Castrol Edge Euro 0W-30 A3/B4 Advanced Full Synthetic Motor Oil, 1 Quart, Pack of 6

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.

Castro Euro formula works great in the BMW. My wife’s X1 has 170,000 miles and I have used this exclusively. I pulled the valve cover to change the gasket and the engine is clean as new!

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

great product at a decent price.

I have two BMW's, a 2015 328i (75,000 miles) and a 2018 740e PHEV (90,000 miles), both with the 2.0 liter turbo. Sticker under the hood for both recommends "0w30". When I took them to the BMW dealer, I would be given the latest BMW 0w20 formulation, and I would have to add oil between changes. Sometimes within 3-4000 miles with the 2015, and usually near time for the next change on the 2018. Using this Castrol and doing it myself with a quality Mann filter, both cars go the full interval (8000 mi for the 2015, 10000 miles for the 2018) without needing to add oil. The 2015 stays halfway between "add" and "full", and the 2018 stays snug against "full" for the entire interval. The cars seem to like it. Mostly interstate usage for both.
