Bypass filters also cost more than full flow filters. The factory installed bypass filters are pretty much junk.Yeah, I know ... but as already said, a bypass filter should be used in conjunction with a good full-flow filter. If not, then the debris that could cause wear or damage is still going round-and-round through the oiling system until the bypass filter happens to finally catch it.
If just running a bypass filter only like done 75 years ago was so great of a system, then every car made right now would just have a bypass filter on it and no full-flow filter used in conjunction with the bypass filter. That's not happening these days - it's not done for a reason. It would cut down on the number of oil filters being manufactured and make filter change intervals way longer if only a bypass filter was used.
