How many quarts of oil does a 2014 Acura RLX take?
The 2014 Acura RLX typically requires about 5 quarts of engine oil when changing with a new filter. This is the standard capacity for the 3.7-liter V6 used in that model year.
Specifically, the RLX uses a 3.7-liter V6 and generally calls for synthetic oil (commonly 0W-20). The official capacity is around 5 quarts with the filter installed. If you drain and refill without replacing the filter, you’ll usually use about 4.7 quarts. Always verify the level with the dipstick after an oil change and follow the owner’s manual for exact guidance on oil type and interval.
Official oil capacity and recommendations
The following details summarize the official oil capacity and recommended oil type for the 2014 RLX.
- Oil capacity (with new filter): approximately 5 quarts
- Oil capacity (without filter): approximately 4.7 quarts
- Recommended oil type: synthetic 0W-20 (check the owner's manual for your climate and driving conditions)
In summary, plan for about 5 quarts of engine oil when performing a full change with a new filter, and adjust slightly if you do not replace the filter.
Oil-change steps for the RLX
Below is a practical, high-level guide to performing an oil change on the 2014 RLX, including how to arrive at the correct final oil level.
- Prepare the vehicle: gather the correct oil type (0W-20 synthetic), a new oil filter, a drain pan, a socket for the drain plug, and a funnel.
- Warm the engine briefly: run the engine for a few minutes to warm the oil so it drains more completely.
- Lift the car safely: use ramps or a jack and stands to gain access to the drain plug and filter.
- Drain the old oil: place the drain pan beneath the oil pan and remove the drain plug to drain the oil completely.
- Remove and replace the filter: unscrew the old filter, lubricate the new filter’s gasket with a touch of new oil, and install the new filter hand-tight, then give it a final snug with a filter wrench if needed.
- Refill with new oil: install roughly 4.7–5.0 quarts of 0W-20 synthetic (depending on whether you replaced the filter and your exact engine configuration) through the dipstick tube using a funnel.
- Check for leaks and recheck level: start the engine, run for a minute, turn off, wait a few minutes, and check the oil level with the dipstick. Add more oil as needed to reach the Full mark.
After performing an oil change, verify the level and look for any leaks around the drain plug and filter to ensure a proper seal.
Post-change verification
With the engine off and cooled, recheck the oil level using the dipstick and confirm there are no leaks. If the level is between the minimum and maximum marks, you’re within spec. Reset the oil life monitor if your vehicle is equipped with one.
Summary
The 2014 Acura RLX takes about 5 quarts of engine oil when changing with a new filter, with a roughly 4.7-quart figure if the filter isn’t replaced. Use a synthetic 0W-20 (as advised by the owner’s manual), and always confirm the final level on the dipstick after a change.
