Exxon's reply to me..

Guys,

You got a better chance of Kentucky Fried Chicken telling you what the 11 secret herbs in Colonel Sanders' Recipe is....

than ExxonMobil giving you a straight answer.

True enough. There is, however, a difference between asking for the secret list of all 11 herbs and spices, and asking KFC if there's any aresenic in the mixture. A somewhat flawed analogy perhaps, but I'm sure you see the point.

For those who question the factual basis for all this, I agree, though less so than last week. EM knows what's up here, and has repeatedly declined to clarify (verbatim of my last response from EM: "The information that has been provided regarding your inquiry is all that is available to the public. Their is no more information that I can offer regarding this inquiry. Sorry."). Hey, it's their rep to preserve or destroy...

I'm in favor of continuing to beat this horse, dead or alive. I think we should keep beating until we're standing in a cloud of bonemeal dust from the dead horse's dry skeleton. Those who are tired of it need not click into the thread. After all the years of hammering Castrol and insinuating that they (Mobil) were taking the high road, Exxon-Mobil deserves the harshest pummeling.

We may be just barely into the five-figure membership range, but word of this can, and will spread from a site this size. Just look at what the internet did to Toyota after their sludge debacle of a few years back -- without any 10k+ member sites priming the pump.

I completely agree. Mobil 1 dscussions have been a major part of this board and is probably the reason it was founded. Early on it was a syn vs non-syn slugfest. Seriously ..we have a half dozen threads devoted to this. How many threads do we have devoted to the g0d-like virtues of GC? Hink: I can't count that high.

I agree, this subject cannot be dropped. Taking away the mystery and revealing the truth about motor oils is what this site is all about.

So, having established 5w30 and 15w50 (both EP?), let's discuss Mobil 1 Turbo Diesel Truck 5w40/Delvac 1 as the next. That's, to a large extent, another whole separate customer base (though I can't seem to find any trucker forum discussing synth. oil).

Are there any indications or testing possibilities as to what that is made of at this point?

I just changed the oil in my VW TDI using Delvac 1, having last used the old Mobil 1 Truck and SUV 5w40 early in the year. After using GC much of the year and then Mobil 1 0w40 for a brief while before I located Delvac 1 locally, my little bit of anecdotal experience is that the car idles much less smoothly, stumbling a bit now and then. Of course it did also get cold just around the time of the oil change (southern Maine), but I never got this behavior last year, using Mobil 1 5w40. Would Grp IV vs. Grp III make a difference in high-20s weather?
Now I was about to spend $40 (and deal with a difficult store location/opening hours) for a 6-pack of Mobil 1 Turbo Diesel Truck for topping off as well as the next oil change in about 2 months. What should I do? How likely is it that Mobil 1 Turbo Diesel Truck is no longer as good as it used to be? Using GC, I do lose some Diesel-specific characteristics of Mobil 1 Turbo Diesel Truck, as far as I know; is that better than gambling that Mobil 1 Turbo Diesel Truck is still OK?

What is a good OCI with GC in a TD engine that prescribes 10k miles with 5w40 oil?

There are 1,515 pages of other threads for those who don't like this one. This one has my approval.

Only one sample was cited in the original post and the test, even if it was on 2 samples, hardly meets with established scientific rigor. We've turned the wires red on the flimsiest of evidence, with no control tests using known references, in an area of science subject to wide and varying interpretations. It doesn't make sense to me from a purely scientific perspective, but conspiracy theories are always a lot more fun and XOM is an easy target to poke...

Roger...

Two samples were cited giving results from 2 different grades of Mobil 1 Extended Performance oils. Both showed GPIII was very present. Both samples were compared to pure PAO and pure AN oil for calibrating reference. Also gives the date of bottling for reference also.

So now someone else is going to try to resample with a G.C. in relation to work for his PhD. so hold on to your hats and he hopes it happens soon too as it will relieve him of being the only one pointing this out.

Does he back of his claim nope, does he welcome verification YUP. So wait and see what happens.

 

[Ramjet Roger]

Whew! At over 700 posts, I missed the second sample. I'm still not sure that that limited GC testing constitutes a definitive indictment against M1 and even Tom NJ admits as much. But, I'm willing to concede that M1 has gone to ________ with Group III. Only odd thing. The new SM M1 non-EP versions of 5W20 and 5W30 actually appear to perform better in my applications. Gone is the notorious valvetrain clatter. Gone is the startup bearing thumping. Wear metals in my used oil analysis are reduced. Inside of the engine is clean as a whistle. So maybe the addition of thicker Group III stock is actually a good thing.

Just let it go and if you feel slighted then boycott mobil and move on. I think i have read 10 threads that has to do with mobil and their reply to the same question. Enough is enough.

Hey...if you don't care to read about the subject, just move on to other threads or start your own.

Well, I was switching from M1 anyway due to the price. I can find plenty of good oils out there and not have to pay the higher price for M1. I am using both Supertech Synthetic and Pennziol Platinum. Good bargains for my money and won't break the bank when I buy to replenish my "horde".
