15. Do I have to make adjustments to the engine for E10 petrol?If your car has a three-way catalytic converter and the car is E10 compatible, no adjustments are required. In these vehicles the fuel-air mixture is automatically adjusted by the Lambda sensor.
If the vehicle does not have a three-way catalytic converter but it is compatible with E10 petrol, it may be necessary in some instances to adjust the fuel injection for a richer mixture. This adjustment can only be performed using an appropriate measuring device.
