Mobil 1 vs AMSOIL

As we talked about last night, sometimes it could be less and some times it could be exponentially higher. This is why trending is so important!
I pretty much agree also with previous posts. Which is why interpreting analysis results (an art, not a science) without at least three samples over the same mileage, same conditions and same oil on same engine is so important and knowing the analysis from a virgin sample as well. Looking at one sample, as we tend to do on most boards, is pretty much useless. Every engine off the line will wear differently. Which is why Blackstone's averages are also useless. Of course, that's my unprofessional opinion.
For most people (ave driver) oil analysis probably creates more potential problems/issues/concerns ( oh why is my copper 20 ppm higher then the ave and are my bearings wearing prematurely etc) then it can ever prevent. But, I still keep throwing money at it.

msparks,
Do you have any info on the Amsoil vs Mobil 1 test I was informed of?

I havn't heard anything about the tests yet. I'm sure when they come out they will be put on the comparison graphs when it does.
I dont' know much about this new supersyn. So I can't comment.
Though I will say that the Old XL 7500 is about the only close comparison to the old trisynthetic.

It didn’t do so well in the more severe 4 ball test scoring a .60mm scar. This compares to 037 for TSO. We’ll have more info coming up.
Ouch that stings!

Ever heard of the term "being politically correct?
Always compliment the oil good but unremarkable product. The baseline showed no “trick” ingredients, and appears to be simply the Mobil Tri-Synthetic with slight chemistry changes to meet the API SL standards:light duty 4 ball it scored quite well with a .35mm scar(less antiwear levels)
but then bring up the truth and weak points The TBN was a little weak: It didn’t do so well in the more severe 4 ball test scoring a .60mm scar(lower detergency? at least against amsoil it would be lower)(and how does the light duty 4ball score with other oils that produce .35mm?)
Maybe I'm looking at his statement differently but It seems to fall into what I had been saying so far. As a standard conventional oil maybe fine but doesn't compare to what the trisynth is or was.

I asked for details as to exactly what "light duty" and "severe" mean.
They show 3 different four ball tests on their site.
Four Ball Wear Test (ASTM D-4172 B: 40 kg, 75°C, 1200 rpm, 1 hour, Scar in mm)
Four-Ball Wear Test (ASTM D 4172: 40kgf, 150°C, 1800 rpm, 1 hr) Scar diameter, mm
Four-Ball Wear Test (ASTM D 4172: 60kg, 150°C, 1800 rpm, 1 hr) Scar diameter, mm
I'm assuming that the first is the light duty.
Amsoil's 5W30(ASL) and 10W30(ATM) synthetic also score a .35 on this one.
Their XL7500s score a .40 on the second one with the 0W30(TSO) scoring a .373.
One thing I wonder about... Why don't they use one four ball and stick with it? Then you could get an appreciation for each oil on a consistent basis.

I give up, what is TSO?
TSO is the stock number for AMSOIL Series 2000 0W-30
Hmm, Amsoil says SuperSyn is good but unremarkable, basically a slightly modified TriSyn. I guess it all hinges on just how significant those "slight chemistry changes to meet API SL standards" are.
Well, Amsoil saying it's "good" is significant in itself.

I agree wholeheartedly
Mobil 1 is a very good product, however since they are formulating it to sell @ $4.00/qt, they are somewhat limited in terms of the basestocks and additive chemistry they can use. The Delvac 1, 5w-40 synthetic diesel oil is a better (but more expensive) product, with a more robust additive package.
There is no secret to making a long drain synthetic oil - it is simply a matter of $$$$ and experience.

I wish I could buy Mobil 1 @ $4.00/quart. It sells here for $4.80 to $5.00/quart depending on where you go.

Come on up to Canada! We've still got boatloads of the TriSynthetic Mobil 1 for $6.35 per liter up here (or $5 a liter if you find the 5L jugs!) and at $6.35 per liter that's about $4US. Of course it would cost you more in travel expenses to get here, but you guys could visit the Patman while you're up here!
I'll buy you a beer!
I got a reply from Amsoil.

What are the details of the 2 different 4 ball tests?
Thanks,
Wayne
-------------------------------------------------
So, Mobil 1 SuperSyn has the same four ball as Amsoil's regular synthetics, but worse than their Amsoil 2000 and XL7500.
I wonder if the results for the XL7500 are from the PAO based, or the new Group III based oil.
Considering that Amsoil's regular synthetic oils have the same price as Mobil 1, at about $5, this is not that bad. The 2000 goes for about $8 a quart.
