Lexus RX 350 Oil Type & Capacity (2010-2026): Every Engine, Year by Year
Across three generations, the Lexus RX has used six different engines — and they do not all take the same oil, the same amount of oil, or even the same style of filter. The 3.5-liter V6 carried the RX from 2010 through 2022. In 2023, the fifth-generation RX replaced it entirely: the gas RX 350 moved to a 2.4-liter turbocharged inline-4, and the hybrids moved to a 2.5-liter four-cylinder that calls for a thinner grade than any RX before it. Two mistakes account for most of the confusion at oil-change time: assuming a hybrid RX always takes 0W-16 (only the 2023-and-newer ones do), and buying a spin-on filter for a V6 that uses a cartridge. This guide sorts it out by engine.
Lexus RX Oil Type and Capacity at a Glance (2010–2026)
Your RX’s oil specification is determined by its engine, not its trim level. Find your engine below — the table is organized by engine family, then by model year. Every capacity shown is a drain-and-refill quantity with a new filter installed.
| Engine | Model years | RX model(s) | Recommended oil | Capacity with filter | Oil filter |
|---|---|---|---|---|---|
| 2GR-FE — 3.5L V6 | 2010–2015 | RX 350 | SAE 0W-20 full synthetic | 6.4 quarts (6.1 liters) | Cartridge element; Genuine Lexus 04152-YZZA1 |
| 2GR-FKS — 3.5L V6 | 2016–2022 | RX 350; RX 350L (2018–2022) | SAE 0W-20 full synthetic | 5.7 quarts (5.4 liters); 5.8 quarts (5.5 liters) with towing package | Cartridge element; Genuine Lexus 04152-YZZA1 |
| 2GR-FXE — 3.5L V6 hybrid | 2010–2015 | RX 450h | SAE 0W-20 full synthetic | 6.4 quarts (6.1 liters) | Cartridge element; Genuine Lexus 04152-YZZA1 |

| T24A-FTS — 2.4L turbocharged inline-4 hybrid | 2023–2026 | RX 500h | SAE 0W-20 full synthetic | 5.6 quarts (5.3 liters) | Spin-on canister; Genuine Lexus 90915-YZZN1 |
A proper oil change always includes a new filter, so plan for the full capacity above. Then confirm the final level on the dipstick after running the engine briefly. Overfilling is as harmful as underfilling. Too much oil lets the crankshaft whip air into it. That foamed, aerated oil cannot be pumped effectively. The result is lower oil pressure, poor lubrication of critical components, and stress on engine seals. Underfilling risks oil starvation and heat buildup.
For a genuine-parts oil change performed to factory spec, you can schedule a professional oil change with our certified technicians. You can also confirm the exact grade and capacity for your specific vehicle in the Lexus Owner’s Manual for your model year.
Oil type, capacity, filter, viscosity, and interval figures are based on Lexus owner’s-manual, service-bulletin, and parts-catalog specifications for the third-, fourth-, and fifth-generation RX. Capacities are reference drain-and-refill quantities — the dipstick is the final authority on fill level. Vehicles built with an engine oil cooler or towing package may take slightly more. Always confirm the exact spec for your VIN in your owner’s manual or with our service team.
Which Engine Is in Your RX?
Trim badges will not tell you what oil to buy, but the generation and model name will. Here is how the lineup breaks down.
- Third generation (2010–2015): RX 350 with the 3.5-liter V6 (2GR-FE), and RX 450h with the Atkinson-cycle hybrid version of that V6 (2GR-FXE). Both take 0W-20.
- Fourth generation (2016–2022): RX 350 and the long-wheelbase RX 350L with an updated 3.5-liter V6 (2GR-FKS), plus RX 450h and RX 450hL with its hybrid counterpart (2GR-FXS). All four take 0W-20.
