Pennzoil joins the 20k mile club?

That is true. It is just like their Ferrari F1 team. I try to avoid any engine oil that are advertized in F1 or Nascar, because their marketing cost went to the price we pay. From now on I will only buy trully PAO oil for about the same price as regular group III oil. They are relatively unknown brands:

1. Addinol: https://addinol.de/en/service-en/expert-tip/fully-synthetic-oil/
2. Meguin: https://www.meguin.com/en/engine-oils.html?_lart=14178
3. Kroon PolyTech: https://www.kroon-oil.com/en/news/expansion-of-the-polytech-range/
4. Carlube R https://carlube.co.uk/products/carl...w30-a3-b4-fully-synthetic-r-tec-16-20l-single

Alternative to expensive Amsoil and Ravenol for about €35 per 5L, a half price. I am not sure if we can be sly as a or in choosing engine oil.

I gotta say, i know none of these brands, i guess because they don't have a major (if any) US presence. Are these pure PAO? I wonder what they use for seal swelling

Technically that would not be possible.

They only mentioned >80%. Kroon contains PAG and Ester for solubility reason in their webpage. Addinol and Meguin are German company and Kroon is Holand/Netherland. Addinol, Meguin, and Kroon are pretty common in Germany. It is also available from Autodoc, similar to Rockauto in the USA.
