Yes, you are right, but BMW never approved semi-synthetic or mineral oil for their engines the last 20 years. So I thought that this Valvoline product will be fine... and 5W-40 is the perfect viscosity for my local climate..

The car is BMW 520i Touring E39, engine is M52TUB20. My concerns are that this oil does not have any BMW Long-Life specification.
And maybe VW has more demands on oil, but here
I would rather continue with the old CASTROL MAGNATEC 5W-40, which had LL-98 but it is off production - nowhere to buy. I think that the new variant C3 is just not good for my case.
So I was thinking of the fallowing options:
1. Buy LL-98 from another oil maker, or perhaps LL-01.
2. Buy Valvoline MaxLife Synthetic 5W-40. Online "Valvoline oil chooser" advises me to use it, just wanted to hear some opinions here if it will be good for the engine
As for the engine: it is about 250k miles, does not burn oil yet(!). Oil was always at MAX level from change-to-change and I never ever topped up. It was always filled with Castrol - firstly Castrol TXT 5W-30 from BMW service. I bought it 6 years ago, and it is very good family car, enjoyable and we are quite happy with it.

Well good points on your opinion!
This system was revised 2 years ago, it was like brand new. But I will check it again, just it is not suspected to be wrong.
