There is no advantage in street cars to use synthetic.

I have no idea where you got this information, but it's 100% wrong.
- There is no such idea as "designed for regular oil". What is designed into the engine is the grade of oil, assuming stock bearing clearances.
- There is absolutely an advantage to running synthetic. If the car is tracked or autocrossed, the oil will last substantially longer with a good quality synthetic. It's not a voodoo science. A higher quality oil can also reduce the oil temperature (friction makes heat).
A good quality synthetic will allow extended oil drain intervals as well. I have been forming a regimen based on my Blackstone Oil Analysis, something that every serious owner should do.
