My CX-5 has recently had its first oil change from new as part of the annual Mazda service. I check my oil levels monthly and from factory it had always been at the max mark - historically I have always checked it cold in the garage and only recently learned that the manual recommends warming the engine first (not sure how much of difference this will make on the dipstick).
Anyway, after the service the next month I checked the dipstick to find out that it was quite overfilled - see image below.
Unfortunately I had driven around 1000 kms by this point and I'm worried about any long lasting damage that may have been caused. I took the car back to the Mazda garage and explained the situation and they drained the oil and refilled it. After I got home I have rechecked it and to my amazement it is still over the max mark as below.
Took it straight back to the garage and the head mechanic took a reading (engine wasn't cold this time as with the previous readings since I had driven to the garage) and although it was over the mark said that the reading was fine.
At this point I honestly don't know what to believe and am looking for a second opinion. Do I need to go back again and have some more oil drained?