- Fifth generation (2023–2026): RX 350 with the 2.4-liter turbo four (T24A-FTS), RX 500h with a performance hybrid version of that same turbo four, RX 350h with the 2.5-liter hybrid four (A25A-FXS), and — added for 2024 — the RX 450h+ plug-in hybrid using the same 2.5-liter engine. The two turbo models take 0W-20; the two 2.5-liter hybrids take 0W-16.
The pattern worth remembering: a hybrid badge does not automatically mean 0W-16. It means 0W-16 only if your RX is a 2023-or-newer RX 350h or RX 450h+.
The 3.5L V6 (2010–2022): 0W-20 and a Cartridge Filter
Every US-market RX built from 2010 through 2022 — gas or hybrid, standard or long-wheelbase — calls for SAE 0W-20 full synthetic. If 0W-20 is genuinely unavailable, Lexus permits SAE 5W-20 as a temporary substitute, to be drained and replaced with 0W-20 at the next oil change.
Why 0W-20 came with a longer interval
Beginning with the 2010 model year, Lexus transitioned its lineup to 0W-20 synthetic oil for reduced friction, better fuel economy, and less waste oil. The RX 350 and RX 450h were among the models where 0W-20 was made mandatory rather than optional — and only those mandatory-0W-20 models were approved for the extended 10,000-mile oil change interval. Vehicles where 0W-20 was merely an alternative to a heavier grade kept a 5,000-mile interval. That is why a 2010 RX 350 goes 10,000 miles between changes while some other Lexus models of the same year did not.
Capacity dropped when the engine was updated
The 2010–2015 V6 holds 6.4 quarts with a filter change. The updated 2016–2022 V6 holds noticeably less — 5.7 quarts, or 5.8 quarts on vehicles equipped with the towing package, which adds an engine oil cooler circuit. Owners cross-referencing an older guide routinely overfill a fourth-generation RX by most of a quart for exactly this reason.
These engines use a cartridge filter, not a spin-on
All 2010–2022 RX V6 models use a replaceable cartridge filter element, Genuine Lexus 04152-YZZA1, seated inside a threaded plastic housing cap (15620-31060). The cap has a drain plug that should be removed first to let the housing empty before the cap comes off, and the cap’s O-ring should be replaced and lightly oiled at every service. These caps are known to crack if over-torqued or removed with the wrong tool, so a correctly sized cap wrench matters.
The 2.4L Turbo (2023–2026): RX 350 and RX 500h
Lexus designates SAE 0W-20 full synthetic as the primary viscosity grade for the turbocharged four-cylinder, in both the gas RX 350 and the performance-hybrid RX 500h. Full synthetic is not optional here. The turbocharger, the variable valve timing, and the engine’s oil-pressure tolerances are all engineered around a thin, thermally stable synthetic. That oil has to flow freely to cool and lubricate the turbo bearings. Note too that the turbocharger housing and its internal parts are covered under the Lexus Powertrain Warranty. Protecting them with the correct oil has real financial consequences.
What certification should the oil carry?
To meet factory standards, the oil should carry ILSAC GF-6A certification (the older GF-5 standard is also acceptable) and display the API “Starburst” service mark on the container. Lexus moved to the GF-6A specification beginning with the 2022 model year. These standards ensure the oil contains additives that resist low-speed pre-ignition, protect the timing chain, and stand up to the heat of a small-displacement, high-output turbo engine.
What if 0W-20 is unavailable?
If 0W-20 is genuinely unavailable, Lexus allows SAE 5W-20 full synthetic as a temporary substitute — but it should be drained and replaced with 0W-20 at the very next oil change.
The 2.5L Hybrids (2023–2026): RX 350h and RX 450h+
The RX 350h and the RX 450h+ plug-in hybrid share a 2.5-liter hybrid four-cylinder that calls for SAE 0W-16 full synthetic — a thinner grade than the turbo’s 0W-20, and thinner than anything the older V6 hybrids used. A hybrid’s gas engine cycles on and off repeatedly during a single drive. The oil has to reach bearing surfaces almost immediately on each restart. The lower viscosity supports that rapid circulation. It also supports the efficiency targets the hybrid system is built around. Two details are easy to get wrong.
