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
■
Use only gasoline containing a maximum of
●
10% ethanol.
DO NOT use any flex-fuel or gasoline that
could contain more than 10% ethanol,
including from any pump labeled E15, E30,
E50, E85 (which are only some examples
of fuel containing more than 10% ethanol).
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.
The malfunction indicator lamp on the instrument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
If your engine knocks
■
Consult your Lexus dealer.
●
You may occasionally notice light knocking for a short time while accelerating or
●
driving uphill. This is normal and there is no need for concern.
