I have been using Redline 10W60 for the last two oil changes. I have also been adding a bottle of ZDDPlus to bring the anti-wear ZDDP levels (Zinc and Phosphorus) up.
I just switched to Redline 15W50. (I hear the ‘BMW Engineers know better than you’ Nazi’s with their pitchforks and torches moving toward me now…..)
At a Porsche event at VIR last month, James Clay was there all three days. He was being a personal driving coach for someone. I did not ask how much THAT cost……
We had a discussion about oil for the S54B32 engine. His comments specifically said that he and his tech boys at Bimmerworld are seeing better bearing wear on the S54 using a 50 weight oil. Like I said in a previous post, my on track temps are 5-10’ cooler with the 50 weight oil than with a 60 weight.
My car has 38,000 miles on it. I received the Blackstone report last week. My ‘Lead’ level was at a staggering 43PPM and ‘Iron’ was at 17PPM. Remember, this report has been on 10W60.
I am concerned but not ‘going out of my mind’ like some on this board would do. There are several things that could cause this spike in lead other than bearing wear. I just have to wait and see. Just be to sure and to have all my duck in a row, I have talked to Randy Forbes and my local guy on doing a bearing replacement.
I plan doing another oil sample at 3000miles to see what the delta’s are.

A must read for those who like to dive into the oil properties, which might explain why the 50 weight might be better. Enjoy.
