Hey guys, i was just wondering if ive been putting synthetic in my car but want to go regular, is that bad? would things get messed up?

ive searched online and asked some ppl but im getting mixed answers. Some say theres no proven fact it was cause things to damage. Its a inline 4 cyclinder 2.4l pure stock, so i see no reason to go pure synthetic.

Thanks for any input.
