The 2019 Ridgeline's 3.5-liter V6 engine uses about 5.0 quarts of engine oil when performing an oil change with a new filter.
The Ridgeline shares its V6 with other Honda models, and the official specification calls for a full-synthetic or synthetic-blend oil change using the filter. The typical quantity is 5.0 quarts (approximately 4.7 liters) for a standard drain-and-fill, though you should always verify the exact amount for your VIN and local conditions in the owner's manual. The recommended oil viscosity for most climates is 0W-20 synthetic, with 5W-20 listed as an alternative in some regions; always confirm the current specification for your vehicle.
Oil capacity and related specifications
The following information helps plan an oil change for the Ridgeline's 3.5L V6. The list summarizes the key numbers and guidance you should know before topping up or changing oil.
- Oil capacity with filter: 5.0 quarts (4.7 liters).
- Recommended oil type and viscosity: 0W-20 synthetic is standard for most environments; 5W-20 may be acceptable in some locales—verify in the owner's manual or with a Honda dealer.
- Oil change interval (normal driving): typically every 7,500 miles (12,000 km) or 12 months, whichever comes first; more frequent changes may be recommended under severe driving conditions.
The above figures are based on the factory specification for the 2019 Ridgeline’s 3.5L V6. Always consult the owner’s manual for your exact vehicle and regional advice, as some markets may have slightly different recommendations or maintenance intervals.
Notes for ensuring accuracy
When you perform an oil change, use the recommended filter and ensure the engine is warm but not hot for easier draining. After filling, check the dipstick to confirm the level is within the proper range, and start the engine to verify there are no leaks.
Why the number matters
Using the correct oil quantity helps protect engine bearings, maintain proper oil pressure, and avoid overfill, which can cause foaming or leaks. For the Ridgeline, sticking to the 5.0-quart specification for a full oil change with a new filter is a reliable standard to follow, complemented by the recommended 0W-20 viscosity in most climates.
Summary
In short, a 2019 Honda Ridgeline requires about 5.0 quarts of engine oil with a filter for a standard oil change. Use the recommended 0W-20 synthetic oil for most conditions, and always verify your specific vehicle’s requirements in the owner's manual or with a dealership to accommodate regional differences and any special maintenance notes.
