The standard specification for the 2008 Scion xD is 5W-20 engine oil that meets API SN and ILSAC GF-5. A full synthetic oil is preferred for longevity and protection, while a high-quality synthetic blend is acceptable if necessary. In very cold climates, some markets may specify 0W-20; always verify the exact requirement on the oil cap or in the owner's manual.
Recommended oil type and viscosity
For the 2008 Scion xD, the typical recommendation is 5W-20 engine oil that meets API SN and ILSAC GF-5. The preferred option is a full synthetic; a synthetic blend is acceptable if necessary. In extremely cold climates, 0W-20 may be permitted if your manual specifies it; always confirm with the owner's manual or the oil cap on the engine.
Choose from these approved options:
- 5W-20 full synthetic motor oil (API SN/ILSAC GF-5 or newer) – recommended for best protection and fuel efficiency.
- 5W-20 synthetic blend – acceptable if full synthetic is unavailable.
- 0W-20 full synthetic – only if the owner's manual explicitly allows it for your climate.
Conclusion: The most common and recommended choice is 5W-20 full synthetic that meets API SN and ILSAC GF-5. Use 0W-20 only if the manual explicitly allows it; otherwise, stick with 5W-20.
Specifications and practical notes
Engine oils for this model should carry API SN or newer and ILSAC GF-5 or newer specifications. Avoid oils that don’t meet these specs or that carry non-approved performance ratings. Using an approved viscosity and specification helps maintain fuel economy, emissions compliance, and engine protection over the vehicle’s life.
How to verify the correct oil on your engine
Check the oil filler cap and the owner's manual for the exact viscosity recommended for your climate. Look for markings such as 5W-20 and confirm that the oil meets API SN and ILSAC GF-5. When in doubt, ask a Toyota dealer or a trusted mechanic to confirm the specification for your vehicle’s year and region.
Maintenance considerations and intervals
Oil change intervals vary by oil type and driving conditions. With synthetic oil, many owners extend intervals beyond conventional limits, often up to about 7,500 miles under normal conditions, while conventional oil is commonly changed around 3,000–5,000 miles. Always follow the schedule in the owner’s manual and adjust for aggressive driving, high temperatures, or frequent short trips.
Summary
The 2008 Scion xD uses 5W-20 engine oil, preferably a full synthetic that meets API SN and ILSAC GF-5. In very cold climates, 0W-20 may be permitted if specified by the manual, but if in doubt, stick with 5W-20. Always verify the exact requirements on the oil cap or in the owner’s manual and follow the manufacturer’s recommended maintenance intervals to keep the engine performing optimally.
