I know Mobil makes conventional oils, but I believe "Mobil1" is strictly synthetic. The conventional oils they produce are under the name "Mobile 7500" or something of that nature.
Either way, I don't see the harm in having conventional in there for a little while. It's not nearly the crisis situation as some might have you think.
