I'm not a big XOM fan myself, but you're just spreading rumors here. Either provide proof or shut up.

Hi,
Geo_Prizm - You said this:

"That is why even Mobil 1 is dumping mineral oil in the US market labeling it 'full synthetic'."

Please provide absolute proof that this is the case!

XoM are in fact creating other levels of lubricant (we call them semi-synthetics) around the World but maintaining M1 as a stand alone synthetic

Castrol have very clearly delineated their ranges too - just like Motul etc.

So Geo-Prizm, no rumours - no "bull" the facts please!

Oh, 'shut up' Quattro, you know full well that Mobil is not disclosing its Mobil 1 formulae.

You also know full well why Castrol is able to do the same here in the land of the gullible.

Do not tell me Mobil is different just because they sponsor the site.

Mobil 1 5W-30 (their number 1 product?) has ACEA A1/B1 qualification.

'ACEA A1/B1 oils are typically low HTHS (≤3.5cP) SAE 5W-30 based on API Group III base oils.'

Hi,
Geo_Prizm - Facts please, facts and data that substantiates your claim of "...dumping mineral oil in the US market and labeling it as "full synthetic."

Group III is mineral.

Hi,
Geo_Prizm - With due respect - supply all the facts that back up your statements with hard and conclusive data!

As a footnote, hydrocracked Group 3 lubricants are classed as semi-synthetic or fully synthetic depending on the Global location. The Wikipedia description may help you too - concentrate on VI for instance!!

Exactly, so how can you be sure what this formula is?


Just because it has low HT/HS does not automatically make it group III. Some oils are purposefully designed to have low HT/HS so that they can claim fuel economy improvements.

Again, unless you can provide us with laboratory results that specifically show M1 is group III, I think this discussion is pointless.

I know it is pointless, I just stated my view, I did not mean to codify anything. Unless Mobil provides us with laboratory results that specifically show M1 is group IV, I will continue seeing M1 as group III - mineral oil.

Doug_Hillary, I know... I have 6 or 7 qts of Mobil 1, I do not think it is a bad oil.Of course I will use it if I can not afford buying Castrol 0W-30 for my next oil change.

Hi,
Geo_Prizm - It would be helpful to all on BITOG if when you make statements such as you have - you can back them up. You haven't in this case and you can't!

As a relatively new BITOG contributor it is perhaps wise to be circumspect in your statements "as fact". Unsubstantiated opinions you are most welcome to

Oh, hi and thank you Doug_Hillary. I did not say what I say is law.And I do not have to add 'this is only my opinion' after each and every statement.This is a forum, obviously opinions are exchanged here, it is not a laboratory where we have to experiment to reach conclusive results.Even scientific studies tend to be refuted consecutively.

Well, you should. Otherwise, how are we to know when you're stating a fact and when you're just expressing an opinion?

And after all, an opinion should be formed based on some factual information. Among other things, what sets BITOG apart from other forums is that we try to deal with facts here. That's how we learn. Opinions are like a******* - everyone's got one.

Statements such as the one you made about M1 not being full synthetic have caused huge arguments here in the past, including some members getting banned because it quickly gets out of control, and it's impossible to settle these types of arguments since no one has the facts. So let's not even go there unless you're prepared to offer the facts.

Just my 2 cents.

So you will of course explain how you know they are dumping mineral oil in the US and labeling it full synthetic.

Someone found this.

Look under Korea and Japan. Not definitive proof in the USA, but Mobil 1 is not >90% PAO everywhere.

Hi,
prax - Correct - sometimes M1 products have a Group 5 content too!

This Thread is now a long way OT - it is really about the reasons why lubricants are different US and Europe

One prime reason is that the engine Manufacturers via their Association - ACEA - call the shots. In the US it has been the API and other Agencies and the Automakers have perhaps only played "catchup"

Sorry I should've been more clear.

MSDS will say "mineral oil." And not a little bit either. Also, some will only list a little bit of PAO and you know Mobil is not putting 80% Group V.

WRT off-topic: I was offering some proof that Mobil 1 is not PAO/Grp V only.
