves removing the front cover and sump.

When should the oil pump be replaced on a 2016 ASX?

It’s not a routine replacement item. Consider replacement only if verified low oil pressure, internal pump wear or a sticking relief valve is found, or during a major rebuild. Always rule out thin/old oil, a clogged pickup, sensor faults or bearing wear first.

How can owners prolong oil pump and lubrication system life?

Stick to the correct oil grade and change intervals, use quality filters, and keep an eye out for leaks. For vehicles that tow, idle a lot, or see dusty conditions, shorten oil change intervals. Periodic inspections of the sump area and addressing warning-light flickers early go a long way.
