Lexus ES: Fuel information

You must only use unleaded gasoline.

Select unleaded gasoline with an octane rating of 87 (Research Octane Number 91) or higher required for optimum engine performance and fuel economy. If the octane rating is less than 87, damage to the engine may occur and may void the vehicle warranty.

At minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A.

■Gasoline quality In very few cases, driveability problems may be caused by the brand of gasoline you are using. If driveability problems persist, try changing the brand of gasoline. If this does not correct the problem, consult your Lexus dealer.

■Gasoline quality standards

■Recommendation of the use of gasoline containing detergent additives

■Recommendation of the use of low emissions gasoline Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated gasolines, are available in some cities.

These fuels are typically acceptable for use, providing they meet other fuel requirements.

Lexus recommends these fuels, since the formulations allow for reduced vehicle emissions.

■Non-recommendation of the use of blended gasoline

Lexus ES. Specifications

■Non-recommendation of the use of gasoline containing MMT Some gasoline contains an octane enhancing additive called MMT (Methylcyclopentadienyl Manganese Tricarbonyl).

Lexus does not recommend the use of gasoline that contains MMT. If fuel containing MMT is used, your emission control system may be adversely affected.

The malfunction indicator lamp on the instrument cluster may come on. If this happens, contact your Lexus dealer for service.

■If your engine knocks

NOTICE

■Notice on fuel quality

■Fuel-related poor driveability If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is encountered after using a different type of fuel, discontinue the use of that type of fuel.

■When refueling with gasohol Take care not to spill gasohol. It can damage your vehicle's paint.
