Hello, guys! How are you? Due to the fact that BMW Original Oil (the twin power turbo-5w30) comes at an astonishingly low price at car parts shops and online shops(like 7-12 bucks), I was wondering if somebody knows what is the difference between the oil you buy from a car parts shop and the one from the dealership(which is like 25 bucks and more). The difference is double and I can't stand thinking that the low priced one is either a fake product(though it has the same manufacturer, bottle etc) or the same one as from the dealership(and we are buying it at double the cost). Moreover, I want to say that many other great brands of oil like Motul, Liqui Moly and Ravenol come at a much higher price than the BMW original one per litre. Like 1l of original is 7-12 bucks and the other brands hover around 25-30$. Furthermore, I will attach a link in which you can see for yourself some data about many types of oil, the bmw original one coming on the last places at wear and resistance. Hope we will find some light in this "problem". Thank you in advance!

P.S.:the oil from the dealership I looked around the world and it has the same price 25$ or more, through BMW.
