Kind of a good question, as some do that with the bypass filters, so maybe with a really good filter like a fram ultra, and changing it and topping off the oil every 5000 miles or even less???? But then even so, probably not the bes idea if you want the engine to last 200k or more. But then it may depend on the type of driving you do also. I had an uncle that back in the early 60's had a 59 ford 6 cyl. stick, that he drove a 80+ mile trip to work and back every day. He never changed the oil, just the filter and kept the oil full. He would run them 100k and drop a new (rebuilt) engine in. And of course the oil those days wasn't nearly as good as today, and no synthetic.
