The oil specification for a Scion tC depends on its model year. Older tCs typically call for 5W-30 engine oil, while later models generally require 0W-20 full synthetic. Always verify with your owner's manual or the oil filler cap on your engine.
To determine the exact requirement for your car, check the manual, the oil cap, or ask a Toyota dealer. The following breakdown covers the main generations and their typical oil specifications to help you identify the correct oil for your Scion tC.
Generations and oil specifications
First generation (2004–2010)
Overview: The first-generation Scion tC uses the 2AZ-FE 2.4L engine. Oil requirements for this engine are generally in the 5W-30 range, with a preference for synthetic or synthetic-blend oils.
Oil recommendations for the first generation include:
- Oil type: SAE 5W-30, synthetic or synthetic-blend
- Oil specification: API SM (or newer) or equivalent
- Oil capacity: approximately 4.4–4.8 quarts (with filter), depending on year and model
- Change interval guidance: typically about every 5,000–7,500 miles (8,000–12,000 km) when using synthetic oil; more frequent intervals apply if using conventional oil
Conclusion: For the first-generation tC, 5W-30 synthetic or synthetic-blend oil is the common recommendation, but always confirm for your exact year and climate.
Second generation (2011–2016)
Overview: The second-generation Scion tC moved to a 2.5L engine (2AR-FE) with different oil expectations. In most markets, 0W-20 full synthetic is the preferred viscosity for fuel efficiency and protection.
Oil recommendations for the second generation include:
- Oil type: SAE 0W-20, full synthetic
- Oil specification: API SN (or newer), ILSAC GF-5 (and newer standards as applicable)
- Oil capacity: about 4.5–4.7 quarts (with filter)
- Change interval guidance: typically about every 5,000–7,500 miles (8,000–12,000 km) with synthetic oil; follow the manual for severe driving conditions
Conclusion: For the later Scion tC models, 0W-20 full synthetic is the typical recommendation, but always verify for your exact year and local climate.
Summary
The Scion tC’s oil requirements vary by model year. Early tCs (2004–2010) generally call for 5W-30, while later models (2011–2016) typically use 0W-20 full synthetic. Always confirm the exact specification by checking your owner's manual or the oil filler cap, and follow the advised oil capacity and change intervals to maintain engine health.
What type of oil does my 2007 Scion tC take?
Oil Grade: API*
| Viscosity: | 0W-20, 5W-20 (All TEMPS) |
|---|---|
| Capacity: | 4 quarts (with filter). After refill check oil level. |
| Torque: | 30 ft/lbs (Oil Drain Plug) |
What is the bad year for the Scion tC?
Avoid: 2007 Scion tC
According to CarComplaints, the 2007 tC is the worst model year of this vehicle, with 194 complaints and two recalls. The most significant problems reported include excessive oil consumption, power window failure, and rough shifting.
Can I run 5W-30 instead of 0W-20?
Modern engines designed for 0W-20 oil require specific viscosity for optimal performance, and using thicker 5W-30 oil may compromise efficiency while potentially voiding manufacturer warranties.
Does it matter if I use 5W-30 or 5W-40?
The key difference between 5W30 and 5W40 engine oils is their high-temperature viscosity. 5W30 is thinner at operating temperature, offering better fuel efficiency, while 5W40 is thicker, providing enhanced engine protection under high loads, long-distance driving, or hot climates.
