When I got home from work today, my buddy was talking to me about Royal Purple. A sales respresentative from Royal Purple was scheduled to show a demonstration of the top 5 leading(mobil 1, lucas oil, etc...) motor oil in the USA and compare all of them against Royal Purple. Basically, Royal Purple is best leading oil to use in any car and will not hurt the engine. It's a long process to type and im lazy to type it all out but, basically watch this video on YouTube and you will understand what my friend saw at work.
