Recommendation of the use of gasoline containing detergent additives

●

Lexus recommends the use of gasoline that contains detergent additives to avoid

the build-up of engine deposits.

●

All gasoline sold in the U.S.A. contains detergent additives to clean and/or keep

clean intake systems.

■

Recommendation of the use of cleaner burning gasoline

Cleaner burning gasoline, including reformulated gasoline that contains oxygenates

such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many areas.

Lexus recommends the use of cleaner burning gasoline and appropriately blended

reformulated gasoline. These types of gasoline provide excellent vehicle perfor-

mance, reduce vehicle emissions and improve air quality.

■

Non-recommendation of the use of blended gasoline

If you use gasohol in your vehicle, be sure that it has an octane rating no lower than

87.

pens, contact your Lexus dealer for service.
