For the 2008 Chevrolet Avalanche with the 5.3 L V8 engine, the oil capacity is 6 quarts with a filter. To optimize performance, it is recommended to use 5W-30 Synthetic oil, with a torque of 18 ft/lbs for the drain plug. Synthetic oil is artificially made with chemical compounds and contains fewer impurities compared to conventional oil. Regular oil changes are crucial for maintaining a clean and efficient engine. It is advised to change the oil and filter every 10,000 miles or 12 months, whichever comes first. The approximate cost for an oil change ranges from $30 to $40 for labor and additional parts.
You'll need 6.0 quarts of oil when changing the filter. If you're not changing the filter, use 5 quarts and then add more as needed after a 15-minute drive.
The 2008 Chevy Avalanche, equipped with a 5.3L engine, requires 6 quarts of oil for optimal performance.
