Anri - I think like a Yorkshire man, ie, I dont spend money replacing items that don't need to be replaced, they just need a clean out to allow them to function correctly.
During my holidays, I gave this some thought and I think I need to share some additional info.Damage is their and done by previous owner/s not during your ownership, period.
TWS with half a bottle (8 oz i think) of redline engine break in additive (high zddp content) gave me great zinc phosphate numbers and really good used oil analysis results, so don't knock it. :deal:But hey, if someone gives me a case of TWS, it'll be in my engine tomorrow.
The oil change log of M88/3 engine with s/n 42243748 is as followsI am looking at your M88/3.
How many oil changes you had since the rebuild ?
If I am not mistaken you have 2 oil changes.
You had 1st oil using Mineral and then you moved to TWS Castrol as shown in your lab test.
Actually 6109km on the third oil change, in accordance with the break in scheme from Dick Hoekendijk when he rebuild his S38B38 engine from his track-prepared velvet E34 M5 (a.k.a fat-lady).On your Second oil change you drove 6100km with the TWS.
True, that is why we are reducing the oil change interval for M88/S38 to 6000 km max.My point earlier in my replies proves the Important of shorter oil changes regardless of an engine is rebuild or not.
Agreed; we now know that the S38/M88 break-in period lasts for much longer then the initial 5000km !On my fully rebuild S38-B36 engine I will continue to use Shell Rotella T for Diesel and gas engines until I see the Metal numbers down and wash off. As we can see from these facts its a waist of money to use such an expensive oil for break in period and also it will clean the system much faster with no metal inside the engine parts.
This oil is not available in Europe. Besides that, my experiences with continental Shell lubricants haven't been that positive.Additives:
The Shell Rotella T Diesel has about ~1150-1200PPM Zink, I have dropped another 300ppm using RedLine Zink additive so its shows almost 1600PPM ! but I feel comfortable with that number from Brand New engine.
Agreed, but when an engine has been run on Synthetic's, returning to mineral imposes a risk to seals and gaskets.As we can see their is abosolute no point of using synthetic oil on your dad's M30 E32 735i. This oil is absolute enough for the M30 need
Agreed.We will have super tight information regarding engine ware metals from fully rebuild.
We are aware that every engine wares differently than other but the most important is not to Micromanage each engine its the General Picture and concept to follow.
Thanks Anri, but I am not surprized. :grinI am a bit shocked !
As we can see the LEAD is '0' (Zero) :eek
First when I sow this I said to myself this is an Error from BlackStone.
After my call to the rep he said it’s not an Error !!!
That put a big smile on my face and he even mentioned that this engine is super healthy!
Raymond it’s your turn to post Lab Test on your M54 engine to compare.
True , I've also been noticing the number of posts dropping as E34 owners migrate to E39s , E60s and F10s over the last 2 yearsI am afraid when another year pass or so...their will be several people hear and that is it...
