Dearer than the current Opie Oils offer for same grade and spec Petronas oil.
Even with the delivery charge, its £10 dearer than the Petronas.
Old thread I know. Shell Helix Ultra has an additive called Tackifiers (hope I've spelt that right) which originates from the adhesive industry. It leaves a film of oil on all working surfaces. So yes, oil can be sticky.

According to Bob the Oil Guy nearly all engine oiks have had a tackifier for quite a while.

Quick question, my W212 is approaching 200k miles and Millers did an oil analysis on the oil removed at the last oil change 8k miles ago.
They suggested I could go up to 5W40 due to the mileage.
Is it of any benefit to do this? Their suggested oil is more expensive than that which MB supplies.
I will still be changing every 8k regardless.
Thanks

As a rule of thumb, a higher viscosity oil protects the engine better, while a thinner oil will yield better mpg.
On my other car (not MB), the manufacturer actually lists two oil types, I can either use 30 oil which is the standard oil, and then there's an optional 20 oil, labelled as 'Eco'. The car comes from the factory with the 20 oil, presumably in order to gain a few points on the CO2 emissions.
Personally, I would always prefer better protection over economy. However, I also think that the actual difference in CO2 emissions, mpg, and wear protection, are probably miniscule anyway, and any difference will only become evident in many miles of motoring.
I would take the garage's advice and go the thicker 40 oil.

Is their suggestion a low ash 229.52 (or .51 ) oil ?

Up from what?
Could they be more specific than that? What are they seeing in the analysis?

5w/30 , same as my om642
They may have detected excessive wear particles in the oil analysis although without them being more specific that's conjecture on my part. Hard to think what else they would have found to suggest thicker oil was necessary. What the 5W40 will do is increase your oil pressure which is a good thing if the pressure was previously too low. The minimum oil film thickness in rotating bearings will increase which again is a good thing. The cam chain in particular will also benefit from thicker oil.

Thicker doesn't mean better it's just a oil pressure adjuster .

It's also possible that the oil analysis found nothing wrong with the oil, however the tester mentioned 'by way of conversation' that high-mileage engines can benefit from thicker oil? I.e., the recommendation for thicker oil was generic, and not a result of the specific oil analysis?

And why is it important to have the correct oil pressure? To ensure optimal wear protection, would be my guess..........
It's this -
