2018 Suzuki Splash Oil Filter — What it does and how to look after it

Yes, the 2018 Suzuki Splash uses an engine oil filter. Technical sources confirming this include the Suzuki Global Service Manual for the K10B/K12B petrol engines (the Splash’s common powerplants), which specify a full‑flow spin‑on oil filter, and the Suzuki Electronic Parts Catalogue (EPC) for the Splash (PA), which lists genuine oil filter part numbers applicable to these engines. Typical genuine references include 16510‑81403 (often superseded to 16510‑81420) or market‑equivalent listings. These sources make it clear an oil filter is fitted and required for regular servicing.

On a 2018 Suzuki Splash, the oil filter’s job is to trap the fine metal particles, combustion by‑products, and general grime that end up in the engine oil as the car clocks up the kays. Keeping that muck out of the oil galleries protects bearings, camshafts and the variable valve timing hardware, helping the little Suzuki run smoother for longer and use less fuel.

As part of routine servicing, it’s best practice to replace the oil filter at every engine oil change. For most Aussie and Kiwi drivers, that’s typically every 10,000–15,000 km or 12 months, whichever comes first. If the Splash spends its life in short trips, hot summers, dusty roads, or lots of stop‑start traffic, shorten the interval to the earlier side. Fresh oil plus a new filter is cheap insurance against premature wear.

When replacing the filter:

• Choose a quality filter that matches the K10B/K12B specs (genuine Suzuki or a reputable aftermarket cross‑reference).
• Warm the engine briefly so the oil flows out cleanly, then drain the oil before removing the old filter.
• Wipe the filter seat, lightly oil the new filter’s rubber gasket, and spin it on by hand until the gasket contacts, then tighten as directed on the filter (usually about three‑quarters of a turn). No need to overdo it with a wrench.
• Refill with the correct grade and quantity of oil, start the engine, check for leaks, then recheck the level after a few minutes.

A blocked or tired filter can leave the engine relying on a bypass, circulating unfiltered oil. That means extra wear, noisy starts, and potentially higher oil consumption. Keeping the oil and filter on schedule helps the Splash feel perky, keeps emissions gear happier, and maintains warranty or insurer goodwill on service history.

Popular questions

How often should the oil filter be changed on a 2018 Suzuki Splash?
Most owners will be well covered changing the oil filter every 10,000–15,000 km or 12 months with the engine oil. If the car does lots of short trips or coping with dusty or hot conditions, stick to the shorter end of that range.

Which oil filter fits the 2018 Suzuki Splash?
For K10B/K12B engines, genuine Suzuki filters commonly reference 16510‑81403 (often superseded to 16510‑81420). Quality aftermarket equivalents matched to those numbers are fine. Always cross‑check by VIN or engine code before buying.

Can a home mechanic change the Splash’s oil filter?
Yes, if comfortable with basic spanner work. The job is straightforward with the right tools, a drain pan, and the correct oil. Take care with hot oil, use proper jacking support if needed, and dispose of used oil and the filter at a recycling point.
