LX570_OM_OM60L96U_(U) Fuel information ■
Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only
accommodates the special nozzle on unleaded fuel pumps. ■
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.■
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.Your vehicle must use only unleaded gasoline.
Premium unleaded gasoline with an octane rating of 91 (Research Octane
Number 96) or higher required for optimum engine performance. If 91
octane cannot be obtained, you may use unleaded gasoline with an octane
rating as low as 87 (Research Octane Number 91). Use of unleaded gaso-
line with an octane rating lower than 91 may result in engine knocking. Per-
sistent knocking can lead to engine damage and should be corrected by
refueling with higher oc tane unleaded gasoline.
At minimum, the gasoline you use shou ld meet the specifications of ASTM
D4814 in the U.S.A. .
