As the title says "Maybe Pennzoil Ultra Platinum burning off more than most other brands is a good thing" because this might mean that it is actually getting into the slots that the piston rings are in so it can work in that area to keep it clean. Think about it. Pistons move at fast speeds during the up and down part of the stroke, and at low speeds at the bottom and top. For an oil to keep those groves cleaned out it has to first get into them. Once there it has to dissolve anything there, then to complete the cleaning job it has to leave while carrying away what ever it removed. I can see that with the speed of movement the leaving part can end up with that oil either going into the combustion chamber, or the crankcase. Probably some ends up going in one direction and some in the other.
Everyone who want an engine to last a long time, also wants that engine to not be a big oil burner when it is old. In order to achieve that those piston ring groves and rings themselves must be kept clean.
So, maybe PUP is a very good oil for keeping piston rings and the groves in the piston they rest in clean, and the price we have to pay for using an oil that does get into this area and do that work is topping up the crankcase more often because of the amount that leaves that area via going into the cylinder and getting burned.
This may be a good thing because:
1) The oil is doing a good job of keeping the piston groves and rings clean which means in the future those rings will still work well.
2) The oil that gets by is lubing the pistons and cylinders.
If this is what is going on, then the price we have to pay for using an oil that gets this job done is topping it off more often.

You pays your money and makes your choice.
Or just maybe your choice is to use another and not pays your money and use a different oil and end up with piston groves and rings that are not kept as clean.
--------------------------------------------------------
So, the question is: is this why PUP burns off more than others? And if so, is this something we should be wanting in an oil?

My low mileage 2016 Honda CR-V with the 2.4 four banger normally asperated engine did not require any oil to keep it at the full mark with the oil the dealer put in it before I bought it used with 19,877 miles on it, and ran that oil for a normal OCI. But PUP with a Fram Ultra filter on it now does require topping it off a little every once in a while. And PUP is supposed to keep an engine cleaner than most other oils, including especially the piston groves for the rings and the rings, so years later when there are high miles on that engine the rings seal well and it is not a major oil burner.
I see post that several have stopped using PUP because they had to add oil more often. All this and my own experience got me thinking, and I realized that just maybe PUP is getting into those piston groves and doing a good job. And as long as it is not fouling the spark-plugs, maybe adding some oil now and then is not that bad a price to pay for using an oil that is doing a better job than others. So for now I will keep using PUP until someone convinces me there is a better reason to not use it.
