Oil treatments is a total waste of money so don't mix anything with the synthetic oil.
Nothing happens, they just mix. You can buy "blended" motor oil.
its the same process as changing synthetic oil, except you use regular oil.
Synthetic oil or a blend of Synthetic and regular oil is much better for your vehicle than regular oil alone. Synthetic oil is MUCH more expenshive. If you change your regular oil every 3 months or 3,000 miles I will be fine.
Yes, you can. It is even sold as a Synthetic Blend.
Yes you can.
Yes.
Yes but once you do there is no turning back and no mixing regular motor oil ever again with the synthetic oil....only straight synthetic....or use semi synthetic....now that can be mixed with regular motor oil in a pinch.

Regular oil is recommended by Jeep. Edit: Correct, Jeep does not make a recomendation to use synthetic oil. However synthetic oil will not hurt the engine at all. The recommended weight is 5w30.
