I have a 1998 Honda Accord ex 4 cylinder engine. If there is half a quart over the full mark, could it hurt my engine?
Assuming that you mean oil, probably not. But I am somewhat OCD on levels, so personally I would carefully drain a half quart out. If this was a result of an oil and filter change, the filter will take up some of that oil when you first start the engine. But it will not hurt anything if it’s .5 qt too full.
