Previosly u had mobil 1 synt.
First, did you ask for bottle oil, or did they get the oil from their drums in the back part of the shop??? I know at my shop, I use the 5qt Valvoline Synthetic jug to get my oil out of the back shop, whether it be conventional or synthetic... so maybe your mechanic reuses his oil jugs like I do.... Second, no the Mobil 1 5000 is not either a synthetic or synthetic blend, it is only conventional oil. If your that concerned, I would def go back and ask them where they got your oil from, if you did not ask for bottle oil, and why your mechanic poured in the Mobil 1 5000 mile oil....
