Except for the 0w40, which is still a SJ rating, last I checked.
For everyone who doubted me...

<b>The great confusion at Mobil
Hi, all:

If you do not like to read about oils, please do not read any further as I titled it "The great confusion at Mobil."

I have been following Mobil's move on new oils very closely and I have posted to the effect (in this forum and several other MB and general auto forums) that the latest Mobil Delvac 1300 Super and, very recently, Mobil 1 Tri-Synthetic SL oil has deteriorated in specs due to the use of inferior (compared to the SJ formula) base stocks. Now I have some proof.

After all other major synthetic oils came out with the SL rated oil, Mobil released its Tri-Synthetic SL rated oil in late March. After it came out, people started wondering why a sudden increase in pour point (10 degree) and stuffs like that.

As of today, Mobil has apparently changed its product strategy. It has removed the product specs of the SL rated Mobil 1 Tr-Synthetic oil from its Website (at the least the link used to work did not work anymore). And the old SJ stuffs are back on the Website.

More importantly, Mobil started a new Mobil 1 SuperSyn series of synthetic oil and the Tri-Synthetic is listed under Semi-synthetic oils now.

More interestingly, please read this post form the Edmonds Townhall Synthetic Oil discussion. I provide the link and also the text below.

Mobil 1 SuperSyn

Well I saw this formula again today. The 5w-30 said it was for newer engines, the 10w-30 was for older engines and the 15w-50 was for high performance engines. It was ILSAC GF-3 and API SL rated and listed as meeting European ACEA requirements but I don't remember the numbers. There was no mention of "Tri-Synthetic" anywhere. only "synthetic fluids". The person stocking the shelves believed that this was replaceing the Trisynthetic formula. I looked throug Mobil's product data sheets but found no mention of the SuperSyn formula. I did notice that the Trisynthetic formula is now listed under the Semi-Synthetic Automotive Engine Oil group. see...

paste the 2 pieces together

Strange that it says "The Mobil 1 Tri-Synthetic Series motor oils are manufactured from 100% synthetic base stocks" but is listed under semi-synthetic. Has Mobil joined the dark side of synthetics? It also lists the Trisynthetic blend as API SL rated but only ILSAC GF-2 even though I had bought some MObil1 10-w30 SL oil that stated it was GF-3. I have been a long time satisfied user of Mobil1 but I'm becoming wary. Chevron Supreme is looking better all the time. Anyone have any insights into what's going on at Mobil?????
&gt;&gt;

If all this is true and Mobil did not make a mistake in their information, then the Tri-Synthetic oils many of us have been buying are really (. . . filling the blank here . . .) as some of us were suspecting after Mobil lost the law suit against Castrol on the definition of "synthetic." </b>

What you should be concerned about is how much wear is occurring inside you engine.

I think it was here that I saw the link, someone had their waste oil analyzed and the indicator metals were lowest when using Mobil 1 compared to other available oils.

I wouldn't really care if they are using elephant poop if that is what produces the best results.

Time for all you hold-outs to switch to Redline Oils.

PhilMason

Good stuff. Highly recomended

garreTTk

what difference does it make if it is a full syn or not if the amount of wear (metal indicators) in the waste oil is least with Mobil 1.

I'm not trying to bash or promote one oil over another (I don't have Mobil 1 in right now) but unless I'm missing something, the oil with the least metal in the wast should be the one to choose.

So SuperSyn is Synthetic and TriSynthetic is not? Did I follow right?

I wouldn't base my decision solely on the results posted by someone on a forum who got a single analysis of their waste oil, but thats just me.

I just know I've been using redline for years and years in all my vehicles, and it does the job. If you like mobil, use it.

Jason Chen

Can you post the link to where they tested the oils?

Why would anyone buy the full syn when we can all buy blends from Penzoil and get oil changes at jiffy lube?

(You knew I was going to add a smartie pants comments at the end :P)

Jason Chen

I don't think neither is fully synthetic anymore.
