BMW branded oem oil (made by Pennzoil/Shell) is quality stuff as well.
DCT fluid - why do you want to change this? It is not as simple of a process as a manual transmission fluid change. Also, your car only has 19k miles on it which is nothing. I would leave it alone if I were you. But if you absolutely insist on changing it then I would stick with OEM fluid.
Diff fluid - again, why do you want to change this at only 19k miles? I would wait until 50k miles. But again if you insist on it, I would stick with OEM fluid.

From my understanding Amsoil, Redline, and Royal Purple were the Premium oils, transmission fluid, and rear diff products to purchase. These products were always favored on the other forums I joined. That would be a Lexus ISF forum and a Volvo forum before that.
I've read a bunch of talks about the subject here on this forum and everyone seems to like BMW OEM products. Who makes BMW's engine oil? Transmission fluid? Rear diff oil? I've gotten mixed answers. Ive herd it was castrol and then they switched to Pennzoil. I called my BMW dealer and they tell me that BMW has made its own formulation for all three applications. So I'm also slightly confused on what to believe and whats actually inside of my vehicle.
With my previous two vehicles I ran Redline and to be honest it was great. I'd give it an 8/10. I've read a lot of mixed issues with Royal purple. I was leaning towards switching to Amsoil. From all the research I've done it seems to be the best out there. However is it the best for my M3?
Some other guy from another thread posted he runs all these. I was considering doing the same thing.

I remember seeing you Gatorfast answering most of the questions from the previous threads I read. I appreciate your input and help with my questions.
Thank you.
