Even an engine that consumes oil requires regular oil changes in order to dispose of everything collected by the oil.

That would depend on how much oil it's burning. A quart or two over the oil change period and I would agree with you. However, if it's burning 5 or 6 quarts over that period, you're replacing all the oil anyway, so no point in changing it.

If it is burning everything, I would still do a flush, but that's just me. And at the point the engine is no good, burning that much oil.

Whichever way you go on oil you need to change the filter every 5K or so.

About the suggestion to flush the engine, the owner should be careful with older engines. I flushed the V8 engine on my then-Ford and that loosened some gunk in the oil passages which subsequently clogged the passages leading to the valve gear. Result was that I had to have some rocker arms replaced, but fortunately the rocker arm shaft was salvageable.

the way I flush the engine is to top off the engine oil with the clean oil recommended by the manufacturer, start the car and let it run for 5 mins, drain it, replace the filter and then refill it with clean oil to the max line.
