Meaning, 1st oil change under my ownership. Current oil has 8k miles on it.

I went with Castrol Syntec European Formula (AKA German Castrol) 0w-30, which is BMW LL-01 approved and is a rather heavy 30-weight oil. I am taking it to 1 of the best reputed BMW indie shop which let me bring my own oil in

I hope to run the German Castrol for about 8k miles.
My next experiment oil might be the Pennzoil Ultra 5W-40 Euro, but if the GC does well, I might just repeat it.
