Lexus TX Oil Type & Capacity: The Complete 2024–2026 Guide
The Lexus TX is offered with three distinct powertrains across the 2024–2026 model years, and each one has its own lubrication requirements. Whether you drive the gas-only TX 350, the performance-focused TX 500h F SPORT Performance, or the TX 550h+ plug-in hybrid, using the correct oil type and capacity is the foundation of long-term engine health. Below is a clear, powertrain-by-powertrain breakdown so you know exactly what your TX needs.
Lexus TX Oil Specs at a Glance (2024–2026)
| Model | Engine | Oil Type | Capacity (with filter) |
|---|---|---|---|
| TX 350 | 2.4L Turbo I4 (T24A-FTS) | SAE 0W-20 full synthetic | Approx. 5.6 quarts |
| TX 500h F SPORT Performance | 2.4L Turbo I4 Hybrid (T24A-FTS) | SAE 0W-20 full synthetic | Approx. 5.6 quarts |
| TX 550h+ Plug-in Hybrid | 3.5L V6 PHEV (2GR-FXS) | SAE 0W-20 synthetic | See owner’s manual — differs from the 2.4L engines |
TX 350 Oil Type & Capacity (2.4L Turbo)
The TX 350 uses a 2.4-liter turbocharged inline-four engine (engine code T24A-FTS). For the 2024 through 2026 model years, Lexus specifies SAE 0W-20 full synthetic motor oil. This low-viscosity oil is important for a turbocharged engine because it flows quickly to the turbocharger and bearings during cold starts, when most engine wear occurs. When changing the oil along with a new filter, the TX 350 holds approximately 5.6 quarts. Because synthetic oil is typically sold in single quarts and five-quart jugs, having six quarts on hand ensures a complete fill with a small amount left for top-offs.
If 0W-20 is ever unavailable, U.S. Lexus documentation lists SAE 5W-20 as the acceptable temporary alternative — not a heavier grade. Any substitute should be replaced with the correct 0W-20 at your next service. Always confirm the grade against your owner’s manual.
TX 500h F SPORT Performance Oil Requirements
The TX 500h F SPORT Performance pairs the same 2.4-liter turbocharged engine with a hybrid system for 366 net combined horsepower, and it comes exclusively with adaptive variable suspension and Dynamic Rear Steering. Despite the added hybrid hardware, the internal combustion engine still uses SAE 0W-20 full synthetic oil, and the capacity remains approximately 5.6 quarts with a filter change. The 0W-20 grade is well suited to a hybrid, where the engine cycles on and off frequently and benefits from oil that reaches operating bearings quickly even before the engine is fully warm.
Because a hybrid’s engine may run only intermittently on short trips, moisture can accumulate in the oil over time. Following the recommended interval — and using the complimentary intermediate inspection to check fluid levels — helps keep the oil in good condition.
TX 550h+ Plug-in Hybrid Oil Requirements (3.5L V6)
The TX 550h+ is the top of the TX lineup, using a 3.5-liter V6 (engine code 2GR-FXS) paired with a plug-in hybrid system and offering a manufacturer-estimated 33 miles of electric-only range. Because of the larger V6, its oil capacity differs from the four-cylinder models. The 550h+ also uses 0W-20 synthetic oil; for the exact capacity, refer to your owner’s manual or have our service team confirm it for your specific vehicle, as the V6’s requirement differs from the 2.4-liter engines.
For 550h+ owners who use the electric range for most short trips, the engine may stay off for the majority of daily driving. That makes the 12-month time limit on oil changes as important as the mileage limit — even under low mileage, oil additives degrade over time and the oil should be changed annually.
Lexus Genuine Oil Filters for the TX
Using the correct oil is only half of the equation; filtration matters just as much. The TX’s engines use a cartridge-style oil filter with bypass-valve specifications matched to the engine’s oil pump, so the engine maintains proper oil flow even under load. Genuine Lexus filters are engineered to those specifications. Our parts team can confirm the correct filter for your VIN and engine.
Lexus TX Service Intervals
Lexus centers TX maintenance on 10,000-mile or 12-month intervals when using full synthetic oil, whichever comes first. Under severe conditions — frequent heavy towing, extensive idling, or driving on unpaved roads — a shorter 5,000-mile interval is advisable. (The TX line is rated to tow up to 5,000 pounds when properly equipped.)
At the 30,000-mile service, in addition to the oil and filter change and tire rotation, Lexus calls for replacing the engine air filter and cabin air filter and replacing the brake fluid, along with inspections of the brakes, exhaust system, suspension ball joints, drive shaft boots, and steering components.
Every new Lexus also includes complimentary maintenance covering the first two scheduled services — at 6 months/5,000 miles and 12 months/10,000 miles — through LexusCare.

| Coverage | Duration |

Quick Answers Before You Visit
What oil type and capacity does the 2024–2026 Lexus TX 350 use?
The TX 350 uses SAE 0W-20 full synthetic motor oil, with an approximate capacity of 5.6 quarts when the filter is replaced. Keeping six quarts on hand allows for a full fill plus a small amount for top-offs.
How often should I change the oil in a Lexus TX?
Lexus recommends every 10,000 miles or 12 months, whichever comes first, when using full synthetic 0W-20. Under severe conditions — heavy towing, extensive idling, or unpaved roads — consider shortening that to every 5,000 miles.
Can I use 5W-30 if 0W-20 isn’t available?
For the U.S.-spec TX, the listed temporary alternative is SAE 5W-20, not 5W-30. Use it only until your next service, then return to 0W-20. Always confirm against your owner’s manual.
Does the Lexus TX need a special oil filter?
The TX uses a Lexus genuine cartridge-style oil filter engineered for the 2.4L turbo or 3.5L V6, with a bypass valve calibrated to the engine’s oil flow. Our parts team can confirm the right filter for your VIN.
Is the oil capacity different for the TX 500h hybrid?
No — the TX 500h uses the same 2.4-liter turbocharged engine as the TX 350, so the oil type (0W-20) and capacity (approximately 5.6 quarts with filter) are the same. The 550h+ V6 differs; check your owner’s manual.