The oil certification is different
0W-16 oils are certified to ILSAC GF-6B and carry the API “Shield” mark, not the “Starburst” used on GF-6A oils. GF-6B is not backward compatible with GF-6A — these are separate standards, and a GF-6A 0W-20 bottle is not a GF-6B product. If you drive an RX 350h or RX 450h+, this is the single most important detail on this page.
0W-20 is an approved fallback, not a mistake
If 0W-16 is unavailable, Lexus permits SAE 0W-20 in these hybrids, replaced with 0W-16 at the next scheduled service. Running 0W-20 long-term will reduce the efficiency the hybrid was calibrated for, but a single fill is not a failure condition.
Older RX hybrids do not take 0W-16
This is where owners of a 2010–2022 RX 450h or RX 450hL get tripped up. Those vehicles use the 3.5-liter V6 hybrid system and take 0W-20, not 0W-16, and they hold considerably more oil — 6.4 quarts on 2010–2015 models and 5.7 quarts on 2016–2022 models. Filling a 2018 RX 450h with 4.5 quarts of 0W-16 would leave it more than a quart low on the wrong grade.
The filter is shared across the fifth generation
All four fifth-generation powertrains — RX 350, RX 350h, RX 450h+, and RX 500h — use Genuine Lexus spin-on filter 90915-YZZN1, per the Lexus parts catalog. The oil differs; the filter does not.
How Often Should You Change the Oil?
Lexus publishes two oil-and-filter intervals for the RX in its 2026 RX 350 Warranty and Services Guide, and which one applies to you depends on how you drive. The same two-tier structure has applied to the RX since the 2010 transition to 0W-20.
| Driving conditions | Engine oil and filter replacement interval |
|---|---|
| Normal driving | Every 12 months or 10,000 miles, or when the oil maintenance reminder appears — whichever comes first |
| Special (severe) operating conditions | Every 6 months or 5,000 miles, regardless of the oil used |
Note that even on the 10,000-mile schedule, the 5,000-mile service visit has not been eliminated. Tire rotation and fluid level checks — including engine oil — still happen at 5,000-mile intervals.
What counts as a special operating condition?
Lexus defines these narrowly. The shorter interval applies if the majority of your driving falls into one of these categories:
- Driving mainly on dirt or dusty roads, including roads treated with salt
- Towing a trailer, using a car-top carrier, or carrying heavy loads (properly equipped RX models are generally rated to tow up to 3,500 pounds)
- Extensive idling or low-speed driving over long distances, such as commercial, taxi, or delivery use
- Repeated short trips in cold weather, where the engine never reaches full operating temperature
If you only occasionally drive under these conditions, Lexus notes the additional services are not necessary. The hybrids follow the same 12-month, 10,000-mile normal schedule; a hybrid’s engine may run less, but oil still absorbs moisture and combustion byproducts over time, and Lexus does not extend the interval for hybrid or plug-in hybrid models.
Check the oil level monthly
Separate from scheduled service, Lexus recommends checking the engine oil level with the dipstick at least once every 30 days. The manufacturer is direct about why. Failing to check the oil and replace it on schedule can cause oil starvation or oil gelling. That can severely damage the engine. Those repairs are not covered by the New Vehicle Limited Warranty. This matters more, not less, on higher-mileage third- and fourth-generation V6 models, where gradual oil consumption between changes is common enough to be worth watching.
How service records affect your warranty
New Lexus vehicles carry a 48-month/50,000-mile basic warranty and a 72-month/70,000-mile powertrain warranty. Lexus will not deny a warranty claim solely because you cannot produce maintenance records, and you are free to have maintenance performed wherever you choose. What is not covered is damage caused by lack of proper maintenance. Nor is damage caused by using fluids other than those specified in the Owner’s Manual. That is exactly why the correct oil grade matters. Keeping dated service records simply makes it easy to show the work was done.
Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.

