So your point is that an oil that meets A3 is equivalent to BMW LL01 and A1 is close to A3, so an oil that meets A1 should be fine in the OP's BMW for a reasonable OCI, such as 5000 miles?
I will concede that an oil that meets A1 should be ok in this car for 5000 to 6000 miles. But, the only oils available that meet A1 are all synthetics.
I do not believe that most conventional north american SM dino oils meet A1. If they did, then why wouldn't at least one major manufacturer make this claim?
Maybe a more civil question would be:
If North American dino oil is the only thing available, what would you run in a 2003 BMW?
If I had to run dino oil in my 2000 BMW, I would use Rotella T 15W40 or Castrol GTX 20W50 and it would probably be fine for at least 5000 miles since I don't drive this car in the winter.
There is no SM dino oil that can match a BMW approved LL01 oil in extreme high temperature and extreme low temperature conditions.
I would much rather have someone run LL01 oil to intervals per BMW's oil life monitor than have someone run 5W20 dino for 6,000 miles, as was suggested in an earlier post and I have provided some evidence to show that BMW approved oil works over long intervals.
BMW LL01 is what is recommended and it works. Plus, if you run it to 15,000 miles it is just as cost effective as any dino run to 6,000 miles.
In addition, I do not believe that any oil that meets A3 can meet BMW LL01.
