Hello Everyone,
I recently purchased a 2015 M3 with 19k miles. Ive done a lot of research on this forum and I seen some post on this subject, but I don't think they really answered my questions on this particular subject.
I am one to always purchase the premium engine oil, transmission fluid, and rear diff oil.
From my previous two vehicles I've always used Redline for all three applications. Redline also seemed to be favored on the forums for my previous two vehicles.
To my surprise from what I've searched not too many people use redline on this forum. This is also perfectly fine as well. I'm open to hear whats best for my car and hear opinions.
I have about 1 year on my factory warranty and I would prefer to not void it. However I would also prefer to put premium oil, DCT fluid, and rear diff oil in my car without voiding the warranty. I also bought a 3rd party extended warranty and according to my BMW dealer if I ever have any major problems they wouldn't really be able to see too much.
Engine Oil:
I live in Arizona where its very hot during the summer. It looks like the majority of people say as long as the oil is LL-01 then your good to go. On redlines website the 5w-30 says its LL-01. Would this oil void my warranty?

DCT Fluid:
Is this DCT fluid from redline safe to put in my car? Will this void my warranty?

Rear Diff:
Is this rear diff oil safe to put in my car? Will this void my warranty?

I'm also open to other premium products and opinions of those products for this car. It's my first one and I love it. I also want what's best for it too.
Thank you
