You may be right but I don't quite understand the comment. If there is zero oil consumption with literally any other brand of oil, what exactly does he have for comparison to the oil consumption seen with PP/PUP? This is an honest question and maybe I missed something in your statement.Definitely he is speaking comparatively. That's a very common complaint people have/have had with PP or PUP.
I simply want to know *how much* oil consumption he is seeing when using PP/PUP, this is commonly stated in quarts/1000 miles (or liters/1000 km) and no comparison is needed.
