Best Engine Oil for Toyota Tundra 3.4L Twin-Turbo V6 (389 HP)
The third-generation Toyota Tundra (2022+) replaced its legendary 5.7L V8 with the V35A-FTS — a 3.4L twin-turbo V6 producing 389 HP and 479 lb-ft. This is one of the most significant powertrain changes in American truck history, ending Toyota’s 15-year commitment to naturally aspirated V8 power. The V35A-FTS uses two turbochargers, D-4ST dual injection (direct + port), and is available with the i-FORCE MAX hybrid system adding an electric motor for 437 HP combined. At 7.7 quarts with filter, the Tundra’s oil capacity reflects its full-size truck duty cycle.
Quick Answer: Recommended Oil
For Toyota Tundra 3.4L Twin-Turbo V6 (389 HP):
- Recommended viscosity: SAE 0W-20
- Oil capacity: 7.7 quarts with filter
- Required norm: API SP / ILSAC GF-6
Note: You need two 5-quart jugs. Keep the remainder for top-ups.
The V35A-FTS: Twin-Turbo Truck Power
The V35A-FTS is a 3,444cc V6 with twin turbochargers positioned inside the valley between the cylinder banks — a “hot-V” configuration that minimises turbo lag and packaging volume. D-4ST dual injection combines 350-bar direct injection under load with port injection at light loads, keeping intake valves clean and preventing the carbon buildup that afflicts single-DI truck engines.
Twin turbos share the engine’s oil. Both turbochargers are fed from the same oil supply, meaning the 7.7-quart capacity must manage the thermal load from two turbo bearing housings simultaneously. Oil temperatures under towing can exceed 250°F (120°C). Quality synthetic 0W-20 with strong thermal stability is essential.
i-FORCE MAX hybrid (optional) adds a motor-generator between the engine and 10-speed automatic. The hybrid system increases start-stop frequency — each restart demands instant oil pressure at the twin turbo bearings. The oil specification is identical for hybrid and non-hybrid variants.

Oil Change Intervals
Toyota Official: 10,000 miles or 12 months.
Recommended: 5,000-7,500 miles for towing. The twin-turbo system generates more heat than the old NA V8 — shorter intervals protect the turbo bearings.
Conclusion
The Toyota Tundra 3.4L Twin-Turbo V6 requires API SP 0W-20, 7.7 quarts. A revolutionary replacement for the V8 — twin turbos and dual injection deliver more power with better efficiency. Shorten intervals for towing.
