The 2008 Scion tC uses SAE 5W-30 motor oil that meets API SN or ILSAC GF-5 specifications; you can use conventional or full-synthetic oil, with typical change intervals based on driving conditions and oil type. For most drivers, follow the maintenance minder and the owner's manual for exact guidance.
Oil specifications for the 2008 Scion tC
The tC’s 2AZ-FE 2.4-liter engine is designed around modern, energy-conserving oils. The key requirement is a viscosity of 5W-30 and certifications that align with industry standards, which gives you flexibility in choosing brands and blends while ensuring protection and performance.
Recommended oil grade and certifications
Before listing the details, here is a concise guide to the core requirements you should meet when selecting the oil for this engine.
- Viscosity: SAE 5W-30 is standard for the 2AZ-FE engine in the 2008 tC.
- Certification: Oil should meet API SN (or newer) and ILSAC GF-5 standards.
- Oil type: Conventional (mineral) or full-synthetic oil is acceptable, depending on your budget and driving conditions.
Using oil that satisfies these specs helps protect engine components and maintain performance across climate conditions.
Oil capacity and maintenance intervals
Beyond grade and certification, consider the practical maintenance numbers for this model.
- Oil capacity: The engine holds about 4.5 quarts (roughly 4.3 liters) of oil with a full filter change.
- Change interval: With conventional oil, plan for about 5,000 miles (8,000 km) between changes; with synthetic oil, you may extend to roughly 7,500–10,000 miles (12,000–16,000 km) under normal driving, subject to the maintenance minder and driving conditions.
- Oil filter: Replace the oil filter with every oil change to ensure contaminants are removed.
- Other notes: Regularly check the oil level, especially in extreme temperatures or during frequent short trips; follow the maintenance minder for scheduling.
In practice, choose the oil type that matches your driving style and climate, while ensuring it meets the API SN/ILSAC GF-5 standards, and adhere to the maintenance minder for scheduling.
Summary
For a 2008 Toyota Scion tC, use SAE 5W-30 oil that meets API SN or ILSAC GF-5 standards. You may use conventional or full-synthetic oil, with an approximate capacity of 4.5 quarts per change. Follow the vehicle’s maintenance minder to determine oil-change intervals, adjusting for climate and driving conditions.
