I felt a remarkable performance improvement and increased smoothness after my first oil change at 6K miles. I chalked it up to a software upgrade. I felt the same again at 12Kmiles. This time I had new tires and another SW upgrade. Well now I am at 19K miles and I cannot wait for the oil change scheduled in a couple of weeks. When I mentioned this marked improvement post oil changes to my SA, he noted that several 545 owners expressed the same thing. I dont think it has anything to do with SW. This engine needs new blood ever 6000 miles, no ifs and no buts. I don't care what the BMW recommended service interval is. This V8 needs it sooner.

It depends on what type of loaner car you had or what car you drove before you received your V8 back from the dealer. This a "feeling" thing is is relative.

It is an well known fact, that a BMW engine will give its best after some 30 - 40,000 miles.
A other psycological fact is, that one always feels the car better after maintance

Well my issues are not related to the tranny as I have a 6spd. Confirmed today that most probably my 13mpg driving style and route (can't be helped) breaks down the oil faster. My Mechanic is convinced that fresh oil will always make a big difference and that it is not SW related.
