2010 Nissan Dualis sump plug washers
Yes, the 2010 Nissan Dualis (J10, known elsewhere as Qashqai) uses a sump plug washer. Nissan’s factory service information for the J10 platform specifies refitting the drain plug with a new gasket/washer at each oil change, and dealer parts catalogues list an oil drain plug gasket for this model. In plain terms: it’s a small, soft “crush” washer that seals the sump plug so engine oil doesn’t seep past the threads.
On the Dualis, the sump plug washer is typically a 14 mm crush type in aluminium or copper. When the plug is tightened to the factory torque, the washer deforms slightly to match the mating surfaces, creating a reliable seal. Because it’s designed to deform once, reusing it can lead to weeping, drips on the driveway, or the plug needing over-tightening—none of which is ideal for the alloy sump or the threads.
As part of regular servicing, replacing the sump plug washer whenever the engine oil is changed is the easy, low-cost move that prevents leaks and saves headaches. A genuine Nissan washer or a quality aftermarket equivalent does the job nicely. If it’s ever been reused in a pinch, keep an eye out for a light oil mist around the plug after a few heat cycles—if there’s any sign of dampness, swap it straight away.
Good practice on a 2010 Dualis includes:
- Always fit a new crush washer whenever the sump plug is removed.
- Clean the plug and the sump’s sealing face, no sealant is required or recommended.
- Tighten the plug to the factory spec in the service manual—snug, not gorilla tight.
- Confirm the washer’s size and material against the vehicle’s build/vin if in doubt.
- After the first short drive, check underneath for any fresh oil around the plug.
Technical references: Nissan J10 Qashqai/Dualis Factory Service Manual (Engine Mechanical – Lubrication System) notes to “install drain plug with new gasket,” and Nissan parts catalogues for the J10 list an oil drain plug gasket (crush washer) for MR20DE petrol and applicable diesel variants. That’s why every proper Dualis service includes a fresh washer—cheap insurance for a tight, leak-free seal.
Popular questions
Does a 2010 Nissan Dualis actually need a sump plug washer?
Yes. The J10 Dualis uses a crush-type washer on the sump plug. Nissan’s service documentation specifies fitting a new washer whenever the plug is refitted, which is why most service kits and dealers include one with an oil change.
How often should the Dualis sump plug washer be replaced?
Every time the sump plug comes out—typically at each oil change. It’s a single-use crush washer, reusing it risks small leaks or the need to overtighten the plug, which can damage threads over time.
What size or type washer fits the 2010 Dualis?
It commonly takes a 14 mm crush washer in aluminium or copper. Because markets and engines can vary, it’s smart to match by VIN or take the old washer to compare thickness and inner diameter before purchase.
