2018 Toyota Mark X Oil Filter — What It Does and How To Look After It

Based on Toyota’s GRX130/133 service literature and the Toyota Electronic Parts Catalogue for the GR-series V6 (4GR‑FSE 2.5L and 2GR‑FSE 3.5L), the 2018 Toyota Mark X is factory-fitted with a full‑flow engine oil filter. Genuine Toyota part families listed for this model include 90915‑YZZx (spin‑on assembly) and 04152‑YZZx (cartridge element with housing), depending on engine and production month. Both the Owner’s Manual and Repair Manual specify replacing the oil filter at regular engine oil changes, so the filter is very much relevant and required on the 2018 Mark X.

On this Mark X, the oil filter’s job is straightforward but critical: it traps fine contaminants (metal particles, soot, sludge) so only clean, pressurised oil circulates through the GR V6’s bearings, camshafts and timing components. Keeping that film of clean oil intact helps the engine run quieter, protect against wear, and hold oil pressure on hot days or during quick overtakes.

For day‑to‑day servicing, Toyota schedules typically call for replacing the filter at every oil change. Many owners follow a 10,000 km or 12‑month interval for normal use, and shorten that to 5,000–7,500 km if the car sees lots of short trips, dusty roads, or sustained high‑load driving. Using the correct viscosity (commonly 0W‑20 or 5W‑30 meeting the required API/ILSAC spec) and a quality filter that matches the GR engine’s bypass valve spec keeps things sweet between services.

Signs the Mark X is overdue for an oil and filter service can include oil that’s very dark and gritty on the dipstick, a ticking noise on cold start that lingers, or an oil pressure warning lamp—though that last one means it’s well past time. Whether the engine is fitted with the spin‑on canister or the cartridge element in a reusable housing, the replacement process is simple for a competent tech with the right socket or cup wrench and a new O‑ring where applicable.

Good workshop practice for this model includes:

• Replacing the filter with every oil change and lightly oiling the new gasket/O‑ring.
• Warming the engine before draining, then checking for leaks after refill.
• Resetting the maintenance reminder (if fitted) and recording kilometres and date.
• Disposing of used oil and filters via local recycling rules in Australia and New Zealand.

Sticking to these basics keeps the GR V6 happy, maintains fuel economy, and helps the Mark X rack up high kilometres without drama.

Popular questions about 2018 Toyota Mark X oil filters

What oil filter type fits the 2018 Mark X?

Depending on engine and production month, the 2018 Mark X uses either a spin‑on canister filter or a cartridge element that sits inside a reusable housing. Toyota’s parts catalogue lists compatible genuine families under 90915‑YZZx (spin‑on) and 04152‑YZZx (cartridge). A parts supplier can confirm the exact option from the VIN or engine code (4GR‑FSE or 2GR‑FSE).

How often should the oil filter be changed?

Most owners replace the filter every oil change—typically every 10,000 kilometres or 12 months. If the car does lots of short runs, tows, or drives on dusty roads, shortening the interval to 5,000–7,500 kilometres is a safe bet. Always replace the O‑ring on cartridge housings and check for leaks after start‑up.

Is a genuine Toyota filter necessary, or will a quality aftermarket one do?

A genuine filter is a sure fit and meets Toyota’s bypass valve and filtration specs. A high‑quality aftermarket filter from a reputable brand that matches those specifications is also fine. Avoid no‑name options, correct fit, anti‑drainback performance, and the right bypass pressure are crucial for the GR V6.
