Does the GX 460 require premium gas?
The Lexus GX 460 SUV does not require premium gasoline. It can run on regular unleaded fuel, which is the recommended fuel type for this vehicle. However, Lexus does suggest using premium fuel for optimal performance and fuel efficiency.
Fuel Requirements for the Lexus GX 460
The Lexus GX 460 is powered by a 4.6-liter V8 engine. According to the owner's manual and information from Lexus, the recommended fuel type for this vehicle is regular unleaded gasoline with a minimum octane rating of 87.
While regular fuel is acceptable, Lexus recommends using premium gasoline (minimum 91 octane) for best performance, fuel economy, and to help prevent engine knocking or pinging.
Benefits of Using Premium Fuel
- Improved engine performance and responsiveness
- Better fuel efficiency and slightly higher gas mileage
- Reduced risk of engine knocking or pinging, which can cause long-term damage
- Cleaner engine combustion for a smoother ride
The higher octane rating of premium fuel helps prevent premature detonation, which can occur in high-performance engines like the one in the Lexus GX 460. While using regular fuel won't damage the engine, premium fuel is recommended for optimal performance and longevity.
Conclusion
In summary, the Lexus GX 460 can run on regular 87 octane gasoline, but Lexus recommends using premium 91 octane or higher fuel for the best performance, fuel economy, and engine protection. The choice is up to the owner, but premium fuel is the suggested fuel type for this luxury SUV.
Does putting regular gas instead of premium hurt a Lexus GX 460 hurt it long term?
It will be fine. When it gets to a half tank, put Premium in it. One tank of a lower octane won't hurt anything.

What year to avoid Lexus GX 460?
The main Lexus GX 460 years to avoid are 2010–2013 due to potential issues like engine oil leaks (valley plate leak), as well as the 2010 model specifically, which had a temporary sales suspension after a rollover risk was identified during sharp turns. Later models, especially 2016 and 2017, may be more prone to oil leaks as well, though not as critically as the earlier years.
Years to be cautious about
- 2010–2013: These early models are more frequently cited for potential problems, such as the valley plate coolant leak, which can be expensive to repair.
- 2016 and 2017: These years have been noted by some owners as having a higher likelihood of oil leaks.
Model years generally considered more reliable
- 2014 and later: These models reportedly have a different, less leak-prone head gasket.
- 2021 and 2022: These years are specifically highlighted as being very reliable.
Other potential issues to consider with any model year
- Secondary Air Injection System: Problems with this system can be costly to repair.
- Suspension: Models with the optional AHC (Adjustable Height Control) or KDSS (Kinetic Dynamic Suspension System) can experience issues, though Lexus has issued a TSB (Technical Service Bulletin) to address a leaning issue in some earlier KDSS vehicles.
- Rust: In areas where roads are salted, rust can be a concern, especially on models driven in the North.
- Maintenance: Regular and consistent fluid changes, especially transmission fluid, are crucial to the longevity of the vehicle.
