Would it be bad to go from using mobil 1 for like 3000 miles and then switching over to valvoline max life synthetic blend? or even conventional?

I've been told it would be really bad because of the type of oil Mobil 1 synthetic is, but really, what would it hurt, if anything? please help me out here.

The only reason I ask is because I remember seeing the stick on the window for the oil change was that it said valvoline max life on it.

It hurts nothing at all. You can even mix synth with conventional and it won't hurt a thing.
