I do love this oil, I realize its rather pricey but I do get it whole sale which makes it roughly 6.5 a quart. That's something I can handle when I would be changing mobil 1 or penz plat every 7k.
I was using a wix filter which half way prompted the change alomg with I was nervous of any metal that might have been floating around from the swap.
I went with the amsoil filter after the change along wity more amsoil signature and am thinking running it out to about 15k before I change again.
