Oil Maintenance and Service Tips

Regular oil changes are critical for Audi A8 engine longevity and performance. Modern Audi engines use variable oil change intervals, but the standard recommendation is every 10,000 miles or 12 months for vehicles using VW 502 00, 504 00, or 508 00 approved oils. Older D2 and early D3 generation A8 models require more frequent changes at 7,500 miles.

Always use manufacturer-approved oil specifications for your specific engine. Using incorrect oil viscosity or non-approved formulations can lead to reduced fuel economy, increased wear, and potential engine damage. Full synthetic oil is mandatory for all turbocharged engines and strongly recommended for naturally aspirated variants.

Check engine oil level monthly when the engine is cold and the vehicle is on level ground. Oil level should be between the minimum and maximum marks on the dipstick. Replace the oil filter with every oil change using OEM or equivalent quality filters. Torque the drain plug to the specified value using a new aluminum crush washer to prevent leaks.

Severe driving conditions require more frequent oil changes regardless of the oil life monitor reading. High-performance S8 and W12 models benefit from premium synthetic oils like Mobil 1 0W-40 or Castrol Edge 0W-40.

Frequently Asked Questions

What kind of oil does an Audi A8 use?

The Audi A8 requires full synthetic oil meeting specific VW specifications depending on the engine and model year. Modern A8 models (2019+) use VW 508 00 or VW 504 00 approved oils, while older models require VW 502 00 specification. Common viscosity grades include 0W-20, 0W-30, 5W-30, and 5W-40 depending on the specific engine.

How much oil does an Audi A8 take?

Audi A8 oil capacity varies by engine from 6.2 to 11.8 quarts with filter. The 3.0L V6 engines typically require 7-8 quarts, 4.0L V8 engines need 9-10 quarts, and the 6.3L W12 uses 11.8 quarts. Always consult your owner’s manual for the exact capacity for your specific engine.

What is the recommended oil type for an Audi A8?

All Audi A8 models require full synthetic engine oil. Newer models (2019+) need low-viscosity 0W-20 or 0W-30 formulations meeting VW 508 00 or 504 00 specifications. Older models use 5W-30 or 5W-40 synthetic oil meeting VW 502 00 standards. Never use conventional or synthetic blend oil in modern turbocharged engines.

What is the oil change interval for an Audi A8?

The standard oil change interval for most Audi A8 models is every 10,000 miles or 12 months when using VW-approved synthetic oil. Older D2 generation models (1997-2002) require changes every 7,500 miles. Severe driving conditions such as frequent short trips, extreme temperatures, or track use require more frequent intervals of 5,000-7,500 miles.

Can I use 5W-30 instead of 0W-20 in my Audi A8?

Modern Audi A8 models (2019+) are specifically engineered for 0W-20 low-viscosity oil and should not use 5W-30. Using incorrect viscosity can affect fuel economy, emissions, and engine protection. Always follow the viscosity recommendation in your owner’s manual. Older models (2018 and earlier) typically specify 5W-30 or 5W-40 and should not use 0W-20.

What oil filter does the Audi A8 use?

Oil filter part numbers vary by engine and model year. Common OEM filters include 06L115562B for 3.0L TFSI engines, 06E115562A for 4.0L TFSI engines, and 079198405E for 4.2L FSI engines. Equivalent aftermarket filters include Mobil 1 M1-110A, Mann HU 719/7 X, and K&N HP-1017.

Conclusion

The Audi A8 requires specific oil capacities ranging from 6.2 to 11.8 quarts depending on engine size and configuration. Modern models use low-viscosity 0W-20 or 0W-30 full synthetic oil meeting VW 508 00 or 504 00 specifications, while older models require 5W-30 or 5W-40 synthetic oil. Using manufacturer-approved oil with proper viscosity is essential for maintaining engine performance, fuel efficiency, and longevity.

Oil change intervals are typically 10,000 miles or 12 months for modern engines with VW-approved synthetic oil, though severe driving conditions require more frequent service. Always replace the oil filter with each change and torque the drain plug properly with a new crush washer. Following these maintenance guidelines ensures your Audi A8 engine delivers reliable performance and maximum service life.
