Bet you can't wait for the long days of summer!
I went 16k miles on my last round of Amsoil. When I changed it it was still pretty clean and the filter was still good, but I already bought the replacement oil and filter. Haha. Amsoil's extended interval costs around $90 shipped for 6 quarts and a extended filter. And can last 20k miles, I guess. Rated for up to 25k.
And btw... Your car is awesome
