I agree, a lot of baseless speculation. In one breath to have this knowledge of Mobil 1 formulation and the other he says we never know when they will change formulations, they are secretive. Well, that makes all synthetic oils suspect.
Amazing how many others sway with the discussion like sails in the wind (or is it sheep?)
It is true that some 15 years ago, M1 was not a full synthetic and had a notation on the bottle it was a full synthetic in a mineral oil carrier.
That changed and as far as I know has not changed back.
Amsoil used that info to put M1 down for years, then suddenly stopped.
Of course, they still say they are better (and probably are in some finite specs) than other syns..but considering any brand name synthetic is better overall than premium dino oil (which is probably good enough for 90+% of the cars on the road) the differences between synthetics is negligible IMO.
You can believe everything you read on Gore's internet, or you can believe all the hype the manufacturers put out. It is a great country, we have choices!

 

So did Cartrol Syntec and they got sued for false advertising.

Tests do not lie. Mobil 1 is not a Full-Synthetic anymore.

There are many other posts that show facts not just in that topic.

 

What tests? What facts? What posts?

 

Read that site.

 

I use the Delvac1. $30/gallon at my distributor, but IMO is it the finest oil made. I go 15K per change and the oil still looks and smells fine when I drain it. Shame really, probably could go 25K. The stuff is totally bulletproof.

Actually, I don't even use M1 in the G car, only because it started getting oil changes at a dealership using Castrol synthetic. And I like to keep using the same as long as it's a premium product.
But all my others cars have lived on M1 even when it was in it's previous 'truly' not full synthetic with a petroleum oil carrier. And conventional Castrol GTX in my RX-7 because synthetics are not advisable in rotaries.
That's several hundreds of thousands of trouble-free miles.
I have always believed, and still do, that good maintenance trumps fussing over different brands any day of the week.
If it comes down to getting your money's worth then I advise you check ingredients with a magnifying glass and have some serious discussions with a lubrication engineer before making decisions based on 'internet findings'.
It is very easy to draw false conclusions and make generalizations based on information that is not fully understood, even if the initial data is correct.
The only thread of truth of that might have some validity is the merging of Exxon and Mobil. That was unfortunate.
Prior to that time, back when Mobil was the 5th largest oil company they poured more profits back into R&D than any other. (Hell, they came out with M1 back in the late 60's.) I doubt that's the case any more.

 

Latest news: Out of the owner's manual for the Acura RDX (turbocharged sport SUV):

"Your vehicle is equipped with a "high-performance turbo charged engine" that requires the use of Synthectic motor oil. Always use Mobil 1 5w-30 or an equivalent oil that meets the Acura HTO-06 standard. Only use oils that display the HTO-06 standard on the label.
Failure to use Mobil 1 or an equivalent oil that meets the HTO-06 standard can lead to a reduction in engine performance or durability, and cause engine damage not covered by your warranty. "

What do those Honda engineers know!!! blaahhh

 

I put Royal Purple and K&N filter and my engine sounds more quiet....Royal Purple from now one, I didnt see that kind of difference when i used Mobil1

 

I use the Mobile 1, but the 10w-30

 

Yea sad part is that was before they changed the base stocks. Mobil 1 just changed them.

 

If Mobil did anything that causes them to fail specifications of several mfgs I am sure we will hear about it before too long.
Either that, or M1 will introduce a new formulation to cover HTO-06, etc. as inventories of the original one deplete.

 

They won't fail. They are just using cheaper materials to get away with calling it a synthetic now. It just won't last as long.

 

So if it meets the specs and the manufacturers' specific recommendations for change intervals, what's left?

 

I think that guy just has some personal vandetta against M1.

 

Well, I don't know. This controversy is all over internet. But that does not give it validity. I see a lot of skepticism which is better than accepting anything at face value.
But too much of it sounds like speculation not hard facts.
Either they meet the specs or they don't. If you don't feel comfortable using M1 there are many other options out there, no one is twisting your arm.
M1 has been factory fill on many performance vehicles. I find it hard to believe they are going to let themselves lose out on that market by going cheap on a process, when all they have to do is make it even better and charge more.
