When I pull my vertical positioned filter on my truck I get 1/4 quart of oil plus what's in the filter .The old one was a 20k rating as is the new one. I do not go over 10k and most often 8k. While I wouldn't use the Ultra for multiple OCI's that I normally run; I ask why such an emphatic statement? If I were running 5k OCI on either of the vehicles in my Sig, I would go 2 OCI's and not have a worry. To me, all depends upon the situation.
What is the point of not changing a filter anyway ? Vehicles are expensive , filters are not .
