Oil Maintenance and Service Tips

Checking Oil Level

Check engine oil level when the engine is cold and the vehicle is parked on level ground. Wait at least 5 minutes after shutting off the engine for accurate readings. The dipstick should show oil level between the minimum and maximum marks.

Oil Change Intervals

While Audi recommends 10,000-mile oil change intervals, many technicians suggest 5,000 to 6,000-mile intervals for turbocharged and high-performance engines. Severe driving conditions including frequent short trips, extreme temperatures, or towing require more frequent oil changes.

Oil Filter Replacement

Always replace the oil filter during each oil change to ensure proper filtration. Use OEM or quality equivalent filters that meet Audi specifications.

Oil Type Selection

Modern Audi A6 engines require full synthetic oil meeting VW 502.00, 504.00, 508.00, or 509.00 specifications depending on the model year. Using approved oil ensures proper lubrication and maintains warranty coverage.

Oil Drain Plug Torque

Always torque the oil drain plug to 22 lb-ft (30 N·m) to prevent leaks and avoid stripping threads. Replace the drain plug washer or crush washer with each oil change.
