There is not much to say to the engine oil itself. Castrol stands for good quality and a lot of authorized workshops of VW, Audi & Co used engine oils Castrol. That alone speaks for itself.
In the various reviews on this engine oil we read so many things that I would like to go into below:
CONTENTS
Some critics claim that in the bottle are only 4 liters. That's nonsense. On the bottle itself although there is only a 4-liter mark, but anyone who is a bit closer inspection noted that the level is much higher than this mark. 5 liters is above and 5 liters are inside.
FORGERY
Apparently some have a fear that it is in this engine oil is a counterfeit and genuine motor oil from Castrol would be much more expensive. I personally have the engine oil purchased directly from Amazon and not from a third party. For this reason alone, I am assuming that it is original motor oil from Castrol. I suspect that Amazon, the engine oil in large quantities directly from CASTROL applies and this results in the affordable price. Apart from that, it can not afford to Amazon fake engine oil to sell. Imagine only once before the scandal if such would publicize. I can of course not guarantee, but from my point of view I think it is highly unlikely that it is a forgery.
EXPIRY DATE
Those who fear that it is old oil, I can calm down. In the pack is the filling date. In my case the oil at the time of delivery was just 1 month old. And be honest: Do you know always exactly how old the oil is that fills you your workshop at the service?
Acceptance WORKSHOPS
Apparently there are workshops, do not accept the Packed engine oil or require a certificate of authenticity. Whoever listens to whatever kind of his workshop, they should change quickly. In my view, such a procedure is absolutely frivolous and only aims to attract customers over the table. A certificate of authenticity brings exactly nothing, since it does not prove that the bottle is actually original oil. Is not the seal on the bottle proof enough?
CONCLUSION: A super brand product at an unbeatable price! Absolute buy recommendation on my part!
UPDATE 05:09 .: Today I have my car brought from the service. The engine oil has been brought without hesitation accepted by the Audi workshop. Bottom line, the saving for the last service is more than significantly failed!
