From experience I have always used mobile 1 full synthetic in my trucks but like I was a rookie in sports cars I ask in the forum ChicagoZ.com. They recommended full synthetic 5-w30 performance AMS oil good for our vq engines with k&n oil filter. Now that's just what everyone recommended and I do it myself since the first oil change is been working fine for me so I recommended, now I have 8000 miles on the car and about to change it again I do it every 3000 miles.
