The Scion iA uses 0W-20 synthetic engine oil.
The Scion iA is a Mazda2-based compact sedan that was sold in the United States around the mid-2010s before the Scion brand was retired. Its 1.5-liter SKYACTIV-G engine is designed to run on a 0W-20 synthetic oil for optimal efficiency and protection. Always confirm the exact specification for your specific model year and market in the owner’s manual or with a dealer, as requirements can vary.
Recommended Oil Type
Here are the core specifications you should follow when selecting oil for the Scion iA.
- Viscosity: 0W-20
- Oil type: Full synthetic is preferred; synthetic blend is acceptable if it clearly meets the 0W-20 specification
- Specifications: ILSAC GF-5 (or newer) and API SN (or newer)
- Brand compatibility: Toyota Genuine Oil, Mazda Genuine Oil, or any reputable 0W-20 synthetic that meets GF-5/SN
Using a high-quality 0W-20 synthetic oil and following the manufacturer’s interval helps maintain performance and fuel efficiency for the iA’s engine.
Oil Capacity and Change Interval
Knowing how much oil the engine holds and how often to change it can keep the engine healthy between inspections.
- The 1.5-liter SKYACTIV-G engine typically holds about 3.5–3.7 quarts (roughly 3.3–3.5 liters) of oil with the filter installed.
- Choose 0W-20 synthetic oil; avoid heavier grades unless your manual specifies otherwise.
- Oil-change intervals vary by oil type and driving conditions: commonly around every 5,000 miles (8,000 km) with conventional oil, or about every 7,500–10,000 miles (12,000–16,000 km) with synthetic oil.
- Always replace the oil filter with every oil change and check the level on a level surface after filling the engine.
Notes: Exact capacity and service intervals can vary by model year and market. Always consult the owner’s manual or a certified technician for your exact specification.
Why 0W-20?
0W-20 supports better cold-start lubrication, improves fuel economy, and provides adequate protection for the iA’s engine under typical operating temperatures. This weight has become standard for many modern Mazda/Toyota engines, including the Scion iA’s powertrain.
Summary
In short, the Scion iA takes 0W-20 synthetic oil (GF-5/API SN or newer). The engine holds roughly 3.5–3.7 quarts with a filter, and oil changes are typically advised every 5,000–10,000 miles depending on oil type and driving conditions. Always verify exact specs for your year and market in the owner’s manual or with a dealer.
