£55 for 10L 😅😂

Ahh ok! I see the distinction now between permanent and temporary shear and how the VII play their role in this in various parts of engine. My original main concern was that of the 10w-30 causing premature wear to bearings due to oil film maybe not being adequately maintained but there is...

You're a star, thanks for helping me to understand better. I feel a lot better informed now :D Regarding the Rubia, I have about 20L of it currently and can get more 10w30 for almost give away price compared to buying other 15w-40 HDEO at £40-45 typical price for 7.5L. Thus if I use the Rubia...

Nothing quantitative, no oil analysis has been done, but will begin to from now on. Main bearing failure, oil pumps looking like I showed and chain snap seems to be becoming more common. How much of that is neglect accumulation from following BMW's ridiculous oci recommendations versus...

Yh i appreciate this. I have only been looking at the actual approvals granted.

I have been disregarding the recommendation by manufacturer. Just look at the approved list. I thought this to mean it's been run through the OEM test procedure for various parameters to be measured and passed. I thought the recommendation meant it meets stuff like min Hths, tbn etc values but...

The comma rep said (regarding the 5w50 Motorsport oil I attached data sheet for on page1); "Please find attached our TDS for Motorsport 5W-50, the ZDDP for our Motorsport 5W-50 is about 0.10% 1000PPM regrettably we do not measure hths and noack for this product." Don't measure, or don't want...

Thanks for your suggestions! Might be able to get hold of that here. Please may I clarify, I always thought of the TBN to mainly give indication as to how good the oil will "buffer" acidic combustion products over its lifespan. It seems there is more dimension to this. I.e. the additional...

Excellent information. Thank you very much for taking the time to post. I will read through Gokhans thread. I had a quick skim. Regarding suggestions, I will see which of those are more readily available here in UK (delvac for e.g is a bit tricky to find from quick search). If I'm...

The 10w30 HDEO I use meets MB approval 228.51. I found the following specs. Hths must be atleast 3.5 so it is atleast matches min 3.5 Hths of the BMW LL04

Turbo from a JD tractor, vgt type. This is the culprit in question, the source of many headaches!

Thanks for actual input. I currently use a 10w30 HDEO. It won't be anything popular in NA, but it's usually Total (this looks to be a blend) and Fuchs oils. Data sheet for the Total attached. I use these because I have inexpensive access to them so I'm able to change out every 3k miles...

Oil pump stators and rotors from running engines

That last part of your message, I think it was quite a strange reply. I was quite clear in asking for direction. I even took the recommendation to go by spec approval rather than simply trying to determine oil on its base composition and so I made alternative suggestion for consideration. I...