Servicing Your RX: What to Know
The filter style changed with the fifth generation. The 2023-and-newer RX uses a spin-on oil filter — a self-contained canister that threads onto the engine. Every 2010–2022 RX uses a cartridge element seated in a reusable housing. Neither approach is better; they simply require different parts and different technique, and cross-referencing the wrong generation’s guide is a frequent source of confusion.
On spin-on filters, lightly coat the rubber gasket with fresh oil before installing, then tighten to specification so it seats without leaking. On cartridge housings, drain the housing through its plug first, replace the O-ring, and avoid over-torquing the plastic cap. In both cases it is good practice to replace the oil drain-plug crush washer at every service to prevent slow leaks over time. Our factory-trained technicians handle all of this with genuine Lexus parts as a matter of course — including on older RX models, which we still see regularly from Temecula and Menifee owners who have kept them well past 100,000 miles.

Quick Answers Before You Visit
What oil does a 2010–2015 Lexus RX 350 take?
SAE 0W-20 full synthetic, 6.4 quarts with a filter change. SAE 5W-20 is permitted only as a temporary substitute if 0W-20 is unavailable. The same specification applies to the 2010–2015 RX 450h hybrid.
Why does my 2018 RX 350 take less oil than my old 2012 RX 350?
The 3.5-liter V6 was updated for the 2016 model year. The earlier engine holds 6.4 quarts with a filter; the updated engine holds 5.7 quarts, or 5.8 quarts with the towing package. Using the older figure on a newer RX will overfill it.
Does my Lexus RX hybrid take 0W-16?
Only if it is a 2023-or-newer RX 350h or a 2024-or-newer RX 450h+. The 2010–2022 RX 450h and RX 450hL use the 3.5-liter V6 hybrid system and take SAE 0W-20.
Can I put 0W-20 in my RX 350h instead of 0W-16?
Yes, temporarily. Lexus lists SAE 0W-20 as an acceptable substitute for the 2.5-liter hybrids when 0W-16 is unavailable, but it should be replaced with 0W-16 at the next scheduled oil change to restore the engine’s designed efficiency.
Can I use 5W-30 synthetic in the Lexus RX 350?
No. The recommended viscosity is SAE 0W-20 for every RX 350 from 2010 through 2026. SAE 5W-20 full synthetic may be used temporarily only if 0W-20 is completely unavailable, and it should be replaced with 0W-20 at the very next service.
Does the RX 500h take the same oil as the RX 350?
Yes. The RX 500h uses a hybrid version of the same 2.4-liter turbocharged engine as the RX 350, and both call for SAE 0W-20 full synthetic with a capacity of 5.6 quarts including the filter.
What is the OEM oil filter part number for my RX?
It depends on the generation. 2010–2022 models use cartridge element 04152-YZZA1 in housing cap 15620-31060. 2023–2026 models use spin-on filter 90915-YZZN1. Lexus states that warranty coverage is not dependent on using any particular brand of replacement part, though it recommends Genuine Lexus Parts, and damage caused by improper maintenance is not covered.
What happens if the oil is slightly overfilled during a DIY oil change?
Overfilling lets the crankshaft whip air into the oil, creating foam. That aerated oil cannot be pumped effectively, which drops oil pressure, reduces lubrication of critical parts, and can damage engine seals. On turbocharged models it also compromises the oil feed to the turbocharger bearings.
How often should I check my oil level between services?
Lexus recommends checking the engine oil level with the dipstick at least once every 30 days, along with a visual check of coolant, brake fluid, washer fluid, and tire pressure.
Does the Lexus RX 350’s 2.4L turbo require premium fuel?
Yes. The owner’s manual for the 2023-and-newer RX 350 specifies premium unleaded gasoline rated 91 octane or higher. Using lower-octane fuel can cause persistent engine knock and, at worst, engine damage.
How does the oil change interval change if I tow with my RX?
Towing a trailer, using a car-top carrier, or carrying heavy loads counts as a special operating condition. That shortens the oil-and-filter interval from 12 months or 10,000 miles to 6 months or 5,000 miles, regardless of the oil used.
