Research the particular oil you want to run. Not all oils by any manufacturer are ideal for your car.
When I was running Porsche track cars I ran Amsoil. Too many reports of guys running M1 and losing rod bearing #2 on 944's and 928's.
Now I run the M1 0w-40 euro, which is BMW approved and tests well compared to other oils. It is at wal mart so it is priced right.
I agree, they will find an out. Besides, how many engines actually fail do to oil problems anymore? Almost none.
