The Ridgeline’s 2008 model uses about 5.5 quarts of engine oil when performing an oil change with a new filter.
The 2008 Ridgeline is powered by Honda’s 3.5-liter V6 (engine code J35A). Official maintenance data lists an engine oil capacity of 5.5 quarts (approximately 5.2 liters) with the oil filter. Honda typically recommends 5W-20 oil for this engine in most regions, though you should confirm the exact grade in your owner's manual for your climate. The 5.5-quart figure is the standard capacity when changing the oil with a new filter; variances can occur if the filter isn’t replaced or if different oil grades are used, but 5.5 quarts is the reliable baseline.
Oil capacity by the numbers

Practical notes for Ridgeline owners
Oil grade and service intervals
Use the recommended 5W-20 motor oil for the 3.5L V6 in the Ridgeline. Standard service intervals typically range around every 5,000 miles under normal driving conditions, with synthetic options potentially extending that interval. Always follow the maintenance schedule in your owner’s manual, as conditions like extreme temperatures, heavy towing, and frequent short trips can shorten the interval.
How to verify the oil level after a fill
After adding oil, wait a few minutes for it to settle, then check the level with the dipstick. Ensure you reach the full mark without overfilling, as overfilling can cause oil foaming and engine issues. If you’ve just changed the filter, confirm you’ve added the full 5.5 quarts to reach the correct level.
Summary
The official specification for a 2008 Honda Ridgeline with the 3.5L V6 is an engine oil capacity of 5.5 quarts with a new filter, using 5W-20 oil in most climates. This figure serves as the reliable baseline for a complete oil change; always consult your owner’s manual for any region-specific recommendations and verify oil quantity after filling.
