When you say broke down, did it stop running completely or did you just pull over because of the smoke? If you had just had the oil change, they might have forgot to put an oil filter back on, accidentally double gasket the filter, or forgot the drain plug. Also they may of just spilt some oil and the exhaust manifolds would produce smoke because of this.
I would do is get the computer (OB2) scanned. This will make it easier to help in the diagnosis. Most auto part stores will do this for free. When you get the codes, write them down and let me know what they are. There are many problems that could create this symptom and without speculating for hours let's try this out first and I'll be happy to help you out in finding the problem.
Thanks, look forward to your reply
