Warnings symbols are on cars to let the driver know of any problems. Some warning lights for the VW Polo are the check engine light (words or engine), oil can (low oil), gas light (low gas), airbag light (airbag issues) and the wiper light (low fluid).
The warning light will not come on because you have a separate oil gauge on the Ford Focus. This is the gauge that you should watch and it will show you that you are low on oil; do not rely on the check engine light to alert you of it.
Low oil will trigger a different warning light, specifically the low oil light will come on.
No, the check engine light has nothing to do with the oil level in the vehicle. The check engine light will come on when there is a problem with the emission system. The red oil warning light will come on if your vehicle is low on oil.
The warning light can come on when it is time to change the oil. Your oil pressure and oil level can be at recommended levels when the oil needs to be changed.
