2020 Suzuki Splash Oil Cap — What it does and how to look after it

Referencing Suzuki’s own technical material, the 2020-registered Suzuki Splash does use an oil cap. The Suzuki Splash Owner’s Manual shows the “Engine oil filler cap” in the engine-bay layout, and the Suzuki Electronic Parts Catalogue (for Splash/Ritz with K10B/K12B engines) lists an oil filler cap mounted to the rocker/cam cover. That makes the oil cap a relevant, fitted component on any 2020 Splash still on the road.

The oil cap on a 2020 Suzuki Splash is a small bit of plastic and rubber doing a big job. It seals the oil filler neck on the cam cover, keeping the engine oil clean and inside the engine while also preventing dust and moisture from getting in. When it’s removed, it’s the entry point for fresh oil during a service, when it’s installed, it’s a pressure-resisting lid that stops oil mist from escaping. Because the Splash’s K‑series petrol engines rely on clean, well-contained oil for lubrication and cooling, a healthy cap and O‑ring are a must.

As part of routine servicing, it’s smart to give the cap a once‑over. Wipe off any grime, check the O‑ring for flattening, nicks or hardening, and make sure the cap twists on smoothly and seats positively. A light smear of fresh engine oil on the O‑ring helps it seal and prolongs its life. Hand‑tight is the go—snug it down until it stops, there’s no need to overdo it. If the cap is cracked, the tabs are worn, or the O‑ring is perished, replace it straight away with a quality OEM‑equivalent that matches the Splash’s engine.

• Look for oil mist around the filler neck or under the bonnet—often a hint the cap isn’t sealing.
• Watch for a whiff of burnt oil after drives—another clue to cap or O‑ring issues.
• Inspect the cap at every oil change, replace the O‑ring when it’s brittle or flattened.
• Never drive without a cap—oil can spurt out, contaminate the bay, and let grit into the engine.

If the cap’s gone missing, don’t run the car. An open filler invites dust and moisture that can accelerate engine wear. A new cap is inexpensive, protects the engine, and helps maintain correct crankcase ventilation behaviour. For the 2020 Suzuki Splash, keeping the oil cap clean, correctly seated, and leak‑free is an easy, high‑value win at each service.

FAQs

Where is the oil cap on a 2020 Suzuki Splash?
The oil cap sits on top of the engine’s cam/rocker cover under the bonnet, usually marked with an oil can symbol. On K‑series Splash engines it’s a twist‑to‑lock design that removes by turning anticlockwise and reinstalls with a firm hand‑tight turn clockwise.

Because engine bay layouts can vary slightly by market and engine variant (K10B vs K12B), the exact left/right position on the cover may differ, but it’s always on the top of the engine and easy to spot.

How often should the Splash’s oil cap or O‑ring be replaced?
There’s no fixed kilometre interval for the cap itself—inspect it at every service. Replace the O‑ring as soon as it shows flattening, cracks, or hardening, or if you notice oil mist near the filler neck. Many owners find an O‑ring refresh every few years keeps things tidy and leak‑free.

Can a loose or missing oil cap cause issues?
Yes. A loose cap can allow oil vapour and droplets to escape, leading to mess under the bonnet and a whiff of oil. A missing cap risks rapid oil loss and contamination from dust and moisture—don’t drive the car until a proper cap is fitted.
