OMG when I went to change the oil in my car it was still clear after 5,000 miles using the pink K&N cartridge filter. It was the weirdest thing I have ever seen Now I use them every other oil change. I will NEVER use another brand filter again. Totally freaked me out.

I was told that the oil was changed when I bought this car used . But the oil was a little brown so I knew that it was synthetic. So I just changed the filter to a K&N filter and the oil changed back to clear, like new. I'll never use any other product, in any of my cars.
