The 2015 Honda Accord LX with the 2.4-liter engine takes 4.5 quarts of engine oil during an oil change that includes a new filter.
In this article, we explain the specific capacity for the LX, note how it differs from other trims, and outline the recommended oil grade and maintenance context for this model year.
Oil capacity for the 2015 Accord LX
The LX is equipped with a 2.4L inline-4 engine. The official oil capacity with a new filter is 4.5 quarts. Honda generally recommends synthetic 0W-20 oil for this engine, with 5W-20 being an acceptable alternative in certain climates as specified in the owner’s manual.
Engine variants in the 2015 lineup
Other trims in the 2015 Accord lineup use a different engine. Models with the 3.5L V6 (found in higher trims) have a larger oil capacity, typically around 5.7 quarts. This means the 4.5-quart figure applies specifically to the 2.4L LX/EX/Navi configurations, not the V6-equipped versions.
Practical notes for owners
Always confirm the exact capacity and oil specification in your owner’s manual or on the oil fill label under the hood. Use the recommended oil grade (0W-20 as the primary option) and ensure the engine is properly filled to the correct level after an oil change.
Summary
For the 2015 Honda Accord LX, plan for about 4.5 quarts of engine oil with a new filter, using 0W-20 oil (or 5W-20 as allowed by the manual). If your Accord has the 3.5L V6 engine, the capacity differs (approximately 5.7 quarts).
