Toyota Yaris: Fuel and Engine Exhaust Precautions / Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY
UNLEADED FUEL, which will reduce exhaust emissions and keep
spark plug fouling to a minimum.
To achieve maximum engine performance, use the specified fuel.

* 1: U.S. federal law requires that octane ratings be posted
on gas station
pumps.
Fuel with a rating lower than 87 octane (91 RON) could cause the
emission control system to lose effectiveness. It could also cause
engine knocking and serious engine damage.
Gasoline blended with oxygenates such as alcohol or ether compounds are
generally referred to as oxygenated fuels. The common
gasoline blend that can be used with your vehicle is ethanol blended
at no more than 10 %. Gasoline containing alcohol, such as ethanol or
methanol, may be marketed under the name “Gasohol”.
Vehicle damage and drivability problems resulting from the use of the
following may not be covered by the warranty.
- Gasohol containing more than 10 % ethanol.
- Gasoline or gasohol containing methanol.
- Leaded fuel or leaded gasohol.
NOTICE
This vehicle is equipped with an emission control system (the catalytic
converter is part of this system) that enables the vehicle to comply
