Recommendation of the use of low emissions gasoline
Gasolines containing oxygenates such as et hers and ethanol, as well as reformulated
gasolines, are available in some cities. Thes e fuels are typically acceptable for use, pro-
viding they meet other fuel requirements.
Lexus recommends these fuels, since the form ulations allow for reduced vehicle emis-
sions. ■
Non-recommendation of the use of blended gasoline
●
If you use gasohol in your vehicle, be sure that it has an octane ra ting 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
(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 ad versely affected.
The malfunction indicator lamp on the instru ment cluster may come on. If this happens,
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 driv-
ing uphill. This is normal and there is no need for concern.●
Use only gasoline containing up to 15% etha-
nol.
DO NOT use any flex-fuel or gasoline that
could contain more than 15% ethanol, includ-
ing from any pump labeled E30, E50, E85
(which are only some examples of fuel con-
taining more than 15% ethanol). DO NOT use gasoline
containing more than
15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)

RX350/RX350L_U NOTICE ■
Notice on fuel quality ●
Do not use improper fuels. If improper fuels are used, the engine will be damaged. ●
Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic converters
causing the emission control system to malfunction. ●
Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performance problems. ●
Using unleaded gasoline with an octane numb er or rating lower than the level previ-
ously stated will cause pe rsistent heavy knocking.
At worst, this will lead to engine damage. ■
Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is encoun-
tered 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.
