What is this oil I have never seen before? Is there any difference between this and the Mobil 1 0w-40 I have been running. Was going to buy the Mobil 1 0W-40 FS for its higher HTFS specs since this car sees 5-8 track days a year and its a VQ35HR so its super hard on oil (yes I do have a bit dual pass oil cooler so temps never go above 265F).
