Burning your Oil (instead of changing)

[Crazy Dazz]

One of the sites I worked on, they converted the trucks to burn their oil.
ie such that the oil was continuously being replenished and never changed.

Obviously that works best in a diesel.

Could you implement that on a petrol engined car?
Would the engine management cope/ adapt?

How would you implement it?
Where would you take the oil feed from, bottom of sump or bottom of oil-filter?
How would it be injected? Presumably it would clog existing petrol injectors. Could it be rigged to spray into in the manifold at WOT?

And what would the effect be?
The advantage on the fleet was burning the oil inplace of diesel, but mostly to avoid the cost of changing and disposing of the oil.

Not sure, but I imagine the filters were still changed, as they would still have caught all the dirt and particulates.
