I actually ran QSUD with an Ultra for my first oci. I cut that one open at same time as this one. The filter run with QSUD was clean like what we mostly see here in this forum. This was my second oci on the car. My belief is that the Synpower did some serious cleaning but the Techron had to have been a part of what you see in these pics.
