What octane rating does a Toyota Corolla 2003 take? 87 or 92?
- thebax2006Lv 71 month agoBest Answer
I'd say 87 octane. If you are not going to check the owners manual or call the dealer try a tank of 87 octane gasoline. After the motor is at operating temperature find a steep hill and accelerate up it with the gas pedal to the floor. If the motor doesn't ping 87 octane is good. If the motor pings use higher octane gas.Source(s): Mitsubishi Master Tech

87b octane. Using a higher octane is a complete waste of money and will provide no benefit whatsoever.

The manual says 87. The car says 87. 92 will not hurt anything, as long as it isn't flex fuel

Check your book(owner's manual), and/or check your gas flap (the door you open to fill the tank).

87 octane, E15 not recommended.

Is the octane rating based on RON ( Research Octane Number ) or MON ( Motor Octane Number )? There is even a 3rd possibility, PON ( Pump Octane Number ) which is the average between RON and MON. In other words, it depends on where in the world you are as the octane number stated at your local refueling station is not universal.
