■
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 minimum detergent additives to clean and/
or keep clean intake systems, per EPA’s lowest additives concentration program.
●
Lexus strongly recommends the use of Top Tier Detergent Gasoline. For more
information on Top Tier Detergent Gasoline and a list of marketers, please go to the
official website www.toptiergas.com.
■
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.
●
Lexus does not recommend the use of gasoline containing methanol.
■
Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcyclo-
pentadienyl 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.

pens, contact your Lexus dealer for service.
●
Use only gasoline containing up to 15% eth-
anol.
DO NOT use any flex-fuel or gasoline that
could contain more than 15% ethanol,
including from any pump labeled E30, E50,
E85 (which are only some examples of fuel
containing more than 15% ethanol).

taining more than 15% ethanol.
