问：我的汽车仅在2012年5月的CORSA服务，为什么油灯B会出现。

Hi there:

If you had to add 2 liters of oil to your Corsa, that’s most likely an indication that you have a low oil pressure issue, that not enough oil was added during the oil change or an oil leak. Any of these three issues could cause the oil light to illuminate. You might want to have a professional mechanic inspect your vehicle bycompleting a check engine light inspection.
