I'm impressed with what they sent me.. QUICK service (If I'd go to my PO Box more often, we would have had this up a week ago.. Sorry!)

Thanks again to Butler CAT for the tests!

Wuud 'ja like suum salt wiff 'dem fries?

Sodium used to be loathed in oil analyses,now it's almost getting common.
Like Bill said,Thanks Stinky for the great VOA database we're building!

sully · Mar 3, 2005

Well now, I have to wonder about the VOA I had done by Blackstone on the Mobil 5000. According to Mobil the 7500 has 18% more cleaning additives than the 5000.
5000 7500

Moly 64 117
Boron 44 69
Sodium 218 263
Calcium 829 1710
Phosphorous 341 632
Zinc 347 709

Well the sodium and boron are about 18% higher.

sully · Mar 3, 2005

O.K. one more comment and I'll shutup(to much coffee this morning). I certainly don't know much if anything about how these add packs function in an engine, but if this oil is a Group III/PAO blend and it's additives prove to function well in the long run.(sodium?)Then it may be quite the deal. Walmart is selling this oil for $2.18 a quart. IMHO.

You might already be aware of this, but for the newbies, according to a reliable source, the Sodium is due to an Antimony additive, which is a good thing.

Guess why I do uoa's? I have a GM engine.

I know this is a good oil, but I'll avoid for now. It would confuse me in trying to spot potential coolant leaks.

Thanks a lot Bill. Great work!!
If the add package proves itself, this oil is going to be almost unbeatable!

goodvibes · Mar 4, 2005

On the surface this oil looks better built than M1 EP. It's got the moly, boron, zddp, etc. of M1 EP but adds the antimony (if that's what the NA is) of the 5000. Perhaps it has to do with what mixes well with the base stocks. Looks like everthing works here. For what it costs, I would seriously consider 1/2 the interval with this stuff and maybe be doing my motor a favor at the same time.

Bill in Utah · Mar 4, 2005

FYi;

Na = Sodium

If anyone wants to host the scan of what Mark sent me, Please let me know and I'll scan it and email to you.

Thanks, Bill

goodvibes · Mar 4, 2005

Thanks, but I know which element Na indicates. I was referring to Na as being a possible component of antimony to indicate it's presence in an oil. I don't know if that's valid and therefore my questioning of it but it seems that some here think it is.

Fully Formulated Oil prices for various basestocks:

GP-II, approx $1.50/qt and up ...

GP-III "synthetics, approx $3.50/qt and up ...

PAO synthetics, approx $4.25/qt and up ...

A GP III/PAO blend for $2.20/qt? The numbers just don't add up.... I'd say probably more like a 30% PAO/70%, GP-II petroleum oil. This approach is very popular in Europe and you can make an ACEA "A2/B2", or SL/CF oil using this type of blend, with enough detergency for light duty diesels.

Using 30% PAO gives you the same performance as using about 70% GP-III in the blend.

Bill,

Did you happen to get the TBN for this oil?

This subject has been covered before and the information is this is a GRP III oil.

I do not see it on the report. Butler CAT sends a nice report to you via US Mail. Fast turnaround!

Thanks, Bill

Hirev · Mar 6, 2005

Thanks for the information Bill. Can't wait to see some UOA on this oil. It may be one of the best deals in PCMO out there.

Not to start anything here, but where has it been covered before that the new Mobil 7500 is Group III. I mean besides the anecdotal information provided by some, where's the definitive proof (Product Data Sheet or MSDS) that would provide irrefutable evidence?

sully · Mar 6, 2005

I will call Mobil Monday and see if this can be verified. I have no definitive proof at this time. Sorry if I led anybody astray on this subject.

guile · Mar 6, 2005

sully,

Didn't mean to imply that you lead anyone astray ... I've also read (several times) on BITOG that the new Mobil 7500 is Group III (w/PAO), yet no one offers any real evidence. I guess it just sounds "too good to be true."

If 7500 is mostly Group III (w/ some PAO), then seems it would be at least as good as Castrol Syntec (USA made), and as such, a great bargin.

sully · Mar 6, 2005

No problem Guile, I didn't mean to infer that it was Group III, but that the information presented so far indicates a strong possibilty. And some wishful thinking on my part. I did stumble across the MSDS sheets moments ago. For search criteria type in Mobil 7500 and/or M1 Extended Performance. Product code not required. Let me know if this helps in our quest for truth and knowledge.
