Not really, people will purchase the filters, bypass kits and the oil. You draw them in with the cost savings over changing oil as normal.I still find it strange. A business model of buy our consumable product once and never buy it again. Tough to stay in business doing that.
I suggest that the result would be different between an oil leaker and an oil burner.Some have vehicles that get to a point where only the filter is changed periodically, and oil never changed but is only topped off as needed. Most of these are adding a quart every 500-1000 miles. Any UOA's of these?
This is the way it seemed to me, had one of those Celica’s 2000 1.8l burned a quart every 100 miles, I always poured in new oil of whatever I could find on sale at Walmart. That oil always looked so dirty and as black as could be. Adding a quart every 100 miles you would think the oil would look brand new.I suggest that the result would be different between an oil leaker and an oil burner.
For an oil leaker, the oil and everything it holds in suspension is being replaced periodically. If you have replaced all the oil over a typical oil change interval I can't see why you'd want to replace it. Though it would make sense to replace the oil filter at a typical oil change change interval.
For an oil burner, I'm not so sure. If the oil is getting past the rings, I would hypothesize that only the oil is getting past and being burned and what has been held in suspension is being left behind and would therefore accumulate. The same might be true for oil getting past valve guides. In either case (until there is an oil analysis that showed otherwise) I'd expect that the oil and filter would need changing at some interval, and I'd start with the typical change interval.
I don't know any of what I've said above is true but that's where I'd start the discussion.
Nowadays if I had a vehicle that was leaking or burning oil at that rate I'd do something about that instead anyway. I did have an oil burner in my younger days (Ford 289 V8 with 80,000 miles) and it seemed to burn less oil when the oil was fresh. So I changed it for that reason as well. With modern oils I doubt that would be true.
