I have never posted a question in this part of BITOG, but I ran across some information that I wanted to check out. I read about "European Castrol" fully synthetic engine oil. This oil is supposedly recommended by BMW for use in their cars (BMWs and Minis). It is not the same as the Castrol Syntec that you can buy at Wal-Mart. It is made by "Castrol Of Europe" and is a 100% synthetic that meets ACEA: A3/B3 and API: SL/CF Service. It is about $4.00 a quart and is available in the U.S., only from BMW/Mini dealers. Is the oil described above made by "Castrol of Europe", what is referred to as "German Castrol"? If this oil above, is better than Castrol Syntec you buy off the shelf, does this mean that it contains PAO's like Mobil 1? Any ideas or opinions on the information I came across? Thanks in advance!
