Very interesting and informative. Was this a favor performed by a lab for you or was this something that you specifically asked for in testing?
I'm assuming there was a nominal fee????
I went over 400 miles today; a couple of friends came by for quick rides in the new coupe. I can't wait to get to 1200. :drive:
Their numbers are based on an average of whatever they get from customers. For the S54, that average was 4,570 miles as of November 1, 2005. I sort of wish they'd report the median and not just the average. One outlier completely skews average calculations.Ron Stygar said:http://www.blackstone-labs.com/
It's $20 plus your shipping for the basic analysis.
I send it priority mail with tracking so it's $20 plus $4.55.
I started doing this on my '01 S54 because of the blow up issue.
Some have got replaced engines based on the analysis.
So on the '06 S54 I decided to start from the begining.
I think that their numbers are based on 4500 miles so I've been changing my oil every 4500 after the 1200.
For my annual mileage it is 1.8 oil changes per year.

There are good and knowledgable people (and engine builders) with differing advantages/drawbacks who disagree on how to break in a motor.Goodwood said:Who can possibly do that? :wow: Not me. I can see gentle launches and short shifting, but NO full throttle for an entire 1200, fogettaboutit! :bs: Breaking in my E60 M5 was agonizing, and if it also said no full throttle, I didn't adhere at all to that recommendation. I did however, avoid any full throttle launches for the full 1200, and always short shifted at the recommended rpm. OH well, each to their own wrt breakin.
I do all of my own work in my garage when I can.Just a couple of questions....
- On your first oil change, was the sample taken by the dealer during the first service?
- I notice you listed 10w/60 on your first interval....
isn't the break in oil 5w30? .....that's what I was told at the service dept. (not that they're always right).
