What kind of gas does a Lexus LX 570 take?
The LX 570 runs on regular unleaded gasoline with a minimum octane rating of 87 (AKI); higher-octane fuels can be used, but premium is not required for typical driving. Gasoline with up to 10% ethanol (E10) is generally supported. This article explains the official fuel guidance and practical fueling tips for the LX 570.
Fuel requirements and octane recommendations
The LX 570, powered by a large V8, is designed to run on regular unleaded gasoline. The critical specification is octane: a minimum of 87 AKI (octane rating) is recommended. Using fuel below 87 can cause knocking or reduced performance, especially under load. While you can opt for higher-octane fuels (such as 89–93), most daily driving does not require them, though some drivers towing heavy loads or operating under strenuous conditions may perceive marginal benefits.
In addition, the LX 570 generally accepts gasoline with up to 10% ethanol (E10). Avoid higher-ethanol blends unless your regional manual explicitly allows them. Do not use diesel or other non-gasoline fuels in this vehicle.
Key fueling guidelines:
- Fuel type: Regular unleaded gasoline only (no diesel or alternative fuels).
- Octane rating: Minimum 87 AKI; higher-octane fuels (89–93) are permissible and may offer marginal benefits in certain scenarios.
- Ethanol content: Gasoline containing up to 10% ethanol (E10) is generally approved; avoid higher ethanol blends unless specified by Lexus for your region.
- Fuel additives: Follow Lexus recommendations and avoid unapproved additives that could affect engine performance.
Concluding note: For most LX 570 owners, filling with regular 87-octane gas is sufficient. If you frequently tow or drive in demanding conditions, you might experiment with higher-octane fuel, but do not expect dramatic gains in everyday driving.
Model-year and regional considerations
Fuel specifications are broadly consistent across LX 570 production, but regional markets may have slight variations. Always verify the exact requirements on the fuel door sticker or in the owner's manual for your year and country.
Why octane matters
Octane measures a fuel’s resistance to knocking. The LX 570’s engine is engineered to run on 87 AKI and up, with higher-octane fuels available if desired. In typical daily use, most drivers won’t notice a significant difference between 87 and higher octane, but driving conditions like towing or high-speed terrain may influence the decision.
Summary
The Lexus LX 570 is designed to use regular unleaded gasoline with a minimum octane of 87 (AKI), and it generally accepts gasoline with up to 10% ethanol (E10). Higher-octane fuels are optional and may offer minor benefits in specific situations. Always check your model-year manual or a dealer for any regional nuances, and avoid diesel or non-gasoline fuels.
