It says it is equivalent to the Shell and is $10 cheaper than BMW oil. Also how many quarts would be needed for two drain and refills?

I've not done a fluid change myself - many others here have and can give better advice - but I understand it's about 4-5 litres per change.
If you have ZF 6HP26 transmission, you'll need to use ZF Lifeguard 6 fluid. There are alternatives but most folk recommend the ZF fluid.
