What does Redline sell for in Ukraine?

First question that comes to mind is "why"?

 

[fantastic]

Viscosity held good at 14.2 after 9000 kilometers. I can't decipher if this shows an oxidation reading or not?

I don't see anbything wrong with that sample, ciould have gone a lot further.

Iron is low 5ppm for 9000 km works out to under 1 ppm/1k miles. remaining TBN = 7.
The acid number is elevated but it always is with ester containing oils, even when new.

Honestly, that oil would have done 15,000 km easy.

No lead in the list of wear materials, that's unusual

I ordered it from Amazon before war. And analysis was in 2021

TAN 4.21
TBN 7,37
In virgin oil (at least 5w30 2014 г.) TAN 2,82 TBN 10,44

So for me it was an experiment to refute two myths: 1) ester oils run out quickly 2) PEA cleaners kill oil
