2010 Lexus RX 350 engine oil capacity

First things first, the 2010 Lexus RX 350 oil capacity is 6.4 qt or 6.1 L with an oil filter replacement. It is recommended to change the filter with every oil change, however, if you opt against it, expect to add about 0.4 qt less oil. 
It is important not to confuse the engine oil capacity with the engine displacement. The 2010 RX 350 is powered by a 3.5-liter V6 engine. The “3.5-liters” here refers to the volume of the engine’s pistons and is not the same as the oil capacity.

What kind of oil does a 2010 Lexus RX 350 need?

Not all engine oils are created equal and it is important to stick with the manufacturer’s recommendation to ensure optimal engine health and performance. Lexus recommends using
Toyota Genuine 0W-20 motor oil
, or equivalent in your 2010 RX 350. Lexus also has specific oil grade recommendations, suggesting an ILSAC oil.
Let’s decode this recommendation real quick. First, ILSAC is just a committee that sets oil standards. ILSAC oil is held to a higher quality standard than many other oils. 
Next, let’s talk about viscosity. “0W-20” is the viscosity rating of the engine oil. The “0W” tells you the viscosity in cold temperatures (measured at 0°F). 0W oils are low viscosity in cold conditions, which is most notable when trying to start a cold engine. The second number–the “20” in this case–is the viscosity at normal operating temperatures of 212°F. 
So, a 0W-20 is a low viscosity oil across a wide temperature range, which ultimately means less wear and tear on your engine.

How often to change the oil on a 2010 Lexus RX 350

Lexus doesn’t offer a specific change interval in their owner’s manual, however, there are some generally accepted rules of thumb to help you decide when to replace your oil.
If you use conventional oil, then 3,000 to 5,000 miles or every six months is the typically recommended period between oil changes. One of the benefits, though, of using synthetic oil is that it tends to have a longer lifespan. Synthetic oils can typically last for 7,500 to 10,000 miles between changes, sometimes longer.
The best advice we can give is actually to check your oil every month or so. This way you can look for signs of dirty oil and decide for yourself if it is time for an oil change. Here are the most common signs that your oil might be past its prime:
  • Oil that is black or dark brown. Clean oil should be amber or light brown and transparent
  • Oil that feels coarse or gritty
  • Weird sounds or smells–especially smells of burning, smoke, or oil coming from your engine
  • Loss of engine performance, like a reduction in power or fuel efficiency
  • The check engine or oil light turning on

How to change your oil and oil filter

If you’ve decided that it’s time for an oil change and that you want to do it yourself, then it's time to collect your
car tools and supplies
. You’ll need a socket wrench, a drain pan, a filter wrench, a replacement oil filter, and 6.4 qt of high-quality 0W-20 motor oil. 
Start by running your engine for a few minutes to bring it up to the normal operating temperature. This will help the oil flow better. Once your engine is warm, shut it off, pop the hood, and follow these steps:
  • Remove the oil fill cap
  • Position the drain pan under the engine and remove the oil drain bolt and washer
  • Remove the old oil filter
  • Let the oil drain completely
  • Install the new filter 
  • Replace the oil drain bolt with a new washer, and tighten it to 30 lb-ft
  • Refill the engine with fresh oil
  • Check the fill level and replace the engine fill cap
  • Run the engine for a few minutes and check for any leaks
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.
The final step is an important one: dispose of the oil responsibly. Don’t just toss your old oil into the gutter or the trash. Put it into a sealed container and take it to a nearby recycling center.
