Natural to Synthetic Oil, any complications? Options

[hurley97]

I've always used natural oil because thats what I assumed the previous owner used. I want to switch to synthetic but I've heard bad things could come from doing so after using natural for so many years.

I can't remember exactly what possible problems I was told could arise nor can I remember where I heard it but it had something to do with the deposits that form and casing leaks, etc.

Is this just a myth? I plan to just flush the system like I did when I switched weights, would that have any negative consequences?

i switched my 7afe from penzoil dino to mobil1 full synth at 114K miles with out any problems, and i'm now running mobil1 synth blend 'clean 7500' because it costs 1/2 the full synth. i had no leaks, drips, or seeps that werent there before or werent due to age (seepy valve cover, just a small amount of oily buildup that i wipe off from time to time)
