Dirty Oil .....high useage ?

I would like to ask for facts/ opinions on this subject........Would very dirty ( Black ) oil tend to get past the rings and be used/ burned in a engine that has high mileage but does not use it normally ?.....Reason that I ask is a discussion about this came up with coworkers. One swore that he bought a DD that the PO sold because it was using oil, he said he changed the oil and filter three times in a row until he was able to go more than a few miles with out the oil turning black again and it quit using oil at the rate it had been and is still doing the same about 1 year later.I have worked on cars for over 50 years and never heard or seen any thing like this. Only thing that i could think of was the oil viscosity got very thin as it loaded up and was able to go past rings that normally would not allow that much oil past the rings.
So what do you think.....
Kenny

sounds like an engine that had a stuck ring or two.. and it cleared up.. from clean oil and use..
or just cleaned out the oil drain back holes in the heads.. so the valves where not swimming in oil anymore..

Maybe he used a non detergent oil and it got gunked up to the point of sealing everything.

If the coworker used a 'high mileage' motor oil or an additive that softened the valve stem seals and/or slowed leakage out of the engine that wasn't being burned in the first place, that might have bought him some reduction in motor oil use. It could even be something as simple as how the new owner drives compared to the seller's driving habits- hard driving will obviously tend to use more oil than driving it easy. The amount of miles driven matters, too.

In any event I usually chalk this type of 'evidence' up to wishful thinking and the placebo effect.

BTW, black oil is not necessarily an indication of how "dirty" it is. But I follow what you're saying.

Possibly, the old black oil was so thinned with gas that it was getting by the rings and the new thicker oil didnt. But that would have cleared up the burning oil almost right away

Thanks everyone for the replies....I personally thought the guy was BS ing me as I had installed new valve seals in this motor about a year or so before this guy bought the car , the PO never changed the oil after he got it back from me .the man has a history of not taking care of his cars. Any way I was trying to find some reasoning behind this....also the oil being gasoline polluted never crossed my mind and that makes perfect sense. Thanks guys

I´ve taken oil out of cars that has been black but also ran
out like water, totally used up.
Last one was an Alfa Romeo, last oil change "A little over three years ago".

MOTOR OIL MYTH VS. FACT

Want to know the inside scoop on some of today's most notorious oil myths within the automotive world? Well we've got you covered. Select a myth from the pull-down below, and we'll give you nothing but the facts.


Myth: Oil Color
You can tell the condition of oil by the look, smell or color of it. And if it turns dark or black quickly, it’s no good.

Fact:
Nothing could be further from the truth. If the oil is doing its job of cleaning the engine, then it should be dirty when it is drained. Quaker StateŽ motor oil will start looking dirty a short time after it is put to use. In the case of diesel engines, the oil may look dirty within a few hours of operation. These are signs that the motor oil is doing its job of keeping soot, dirt and other combustion contaminants in suspension to be carried to the filter or removed from the crankcase when the oil is changed. Quaker State motor oils have been formulated to hold these contaminants in suspension until they can be removed with an oil and filter change.
