Does Mobil 1 0w40 REALLY clean?

[LonelyOilFunnel]

If so, does the latest spec (SP) still clean as well?
I’ve read a bunch of claims here stating it cleans out sludge and even varnish.
Any experience?

A few previous threads to get you started that are specific to that grade. There are many more. Also many more threads on Mobil 1 in general.

Cleaning is directly related to base stock composition. If you have an actual, verified problem with a dirty engine then you are better off using a product that is designed to clean. What is your actual issue?

Mobil 1 0w-40

I see M1 0w-40 mentioned here as a good choice for many engines and situations. However, I see that there are two M1 0w-40 oils: ESP and European Car Formula. Unless specified, how is an ignorant newbie to know which oil is being referenced?

I already use 5W-30 in my '22Limited (calls for 0W-20) and 5W-30 For my Forester XT (calls for 5W-30). We'll see how the UOA's compare.

Trav is talking about esp x2 in that post not m1 0w40?

So what is the problem with your engine that you're attempting to correct?

Cleaning. Oil can’t fix mechanical issues

 

[edyvw]

No it doesn’t. My LG washer is much better.

Cleaning. Oil can’t fix mechanical issues

Any oil that has additives, ESPECIALLY oil that has THOSE approvals, is cleaning.

with no before an after pictures what are we supposed to draw form the picture.
I was referring to his previous comment.

Common sense tells it depends on the amount and type of deposits, I cant see it cleaning a sludge monster in one go but I can tell you the 5w30 ESP cleaned up minor deposits and varnish under the valve cover in one OCI that lasted a year and 5K.

I think I'll stop now this falls under my "dont feed the trolls" policy.

Cleaning what? Sludge? Varnish?

 

[LonelyOilFunnel]

I see these are the current approvals, which one of these are you referring to specifically?

MB-Approval 229.3

MB-Approval 229.5

VW 502 00

VW 505 00

NISSAN Genuine Performances

Porsche A40

 

[LonelyOilFunnel]

yes, both sludge and varnish

 

[edyvw]

MB-Approval 229.3

MB-Approval 229.5

VW 502 00

VW 505 00

NISSAN Genuine Performances

All of them.
@kschachn will find you 2385 and some topics talking specifically about those approvals.
