Keeping your 2013 Lexus RX 350 running smoothly for years to come hinges on a few key maintenance habits, and perhaps none is more critical than using the correct oil. This luxurious and reliable SUV is engineered for performance and longevity, but its heart—the 3.5-liter V6 engine—demands specific lubrication to perform at its best. Using the wrong oil can lead to reduced efficiency, increased wear, and potentially costly repairs down the line. That’s why having a clear and definitive resource on the proper 2013 Lexus RX 350 oil type is so important for every owner.
Whether you’re a seasoned DIY enthusiast or a new owner who simply wants to be informed when talking to a mechanic, knowing the specifications for your vehicle is empowering. This guide is designed to take the guesswork out of your next oil change. We’ll cover everything from the recommended oil grade and viscosity to capacity and filter choices, providing you with a true 2013 Lexus RX 350 Oil Type: A Complete Guide to ensure your luxury SUV gets the premium care it deserves.
What is the Recommended Oil for a 2013 Lexus RX 350?
For the 2013 Lexus RX 350, the manufacturer provides a clear recommendation to ensure optimal engine performance and protection. The preferred oil is 0W-20 synthetic. This is a full-synthetic motor oil that is designed to flow easily at low temperatures for better cold-start protection while maintaining its stability and protective qualities at high engine temperatures.
Lexus specifically states that using 0W-20 synthetic oil contributes to improved fuel economy. In some cases, if 0W-20 is not available, the owner’s manual indicates that 5W-20 can be used as a temporary substitute. However, it is strongly advised to revert to 0W-20 at the next oil change. It is also worth noting that newer formulations of synthetic oil are a significant upgrade from conventional oils and are essential for meeting the engine’s precise engineering requirements.
How Much Oil Does the 2013 RX 350 Need?
Knowing the oil capacity is just as important as knowing the correct type. For a standard oil and filter change on the 2013 RX 350’s 3.5L V6 engine, you will need approximately 6.4 quarts (or 6.1 liters) of oil. It is always a good practice to double-check the oil level with the dipstick after the change and after the engine has run for a moment and settled. The goal is to have the oil level between the two marks on the dipstick, not overfilled.
If you are performing a more extensive service where the engine has been completely drained or the oil cooler has been removed, the total capacity may be slightly higher, but for nearly all home and quick-lube oil changes, the 6.4-quart figure is your guide.
Choosing the Right Oil Filter
An oil change is only as good as the filter you use. The oil filter plays a vital role in trapping contaminants and metal particles that can circulate through your engine and cause wear. For your 2013 RX 350, it is crucial to select a high-quality filter that meets Lexus’s specifications.
You have a few excellent options. The obvious choice is the genuine Lexus oil filter, which is designed specifically for your vehicle. High-quality alternatives from brands like Toyota, PurolatorONE, Mobil 1, or Fram Ultra Synthetic are also reliable choices. When selecting a filter, look for one with a strong anti-drain back valve to prevent oil from draining out of the filter when the engine is off, ensuring immediate lubrication upon startup.
Why Sticking with Synthetic 0W-20 is So Important
You might wonder why the specification for this oil is so precise. The 2013 RX 350’s engine is built with very tight tolerances between its moving parts. The low viscosity of 0W-20 oil allows it to flow quickly and efficiently into these narrow spaces, especially during a cold start when most engine wear occurs. This provides instant protection for critical components like the camshafts and piston rings.
Furthermore, full-synthetic oil is more resistant to breaking down under high heat and stress. This means it maintains its protective properties for longer than conventional oil, which is a key reason why Lexus recommends longer oil change intervals when using it. Using a heavier oil can lead to increased engine drag, reduced fuel economy, and in the long term, insufficient lubrication in the finely-tuned engine.
Your 2013 Lexus RX 350 Oil Type: A Complete Guide to the Change Process
If you’re planning to change the oil yourself, having a clear plan makes the job simple. First, gather your supplies: 6-7 quarts of 0W-20 full-synthetic oil, a new oil filter, a new drain plug gasket (a small but important part), a wrench set, an oil filter wrench, a funnel, a drain pan, and gloves.
Ensure the engine is warm but not hot to help the oil drain completely. Safely lift and support the vehicle, then locate the drain plug and oil filter on the underside of the engine. Place your drain pan underneath, remove the drain plug, and allow the old oil to drain fully. Once drained, replace the drain plug with its new gasket, tightening it to specification—do not over-tighten. Next, remove the old filter, lubricate the gasket on the new filter with a bit of fresh oil, and install it by hand. Finally, refill the engine with the new 0W-20 oil through the oil filler cap under the hood, check for leaks, and verify the oil level with the dipstick.
How Often Should You Change the Oil?
Lexus originally recommended an oil change interval of every 10,000 miles or 12 months under normal driving conditions when using the specified 0W-20 synthetic oil. However, “normal” driving is often a misnomer. If your driving habits include frequent short trips, extreme temperatures, stop-and-go traffic, or towing, these are considered severe driving conditions.
For most owners, a more conservative interval of 5,000 to 7,500 miles is a wise and proactive approach to engine maintenance. It is always better to change the oil a little too often than not often enough. The vehicle’s Maintenance Reminder light is also a good guide, but understanding your own driving style will help you make the best decision for your SUV’s longevity.
Final Thoughts on Keeping Your Engine Protected
Caring for your 2013 Lexus RX 350 doesn’t have to be complicated. By simply adhering to the core recommendation of using 0W-20 full-synthetic oil, replacing the oil and filter at appropriate intervals, and always checking your work, you are providing your engine with the best possible protection. This straightforward practice is one of the most effective ways to preserve the smooth, quiet, and powerful performance that defines the Lexus driving experience, ensuring your reliable SUV continues to serve you well for many miles to come.
