Unless you can provide proof of your claim of course, I'm not going to go out there and lose time researching it myself  |
Yeah well owners manual have info that is to benefit BMW in a lot of different ways and often is has nothing to do with what is best or what the engineers would decide to have in it. Oil choices are made for lot's of reasons (meeting fuel mileage standards, lowering cost of ownership numbers, etc) that have nothing to do with what is the best for performance. Lot's of things change when you start adding power so recommended service intervals should change as well. The LL (long life) spec is just that, it's test created to ensure the oil meets the test specs so that the oil can survive the BMW CBS oil change intervals. But yeah if you are stock feel free to follow it, and if you have an auto let me know how that ATF looks past 100,000 miles.
