2018 Honda Accord engine oil capacity

If you’re doing your own oil change, you’ll need to have enough engine oil on hand to get the job done. Having too much or too little oil circulating through your engine could cause expensive engine damage.
Even within the same make and model year, vehicles can come with different engine types that will have different oil capacities. 
So, how much engine oil does your 2018 Honda Accord 1.5L need? It’s not 1.5 liters—that’s your engine’s displacement, which is the collective volume of all its cylinders. The 2018 Honda Accord 1.5L engine oil capacity is actually 3.7 quarts, or 3.5 liters.

What kind of oil does a 2018 Honda Accord need?

Just as important as knowing your 2018 Honda Accord’s 1.5L engine oil capacity is knowing what type of oil it needs.
The 2018 Honda Accord owner’s manual recommends using premium grade 0W-20 detergent oil.
Here’s a breakdown of what that means. The “0” refers to the engine oil’s viscosity or thickness at colder temperatures before engine startup. The “20” refers to the oil’s viscosity near engine operating temperatures, around 212°F.
Honda recommends Genuine Honda Motor Oil 0W-20 as a first choice, but what’s most important is that your engine oil has the correct viscosity grade and an American Petroleum Institute (API) certification seal on the label. Synthetic oil is okay to use, too, as long as it also has the same viscosity grade.

How often to change oil on a 2018 Honda Accord

Generally, it’s recommended that you change conventional oil every 3,000 to 5,000 miles, but if you’re using synthetic oil, you may be able to go as long as 7,500 to 10,000 miles before needing an oil change. If you haven’t been driving frequently, it’s usually a good idea to still change your engine oil at least every six months.
Since when you should change your oil can vary so much, it’s important to regularly check your engine oil. Use your dipstick to make sure it’s at the proper level, and check your oil levels once a month or whenever you’re refueling.
If it’s time to change your 2018 Honda Accord 1.5L engine oil, you may notice any of the following:
  • Dark brown or black oil (fresh engine oil is a lighter brown)
  • Engine oil has a grainy texture
  • Strange engine noises
  • Burning, oil, or smoke scents coming from the engine
  • Worsened engine performance

How to change your oil and oil filter

Now that you know your 2018 Honda Accord 1.5L engine oil capacity and type, it’s time to get ready to
change your oil
Here are some items you’ll need to get the job done: 
  • Socket wrench
  • Screwdriver
  • Oil filter wrench (the tool used to remove oil filters)
  • Drain pan
  • New oil filter
  • Fresh engine oil
  • New washer for the drain bolt
  • Towel(s) for cleanup
To get started, let your engine run for just a few minutes—this will help warm up the oil and make it easier to drain. Then, head to the front of your vehicle, prop open your hood, and proceed:
  • Remove your oil fill cap
  • Underneath your vehicle, use your screwdriver to remove the protective panel that will give you access to the drain bolt
  • Remove the drain bolt and washer, allowing the oil to empty into the drain pan
  • While the oil continues to drain, remove the other protective panel to remove the old oil filter and install the new oil filter
  • Replace the oil drain bolt using a new washer and tighten it to 30 lb-ft
  • Once the oil’s finished draining, replace the protective panels 
  • Refill the engine oil to the proper level and replace the oil fill cap
After changing your oil, it’s a good idea to turn on your car and let your engine run for about 30 seconds before you check the oil level. This will give you a more accurate measurement, and you’ll be able to top it off if necessary.
Next, you can turn your engine back on and let it run for another few minutes, checking around for leaks. After your engine has cooled off, you can use your dipstick to check the oil level again, topping it off if you need to.
Don’t forget to properly dispose of your old engine oil—it’s a hazardous material! Most cities have drop-off locations to recycle it as do certain auto shops and dealerships.
