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

I just want to address the concern expressed about the lack of BMW LL-01 approval. In 2018 BMW changed the specification of their oil. They had a lot of timing chain failures on the N20 engine (4 cylinder turbo), it had poor design/quality control on the timing chain guides. However! This is the correct oil if your BMW is 2019 or older and NOT an ///M car or diesel. The newer specifications are not necessarily friendly for older cars with respect to changing the formulations to comply with resource conserving and emissions laws (low SAPS, or Sulphated Ash, Phosphorus and Sulphur) Those additives tend to be poison to catalytic converts and new low particulate diesel emissions systems. However, those same ingredients can be beneficial to lubrication. Same is true for mandated fuel mileage in the SP rated oils, good for mileage, not necessarily good for lubrication in older engines. Generally there is no problem at all to use the newest spec SP oils. Where I would be careful is with the LL-04 and ACEA C rated oils. Those are Low SAPS oils for diesel engines generally but also cover gas engines with a SN or SP rating. BUT these ARE GENERALLY ACCEPTED as not as good a choice lubrication-wise for gas applications, even though they meet the SN or SP spec. Evidently this is particularly true if you have mandated ethanol mixed in your gasoline and follow extended drain intervals (factory service computer). Trivia: Look carefully on the back of the bottle, and you'll likely find this 0W30/0W40 oil is made in Belgium. It will be the ONLY European oil at Walmart. It is excellent oil. I've used it in BMW's and other German cars for 30 years. Be aware that the Mercedes specification is generally more stringent than the BMW LL-01 specification EXCEPT for oxidation. BMW raised this requirement in an attempt to go for extended drain intervals (over 10,000 miles) So new rule of thumb: Mercedes 229.5 approvals in place of LL-01 generally will keep you using high quality oil for Euro cars. This is killer oil for US and Japanese cars too that don't require 20 weight oil. One more misconception I would like to blow up permanently as I'm soooo tired of hearing it. Many people, mechanics included, think that 0W is "too thin" for their application. Wrong sports fans. 0W30 stands for 0 weight AT A VERY LOW TEMPERATURE and 30 weight at room temperature (approximately) and higher. Its for cold starts and pour-ability in freezing temperatures ONLY. It has nothing to do with the oil after outside temperature rises above room temperature. FURTHERMORE, to get oil to perform at the wider range that 0W offers vs a 5 or 15W oil, listen closely now, you need a HIGHER QUALITY base stock oil to start with. So a 0W30 or 0W40 oil is generally going to have a better Viscosity Index (VI) than a 5W or 15W40. This is a good thing. VI measures the oils ability to stay in range, viscocity-wise, under a wide range of temperatures. Use this oil, it won't let you down.

Used Castrol Syntec (Edge) for 20 years in my car.

Giving this 1 star because the picture in the ad is wrong. This oil is likely great oil, however it is no longer BMW LL-01 approved. The bottles I received only had VW and Mercedes approval.
