This is the only oil I use in my 2011 BMW 128i. It’s one of the oils specified for BMW’s. I can’t speak to the specifics of this product only that I buy it here because Amazon has the lowest price. I know it’s high quality oil for high performance European engines.

This is the real deal- Germany produced, Euro blend, Class IV Synthetic. This is the oil that BMW recommends and uses in its new autos (which have an oil change service interval of 15K Km/10K Miles). What does that mean? This is a real, full synthetic, made with PAO/Esters. Most of the oil sold on the shelf and branded as "synthetic" are really just blends of high quality regular oil with a synthetic additive, but are not true synthetic, including those branded as Castrol Syntec. (all considered Class III oils) The only other true, full synthetics that I know of are Amsoil, Royal Purple, Mobil1, and Redline, which are a bit more expensive. The bobistheoilguy website, which bases its oil reviews on actual research and blind testing have found this to be a pure synthetic through chemical analysis. A lot of good information is on that website if you'd like to look into it further. Some of the benefits of running a true synthetic are extended intervals between oil changes (oil change every 8-12K miles) and much more suitable to harsher driving conditions, such as big temperature changes, cold start, high rpm, stop and go, short trips. There are supposedly slight MPG improvements, but I haven't noticed much because I have been enjoying how smooth my car operates on this, with liberal throttle application. This is a very well respected oil among auto enthusiasts, your car will thank you. I am using this in my 2008 Volvo C30 T5
