Good evening,new to the forum and looking for some insight into my Mazda 3 2.2 diesel auto 2017 model. I had the car fully serviced in January,then had to replace the start/stop battery last month but I’ve noticed now that my oil level on the dipstick is at the ‘X’ mark! According to the handbook this means I need to change the oil but given it’s only been just over a month since being changed I’m a bit puzzled. Any ideas? Thanks.
