2018 Volvo XC60 oil cap — purpose, care, and quick replacement tips

Yes, the 2018 Volvo XC60 uses an engine oil filler cap. This is confirmed by Volvo’s 2018 XC60 Owner’s Manual, which labels the oil filler under the bonnet in the engine-compartment overview, and by Volvo VIDA (service information) procedures that reference removing/refitting the cap during oil changes. Genuine Volvo parts catalogues for SPA-platform engines (Drive‑E petrol and diesel, including T5, T6, D4/D5 and T8) also list a dedicated oil filler cap with an integral seal.

The oil cap’s job is simple but critical. It seals the top of the engine where oil is added, keeping dust and moisture out while helping the crankcase ventilation system maintain the right pressure. A sound cap prevents oil mist from weeping onto the cam cover and stops that hot-oil whiff that can creep into the cabin. Many caps are marked with the oil-can symbol and sometimes viscosity guidance
