2020 Mitsubishi Eclipse Cross oil filter: what it does and when to change it

Yes, the 2020 Mitsubishi Eclipse Cross uses an engine oil filter. This is supported by Mitsubishi’s own technical literature: the Eclipse Cross Owner’s Manual (GK/GL series, 2018–2020) lists “engine oil and filter – replace” in the maintenance schedule, and the Mitsubishi Motors Service Manual for the 4B40 1.5L turbo engine details oil filter removal, installation, and sealing procedures. Major Australian and New Zealand parts catalogues also list a dedicated full‑flow filter for this model. So it’s absolutely a fitted and relevant service item.

On the 2020 Eclipse Cross, the oil filter’s job is to trap fine contaminants—carbon, metal particles, dust—before they circulate through the bearings, camshafts and turbocharger. Clean oil is vital on the 1.5L MIVEC turbo, where tight clearances and turbo speeds demand consistent lubrication. The filter’s bypass valve helps maintain oil flow if the media becomes restricted, but the goal is always to keep the media clean by renewing the filter on time.

For Australia and New Zealand, most schedules call for replacing the oil and filter every 15,000 km or 12 months under normal driving. If the vehicle sees lots of short trips, stop‑start city use, towing, dusty roads, or high heat, treat it as severe service and shorten that to around 7,500–10,000 km or 6 months. Always replace the filter whenever the engine oil is changed—mixing fresh oil with a clogged or old filter defeats the purpose.

When fitting a new filter, check the old gasket isn’t stuck to the housing, lightly oil the new gasket, and spin the filter on by hand until the gasket contacts, then tighten per the filter maker’s turn‑after‑contact instruction (or the torque spec in the service manual). After start‑up, confirm there are no leaks and the oil light goes out promptly.

• Use a quality filter that meets Mitsubishi specifications and the correct oil grade specified for the 4B40 engine.
• If doing lots of short hops, change more often—fuel dilution and moisture can load the filter quickly.
• Watch for signs like noisy starts or an oil warning light, don’t ignore them.
• Dispose of used oil and filters responsibly at a recycling point.

FAQs

What type of oil filter does the 2020 Eclipse Cross use?
It uses a full‑flow spin‑on canister filter mounted on the engine. Reputable filters designed for the 4B40 1.5L turbo engine will specify compatibility with the 2018–2020 Eclipse Cross. Choosing an OE or premium aftermarket filter with the correct bypass and anti‑drainback features is recommended.

How often should the oil filter be changed in Australia or New Zealand?
Under normal conditions, every 15,000 km or 12 months alongside the engine oil. If the vehicle does frequent short trips, towing, dusty work, or heavy stop‑start driving, shorten the interval to around 7,500–10,000 km or 6 months.

Can they extend the interval if running full synthetic oil?
High‑quality synthetic oil helps, but the filter still loads up with contaminants. For engine health—especially protecting the turbo—stick with the time/km schedule. Synthetic oil isn’t a free pass to skip the filter change.
