2006 Acura TL engine oil capacity

Before you rush out to buy supplies for an
oil and filter change
, you’ve got to know how much oil a 2006 Acura TL needs! The TL’s 3.2-liter V6 engine has a 4.5-quart or 4.3-liter oil capacity.
Don’t get the oil capacity mixed up with the
engine displacement
—the 3.2-liter volume the engine’s cylinders take up. Engine displacement is not the same as oil capacity, so the numbers aren’t interchangeable.

What kind of oil does a 2006 Acura TL need?

If you’ve spent any time in the motor oil aisle, you know there are an overwhelming number of options. Fortunately,
makes it simple and recommends buying Honda premium-grade 5W-20 engine oil for your 2006 TL.
You can buy conventional or synthetic oil if you can’t get your hands on Honda premium, but it has to have the same 5W-20 viscosity. Don’t worry about buying products with engine oil additives. Your Acura engine doesn’t need them!
We'll give you a quick rundown if you’re curious about what those numbers mean. The numbers in the oil grade show you the oil’s viscosity, which is basically how thick it is. The “W” means “winter,” and the 5 tells you that the oil stays thin at a chilly 0°F. The 20 shows that the oil is also pretty thin even when the engine temperature reaches 212°F.
Simply put, the right oil helps your Acura start in cold temperatures, improves performance, and protects the engine from damage. This is why it’s so important to get the correct oil grade!

How often to change oil on a 2006 Acura TL

Acura advises changing your oil every 3,000 to 5,000 miles. This is a pretty big range when you think about it! 
To help you get a better idea of whether you need to change the oil, check your oil frequently. You could do it once a month or every other time you get gas. Here are some signs that it’s time for an oil change:
  • The oil looks dark brown or black instead of light brown or amber.
  • The oil feels coarse or sandy when you rub it between your fingers. 
  • You hear strange sounds coming from the engine.
  • You smell oil, smoke, or burning.
  • Your Acura handles differently.

How to change your oil and oil filter

Once it’s time, you’ll need a socket wrench, a drain pan, and a filter wrench, which makes it easier to remove the old oil filter. Remember to pick up a replacement filter when you buy the five-quart bottle of premium 5W-20 engine oil. Oh, and some old cloths or rags are handy because changing oil is a messy job!
Turn on your Acura’s engine and run it for a few minutes so the oil warms up and is easier to drain. Then, switch it off,
open the hood of your car
, and follow these simple steps:
  • Unscrew the oil fill cap and set it aside.
  • Slide under the engine and remove the oil drain bolt and washer.
  • Drain the old oil into a drain pan and take out the old filter, too.
  • Put in the new filter.
  • Replace the oil drain bolt with a new washer and tighten it to 29 lb-ft. 
  • Replace the engine oil with the new oil and screw on the oil fill cap.
Next, switch on the engine and run it for around 30 seconds to give the filter time to soak up some of the new oil. The
oil pressure indicator light
should turn off within five seconds. If it doesn’t, turn off the engine and check your work. Now is also a good time to check for leaks.
You should also see if you added enough oil. Pull out the dipstick to see if the oil is at the recommended level. If it’s too low, just top it off.
Don’t forget to clean up before you drive off. You can’t simply pour the old oil onto the ground or throw it in the trash. Put it into a sealed container and take it to your local recycling center, where they’ll dispose of it safely.
