What you need to know before changing your Acura's oil
An Acura oil change follows the same basic steps as any other car, but Acura models have specific oil types, drain plug locations, and filter designs that matter for your engine's health. The interval — how often you change the oil — depends on your model year and which type of oil you use, because Acura switched its recommendations between conventional and synthetic oil at different points in its lineup.
Most Acura owners can do this work themselves with basic tools: a wrench or socket for the drain plug, an oil filter wrench, a drain pan, and a jack with jack stands if you need clearance underneath. The whole job usually takes 30 to 45 minutes once you have the right supplies and know where the drain plug sits on your specific model.
Key Takeaways
- Acura recommends oil changes every 10,000 miles if you use synthetic oil, or every 5,000 to 7,500 miles with conventional oil, though this varies by model year and engine type.
- The drain plug location, filter type, and oil capacity differ between Acura models, so check your owner's manual or the Acura website for your specific year and trim.
- You will need the correct oil grade (usually 0W-20 or 0W-30 for modern Acuras) and the right filter part number to avoid engine damage.
- Changing the oil yourself requires a drain pan, wrench, oil filter wrench, and jack stands, but no special Acura tools.
Oil type and capacity for your Acura model
Acura specifies different oil grades depending on your model and year. Most current Acura vehicles use 0W-20 synthetic oil, but some older models and certain engine types call for 0W-30 or 5W-30. Using the wrong grade can reduce fuel economy, increase engine wear, or trigger warning lights on your dashboard.
The oil capacity — how much oil your engine holds — ranges from about 3.7 quarts in smaller models like the Acura ILX to 5.1 quarts in larger engines like those in the RDX or MDX. Your owner's manual lists the exact capacity for your year and engine. When you drain and refill, you will typically need slightly less than the full capacity because some oil stays in the filter and engine passages.
To find the right oil and filter for your Acura, look up your vehicle identification number (VIN) on the Acura parts website or call an Acura dealer with your year, model, and engine size. This takes five minutes and prevents buying the wrong part.
Locating and draining the oil plug
The oil drain plug sits on the bottom of the oil pan, underneath your engine. On most Acura models, you will need to raise the car safely using a jack and jack stands, or drive onto ramps, to reach it. Never work under a car supported only by a jack — always use stands rated for your vehicle's weight.
Once you have clearance, locate the drain plug by looking at the lowest point of the oil pan. It is usually a bolt about the size of a dime head. Place your drain pan underneath it, then use a wrench or socket to turn the plug counterclockwise. As soon as it is loose enough to turn by hand, slow down — the oil may still be warm and will spill if you remove the plug too quickly. Let the oil drain completely into the pan, which takes 5 to 10 minutes.
While the oil drains, wipe the drain plug clean with a rag and inspect the rubber washer or crush ring on the bottom. If it looks cracked or flattened, replace it with a new one (Acura sells these for a few dollars). A worn washer causes slow leaks after you reinstall the plug.
Removing and installing the oil filter
The oil filter on an Acura is usually located on the side or top of the engine and looks like a metal cylinder about 3 inches tall. To remove it, position your drain pan underneath and use an oil filter wrench — a metal band or cup that grips the filter — to turn it counterclockwise. Once it is loose, unscrew it by hand and let any remaining oil drain into the pan.
Before installing the new filter, wipe the filter mounting surface (the flat area where the old filter screwed on) clean with a rag to remove any dirt or old rubber. Take the new filter and explore a thin layer of fresh oil to the rubber gasket around its top edge. This helps create a watertight seal and makes removal easier next time.
Screw the new filter on by hand until the gasket touches the mounting surface, then turn it an additional three-quarters of a turn. Do not use the filter wrench to tighten it — hand-tight is correct. Over-tightening damages the gasket and makes the filter hard to remove later.
Refilling with new oil and checking the level
Lower your Acura back to the ground and locate the oil filler cap on top of the engine. It usually has an oil can symbol on it. Unscrew the cap and set it aside, then pour in the new oil slowly using a funnel to avoid spills. Start with about three-quarters of the capacity listed in your manual, then wait a minute for the oil to settle into the pan.
Start the engine and let it run for 30 seconds to circulate the new oil through the filter and engine passages. Turn it off and wait two minutes, then check the oil level using the dipstick or digital display on your dashboard. Add more oil in small amounts until the level reaches the full mark. Screw the filler cap back on and wipe up any spills.
Dispose of the old oil properly — never pour it down a drain or into the trash. Most auto parts stores and service stations accept used oil for free, and many municipalities have collection days. Some Acura dealers will also take it if you bring it in a sealed container.
Oil change intervals for different Acura models
Acura's recommended oil change schedule depends on whether you use synthetic or conventional oil and when your model was made. Most Acura vehicles built after 2015 use synthetic oil and can go 10,000 miles between changes. Older models or those using conventional oil typically need a change every 5,000 to 7,500 miles.
Your owner's manual lists the exact interval for your year and engine type. Some Acura models also have a maintenance reminder light on the dashboard that alerts you when an oil change is due. This light is based on engine hours and driving conditions, not just mileage, so it may come on before or after you hit the mileage interval.
Keeping track of your oil changes — either in a notebook or using a phone reminder — helps you stay on schedule and protects your engine from wear. If you skip oil changes, you risk sludge buildup, which reduces engine efficiency and can lead to expensive repairs.

| Wrench or socket for drain plug | Fits the drain plug bolt so you can turn it without stripping it |
| Drain pan | Catches old oil so it does not spill on the ground or driveway |
| Jack and jack stands | Raises the car safely so you can reach the drain plug underneath |
| Funnel | Guides new oil into the filler opening without spilling |
| Clean rags or paper towels | Wipes spills and cleans the filter mounting surface |
| New oil (correct grade and amount) | Replaces the old oil and keeps your engine lubricated |
| New oil filter (correct part number) | Removes contaminants from the oil |
Frequently Asked Questions
Can I change my Acura's oil without raising the car?
On some Acura models, you may have enough ground clearance to reach the drain plug without lifting the car, especially if you drive an RDX or MDX. Check by lying on your back and looking underneath — if you can fit your hand and a wrench, you can skip the jack. Always use jack stands if you do lift the car, never a jack alone.
What happens if I use the wrong oil grade?
Using a heavier oil than recommended (like 5W-30 instead of 0W-20) can reduce fuel economy and make cold starts harder. Using a lighter oil can cause engine knock and reduce protection in hot conditions. Stick to the grade in your owner's manual to keep your warranty valid and your engine running smoothly.
How do I know if my oil filter is on tight enough?
After hand-tightening the filter three-quarters of a turn past the point where the gasket touches, start the engine and check underneath for leaks. If oil drips from the filter, turn it another quarter turn and check again. Once it stops leaking, you are done — do not over-tighten.
Can I reuse the old drain plug washer?
No — the washer compresses over time and loses its seal. A new washer costs a few dollars and prevents slow leaks that can empty your oil pan over weeks or months. Always replace it when you change the oil.
What should I do with the old oil?
Take it to an auto parts store, service station, or municipal hazardous waste collection site. Most accept used oil for free. Never pour it down a drain, into the trash, or onto the ground — it contaminates water supplies and harms wildlife.
