Hi everyone, hope all is well. So my oil change indicator came on and I went to get an oil change. The usual place I go changed the employees and none of the old guys were there but I still went ahead with the change. They said the oil wasn’t dirty but just low. So they put a quart of oil in for me for free. But, shouldn’t they have checked to see if my oil filter was ok? Or do you not have to change the filter every-time there is an oil change? Now, I haven’t driven my car very much but idk. Will you tell me your thoughts? Thank you.
