I like the Redline 5w40 for my Super Sport. Keeps the turbos lubed and even at 268mph on my local highways it purrs like a.kitten. A very large, angry kitten trying to claw your eyes out, but a kitten nonetheless. It sure is a pain having to fly in the.French mechanics every 3k miles and buy new tires every 5k though. The croissant bill alone is frightening!
However, once you put in that special key and launch it at 4krpm and feel the tires grip immediately as it catapaults you into hyperdrive, you know that its worth it.
Oh, ahem, sorry... Dreaming out loud again. Darn!
