Engine oil Mobil or IDEMITSU
The 508 spec gets you better mpg and less dirty emissions. Gotta look at the bottle carefully. Mobil ESPX2 0w20 has that spec.
262k miles here on an M54B30 with 10k changes, Mobil 1, it's running great.
It should be fine. I use Mobil 1 and it's worked great.
I use Mobil one in Canada when it goes on sale synthetic 0W20 10 k intervals 13 yr old corolla 1.8 and 15 yr old tundra 5.7 350 k and 320 km ; no oil consumption work great
I buy 5 OE Toyota filters at a time from Amazon ( approximately $6 ea ) Purchase Ow-20 Idemitsu oil from NAPA ( ships free to my home ) in the cost saving 6gal box ( 24 qts ) for about $125 with their online coupon. Use this in both my Avalon and my Tundra- both run like a dream.
You must use Mobil 1 0W40!
Go for 5W40 rating. They work the best for all BMW diesel engines. I’d recommend the Mobil 1
Both are good, the high mileage and the restore and protect. I personally run Mobil 1 high mileage full synthetic with a wix filter and it has been great for me.
Expensive. I’d stick to Mobil 1 or Kirkland
Mobil 1 for me is like water in this car. I ran it for the longest time till I was tuned but switched over
