Mobil 1 ESP X4 Euro 0w-40

[kschachn]

I tried it. Have you?

Perhaps it is related to the unique tolerances of Euro engines.

Ahhh, okay...

You move goal posts a lot. First you say it does something, then when asked about it you post something that says nothing of the sort, then it slides to the unknowable and unproven "it did it for me".

The VOA doesn't tell almost anything. I've used this oil before, and it's very good, and it even cleans carbon deposits and varnish. It has Mobil's latest generation of detergents and dispersants.

Unbelievable…..the hypocrisy

I see you’ve broken your “no‑engagement” vow yet again—drawn back, it seems, by the irresistible urge to toss another empty jab my way. If trading barbs is really your hobby, at least upgrade the equipment: flimsy quips and recycled outrage aren’t built to last, and they certainly won’t leave a mark over here.

So here’s a friendly suggestion: park the theatrics, polish a real argument, and circle back when you’ve got something sturdier than reflexive indignation. Until then, I’ll keep my focus on substance—and you can keep chasing echoes.

The problem is you don’t know why you keep getting called out.

That applies to you too. Nowhere is there any claim by ExxonMobil that the product removes varnish or carbon. All we have is that “it did it for me”.

If you would have picked on sludge or some other type of deposits then that would have been different. Varnish and carbon are not in the same category. Did you not notice that the picture you posted never mentioned either one of those?

There is a thread here corroborating that Mobil 1 ESP 0W30 does indeed clean sludge/varnish but there is no proof yet that it cleans those stubborn diamond-like piston deposits (That requires long hours of piston soak using a very strong solvent or a special oil molecule engineered to.unbind/break piston carbon as seems the case with Valvoline Restore and Protect)
ESP Family including 0W40 X4 falls under the same thing. Otherwise they would have included it in their marketing chants.
Mobil 1 does not say anything about piston deposits even with their new Advanced clean oil.

Thank you @fantastic for the VOA.
