@OVERKILLMobil using 15% POE in the aforementioned vintage 5W-20.
By the way, there's an interesting piece of history to explore. Before the famous 5W-20 (1975, M1 debut) oil made its debut, the company actually released another oil back in 1973. What's unusual is that this oil was initially targeted specifically for the European market. It appears that Mobiloil decided to test it overseas before the main (US) market launch. It had an SAE viscosity rating of 10W-50.
This marked the introduction of PAO oils (the first PAO oil) to regular consumers through commercial channels.
And here's the cool part: this oil wasn't just a rare marketing product. It was indeed sold and promoted, even with merch/souvenirs, across Western Europe. Its presence was particularly noticeable in Germany, where it gained significant attention. One can't forget the iconic Gemini 1-liter canister, which became known in Germany in the 1970s and played a role in establishing Mobil's reputation
Incidentally, the viscosity classification according to SAE J300 was not mentioned on the can; they simply proclaimed it as "the finest oil."
