Oil.... synthetic to conventional?

[LoJac963]

I've never had a leak so I rarely check my oil levels but have never had an issue with burning oil. I've always ran Mobil 1 in all my vehicles including the 2.

Typically it is not a problem to switch back to conventional or the other way around. Some will say to mix each oil (same weight) while some sources will say to just do a complete swap. Depends where you read the info.
