Approximately 4.7 quarts (about 4.4–4.5 liters) of oil are needed when changing the oil with the filter installed; about 4.0 quarts (roughly 3.8–4.0 liters) if you’re replacing the oil but not the filter. This figure comes from the official capacity for the 2AZ-FE 2.4L engine used in the 2010 tC.
The 2010 Scion tC uses the 2AZ-FE 2.4-liter engine. Getting the oil quantity right is essential for engine lubrication and longevity. This article outlines the official capacity figures and practical guidance for checking and maintaining the correct oil level.
Oil capacity and measurement
The following figures reflect standard capacity for the 2.4L engine in the 2010 tC when performing an oil change.
- Oil capacity with filter: 4.7 quarts (approximately 4.4–4.5 liters)
- Oil capacity without filter: 4.0 quarts (approximately 3.8–4.0 liters)
When performing an oil change, start by adding oil a little at a time and use the dipstick to verify the level as you approach the full mark. If you’re unsure, it’s safer to err on the side of a slightly underfilled engine and top up gradually after rechecking the dipstick.
Oil type and maintenance guidelines
Choosing the right viscosity and following the recommended maintenance schedule helps protect the engine and optimize performance in a range of climates.
- Viscosity: 5W-20 is the most commonly recommended grade for the 2AZ-FE in this era; 5W-30 may be acceptable in warmer climates or per the owner’s manual. Verify the exact specification on the oil filler cap and in the manual.
- Oil type: Full synthetic oil is highly recommended for best protection; conventional or semi-synthetic oils can be used if synthetic is unavailable, but consult your manual for any climate-specific notes.
- Change interval: Follow the factory schedule, typically around 5,000 miles (8,000 km) for conventional oil and up to about 7,500 miles (12,000 km) or more for synthetic oil, with more frequent changes under severe driving conditions. Always refer to the owner’s manual for the precise interval.
Bottom line: confirm the exact capacity and viscosity for your vehicle in the owner's manual or by contacting a Toyota service center, and use the dipstick to ensure the level stays within the stamped marks after each change.
Summary
For the 2010 Scion tC 2.4L, the official oil capacity is about 4.7 quarts with the filter and about 4.0 quarts without. Use a compatible oil (commonly 5W-20) and follow the manufacturer’s change interval, adjusting for climate and driving conditions. Always verify with the owner’s manual and check the dipstick to keep the oil level within the recommended range.
For specific maintenance guidance, consult the 2010 Scion tC owner’s manual or a Toyota service professional to ensure you’re following the latest recommendations.
