2022 Subaru Impreza Oil Cap

Yes, the 2022 Subaru Impreza is fitted with an engine oil filler cap. Technical references including the 2022 Subaru Impreza Owner’s Manual (engine compartment overview), Subaru service information for the FB20 2.0‑litre boxer engine (lubrication section), and genuine Subaru parts catalogues all list and illustrate the engine oil filler cap and its sealing gasket as standard equipment. So the oil-cap is relevant, used, and essential on this model.

The oil cap’s job is simple but critical. It seals the filler neck to keep oil in, dirt and moisture out, and to maintain correct crankcase ventilation behaviour. On most Aussie and NZ‑spec 2022 Imprezas it also doubles as a handy reminder of the correct oil grade, typically showing 0W‑20. Under the bonnet, the cap sits right on top of the engine—easy to spot and easy to remove when topping up.

Because the cap lives in a hot, busy engine bay, its O‑ring or gasket can harden over time, the threads can pick up grit, and the cap itself can become brittle. As part of routine servicing, it’s smart to give it a once‑over. Wipe away grime, make sure it threads on smoothly, and nip it up hand‑tight until it seats—no need to reef on it. If the O‑ring looks flattened or cracked, replace it. A quality genuine or OE‑equivalent cap with the correct seal is the go.

• Replace the oil cap if it’s cracked, warped, or won’t tighten securely
• Renew the seal/O‑ring if it’s perished, swollen, or weeping oil
• Watch for oil mist under the bonnet, a whiff of hot oil, or a cap that loosens—these point to a dodgy cap

Driving without a cap, or with a damaged one, can spray oil around the engine bay, invite dust into the engine, and upset crankcase ventilation—sometimes even triggering a warning light or rough running. If the cap goes missing, avoid driving far
