The 2009 Honda Pilot’s 3.5-liter V6 engine typically requires about 5.5 quarts of engine oil with a new filter; about 5.0 quarts if you do not replace the oil filter.
This article explains the official capacity figures, why there are two numbers, and how to perform a proper oil fill for the 2009 Pilot. It also notes considerations for oil type and checking the level after topping off.
Capacity details and practical notes
Oil capacity can vary slightly depending on whether the oil filter is replaced during the change. The figures below reflect the commonly cited specifications for the 3.5L V6 used in 2009 Pilot models. Always confirm with your owner's manual or a trusted service resource for your specific vehicle variant.
With a new oil filter
Five and a half quarts (5.5 qt) of engine oil are generally recommended when you replace the oil filter during an oil change. This accounts for the oil held in the filter as well as in the engine sump.
Without replacing the oil filter
About five quarts (5.0 qt) of engine oil may be sufficient if the oil filter is not replaced, though this is less common practice for a standard service.
Before performing an oil change, make sure you have the right viscosity for your climate and driving conditions. For many Honda applications, 5W-20 is commonly recommended, but check your manual for your specific region and engine variant.
To ensure accuracy, follow these best practices: always drain completely, replace the oil filter, add oil gradually, and recheck the level with the dipstick after the engine has run and cooled.
In summary, the official capacity for a 2009 Honda Pilot with a 3.5L V6 engine is 5.5 quarts with a new filter and about 5.0 quarts if the filter is not replaced. Always verify with the owner's manual and use the recommended oil type for your conditions.
Summary
The 2009 Honda Pilot takes approximately 5.5 quarts of engine oil when you change the filter, and about 5.0 quarts if you do not replace the filter. Always confirm the exact figure for your specific vehicle variant and use the recommended oil viscosity for your climate. After adding oil, recheck with the dipstick to ensure the level is within the proper range.
