It´s a Company like Eurolub, Mitan, DBV, Rektol, Voltronic, Bizol, Kroon Oil, MPM, Eurol and so on... you name it.
To my best Knowledge, wich could be wrong, all these companys buy oil and additive packs, blend it, and sell it. This should work well.
Sometimes the approvals are real - look at the mercedes benz BEVO list - or they are just "Reccomendations" or "Equal to..".
It´s your decission. I use Eurolub for my winter beater since many years, because it is around here in many shops cheap since years. No complaints.
