Best Engine Oil for Mazda CX-3 2.0 SKYACTIV-G (121 HP)
The Mazda CX-3 is a compact crossover that competes with the Renault Captur and Peugeot 2008. Its PE-VPS SKYACTIV-G engine is a 1,998cc naturally aspirated four-cylinder producing 121 HP — the same engine family found in the CX-5 and Mazda 3. Like the smaller P5-VPS in the Mazda 2, the PE-VPS achieves efficiency through a high 13:1 compression ratio and direct injection rather than turbocharging. The CX-3 requires 0W-20 viscosity — thinner than the Mazda 2’s 5W-30 — reflecting Mazda’s push for fuel economy in the highly competitive small SUV segment.
Quick Answer: Recommended Oil
For Mazda CX-3 2.0 SKYACTIV-G (121 HP):
- Recommended viscosity: SAE 0W-20
- Oil capacity: 4.2 litres with filter (3.9 L without)
- Required norm: ACEA A5/B5
SKYACTIV-G 2.0: Direct Injection at 13:1
The PE-VPS is a 1,998cc inline four-cylinder with an aluminium block, timing chain, and direct fuel injection operating at up to 200 bar. Unlike the smaller Mazda 2’s port injection, the CX-3 uses direct injection for improved efficiency under load. This means carbon buildup on the intake valves is a long-term concern — expect symptoms between 60,000-100,000 miles. Walnut blasting is the accepted remedy.
Naturally aspirated advantage: No turbocharger means no turbo-related failure modes, no turbo coking, and no oil coking in turbo bearing housings. The PE-VPS is mechanically simpler than turbocharged competitors like the VW 1.0 TSI or Peugeot 1.2 PureTech. Reliability is excellent.
0W-20 viscosity is Mazda’s fuel economy requirement. The engine’s bearing clearances are designed for this thin viscosity. Do not substitute 5W-30 unless 0W-20 is completely unavailable.

Conclusion
The Mazda CX-3 2.0 SKYACTIV-G requires ACEA A5/B5 oil in SAE 0W-20, with 4.2 litres capacity. Naturally aspirated high-compression with direct injection — simpler and more reliable than turbocharged competitors, with carbon buildup as the only long-term maintenance concern.
