CastrolEDGE 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.

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

Castrol Edge Euro 0W-30 A3/B4 full synthetic engine oil is the recommended oil for my Volkswagen Atlas equipped with the VR6 engine. I've noted initial start-ups are quieter which is greatly appreciated. At just under $9/qt. the price point was attractive.

Package is perfect in terms of affordability and function. I've been using this on my 2017 BMW 440i with the B58 engine for the past 3 years and had zero issues.

I am an auto detailer and take care of all my vehicles. I changed this oil after 9k miles. I think this is a better product than what my bmw dealer uses. It is to spec according to the owners manual, and my car drives much smoother and quieter. I have 60k miles on my 2018. Let’s see if I can get another 10k with this oil. I live in Ohio where the climate changes daily.

I have been using these with a 98 Integra Type R for the past year and a half. The car is mainly daily driven with no track time. The ITR is known for burning oil especially if you do a lot of spirited driving and engage the higher rpm. The ITR burns the least amount of oil with the German Castrol, compared to Amsoil, Mobile 1 synth, and Castrol Edge dino (oils I have used in the past). I have done 2 oil changes with the German Castrol at about 6000 miles for each (roughly 8-9 months period). Oil analysis were done with Blackstone Lab for each of the oil change to verify residue/contents, which confirms that the oil is chemically still very good if you want to push it another 2-3k miles. Oil viscosity is also the highest compared to other oils I have used prior, with Mobil 1 being the thinnest. Overall, it's a bit more expensive than other brands, but it works pretty well for my application and I have been happy with it.

I use this oil for my 2019 Audi A4 Quattro. I’m very pleased.

I use this in my 2015 BMW X5M. It is good oil and well suited for my car. I just wish it didn't cost so much? Oil is manufactured in Belgium, maybe that is why it is costly?
