If you search you will find that I was one of the first to recommend Mobil1 0w40 oil for our cars. I ran it in my 2008 through 2 engines and many track days. After putting my car in the wall at a local track I bought a 2006, completely stock except for a catch can. I decided to protect the motor with the best possible oil. My research indicated Redline so I bought it even though it was the most expensive oil on the market. My Blackstone reports had me concerned about high lead levels. I addressed this concern on Bob is the Oil Guy. And many there suggested that I should use the oil I was very familiar with ....... Mobil1 0w40. Please look at my report and you will see that my lead levels have dropped to normal with the Mobil 0w40. At least for this motor the results are indisputable..........Mobil1 0w40 is THE OIL to use. 
My Pick for Best Oil: Mobil1 0w40
