This was the case for S38B36 and S38B38 engines, but M88 and M88/3 parts were in 2009 already very rare. I used my entire network back to source parts across Europe. Some where found, but only complete engines that needed a rebuild anyways and since I wanted to maintain matching numbers and there was no warranty, this was not an option. In the end I traced a s/h M88/3 head from the previous business partner from member Euro-M5, but also that one needed serious work. I bought it as a reference and back-up plan, but that was it.Don't get me wrong the person who did the job may be done very clean and good job but in case of human Error that is Unacceptable in case of a failure, Raymond !!! At the time period of your rebuild at Ebay.de was flooded with M88 heads.....also UK junk yards who are dealing with BMW engine as well.
Its not like now days were the M88/S38 parts are slowly disappearing...
I had 528i with M52b28 engine, near same as M54. I used 15w40 no problem. It had 330000km when i sold it. My brother has 530i also, now over 300k km. He also use 15w40 oil and no problems. I try to take oil sample and sent it to lab.Q3: Does the M54 also benefit from a higher viscosity engine oil, e.g. a 10W60 grade ?.
I quite like Penrite myself. I was using Shell 15w50 semi synth for ages, but they recently changed formula and the zinc dropped from 1200 to something ridiculously low (i forget exactly).. so I did some research and currently In my M5 I'm using Penrite HPR-10 which is a fully synthetic 10w50. Also in their "full zinc" range. They have a good techncial bulletin on ZDDP on their site. I try to buy it in 20L bulk when on sale so it ends up pretty cheap.Sorry if this is the wrong thread for this.
I'm about to do a change on my S38B36 and given TWS 10w-60 has been discontinued (and is now priced here as if it were actual liquid gold, nearly A$20/Ltr..).
I'm considering two oils at present, both the factory spec'd viscosity 15w-40:
Liqui-Moly 15w-40 High Tech Touring (No idea on zinc, but should be 1000ppm or so given ACEA B4 I'm lead to believe...)

The other, from an Australian company is the Penrite Semi-Synthetic 15w-40 (Full Zinc).
SEMI SYNTHETIC 15W-40 (Semi Syn.)
EDIT:
Could only see VANTAGE 15w-40 available in stores.. -> VANTAGE SEMI SYNTHETIC 15W-40
One of my local shops was running a 30% off deal, so grabbed a 10L tub, $5.80/Ltr, worse case the W124 260E can burn through it.
I will be sending off for analysis a sample of the current oil (Probably edge 10w-60 given the workshop who serviced it last) and again at regular intervals.
I have access to Liqui-Moly at good prices through a friend, so if the above 15w-40 or their 10w-40/10w-60 is suitable oil please let me know.
Also, given I don't rack up the km's on my M5, what's the recommended change interval by time?
Brad Penn has always been on my radar as it has excellent specifications and your results proof that it has excellent performance as well.This was my first use of Brad Penn since owning the car. I am running my usual Valvoline 20w50 as I wanted to see results before deciding whether or not to continue with the Brad Penn semi-synthetic. Based on the Blackstone report it seems like a good reason to switch. What do you think?
I did actually, but demonstrating the process (how to) is not the intention of my contribution, which was merely aimed to scientifically proove the usefullness of Used Oil Analysis as an early detection method for critical bearing wear.You got stock size bearings and did not measure?
