Parts for your 2019 Toyota Mark x-Oil filter

2019 Toyota Mark X oil filter — what it does and how to look after it

Toyota’s technical documentation confirms the 2019 Mark X (GRX130, 4GR‑FSE 2.5‑litre and 2GR‑FSE 3.5‑litre V6 engines) is fitted with a serviceable engine oil filter. The Toyota Electronic Parts Catalogue (EPC) lists an “element sub‑assembly, oil filter” for these engines, and Toyota service procedures outline removal and refit of a cartridge‑style filter housed in a reusable cap (commonly serviced with genuine elements such as 04152‑YZZA1 or 04152‑31090, as appropriate to engine and market). The owner’s maintenance schedule also calls for periodic engine oil and filter replacement. So, yes—an oil filter is both relevant and required on the 2019 Mark X.

In this Mark X, the oil filter’s job is simple but critical: trap grit, metal flecks, combustion by‑products and sludge so only clean oil circulates through the V6. Clean oil builds pressure quickly on cold starts, keeps cam phasers and timing chains happy, and protects bearings when the car’s driven hard. Let the filter clog or the O‑ring harden and you risk slow oil pressure build, bypass operation, leaks, or premature engine wear—none of which is a good time under the bonnet.

Servicing is straightforward with the right kit. The GR‑series V6 uses a cartridge element inside a screw‑on housing, a 64 mm, 14‑flute cup tool makes life easier. Always replace the large housing O‑ring and the small drain plug O‑ring supplied with the new element, lightly oil the new seal, and torque the cap and sump plug to factory spec. A quality genuine or OEM‑equivalent element is worth it—they flow properly at cold start and hold contaminants without collapsing.

As a rule of thumb for Australian and New Zealand conditions, plan an engine oil and filter change every 10,000 km or 12 months (whichever comes first), or sooner if the car sees lots of short trips, dusty roads, or enthusiastic weekend drives. Between services, keep an eye out for:

• Weeping around the filter housing cap (aged O‑ring)
• Oil pressure warning lights or rattly cold starts
• Very dark, gritty oil on the dipstick soon after a change

Stick to the servicing rhythm and the Mark X’s smooth V6 will stay silky, efficient, and ready to tour.

Popular questions about 2019 Toyota Mark X oil filters

Which oil filter type does the 2019 Mark X use?
The 2019 Mark X uses a cartridge‑style oil filter element that fits into a reusable housing on the engine. Genuine Toyota elements (for example, 04152‑YZZA1 or 04152‑31090, depending on engine variant) are commonly specified for the 4GR‑FSE and 2GR‑FSE V6s.

How often should the oil filter be changed?
In local AU/NZ conditions, changing the oil and filter every 10,000 km or 12 months keeps the GR‑series V6 in top nick. If the vehicle does mostly short trips, towing, or dusty driving, consider shorter intervals.

Can a clogged filter damage the engine?
Yes. A severely restricted filter can trigger the bypass, letting unfiltered oil circulate, and may delay oil pressure on start‑up. Over time that can accelerate wear on camshafts, chains, and bearings. Regular, quality filter changes prevent this.
