Honda V6 engines and synthetic oil

if i'm wrong, mobil's msds filings are wrong. i'm happy for you to show me otherwise, but you need to cite credible evidence.

I can see you believe in conspiracies. Exxon will not divulge exact numbers for reasons other than what you want us to believe. The below is what YOU want us to believe.

"10w-30 mobil1 is only 5% "synthetic"

dude, read the msds. it's a legal filing. it says 5% pao. don't you want to "believe" that?

As are one line responses sans trimming.

It does not say PAO's or poly alpha olefins are 5%. It says the POLYOFEFIN POLYAMINE SUCCINIMIDE, POLYOL is 5%

The below, about Exxon product number 481176-00 MOBIL 1 10W-30 and its MSDS being #194095 is quoted from this link:

The POLYOFEFIN POLYAMINE SUCCINIMIDE is a cyclic organic compound with nitrogen and oxygen added. Think ammonia blended in with the oil, not the stuff you want to drink with cigars.

eh? "ofefin" is a typo. look it up.

Does it matter?

It's a quote. Would you like me to modify the quote?

The real substance of this thread is you are reading the msds wrong. POLYOFEFIN POLYAMINE SUCCINIMIDE is not poly alpha olefin

it matters in that you didn't understand that it was a typo!

no, i want you to find a quote that is authoritative, not from some knuckle-head on a car forum that thinks an amine is the same as ammonia!

no, it's a succinimide amine of polyolefin. the polyolefin is the backbone of the chemical. the other stuff is just fluff that affects molecular weight and perhaps surface adsorption properties. the "alpha" is just morphology. in the absence of iupac nomenclature, you can't say for sure /what/ it is.

Indeed, anyone 'skilled in the art' would recognize this as a misprint of 'polyolefin'.

Compounds of this sort are usually employed as dispersants or emulsifiers.

They mean POLYOFEFIN

POLYOFEFIN exists. See links below

let me get this straight:- you want to /ignore/ federal govt chemical compound database info in favor of typos from cheap chinese manufactured goods? ok, time to move along...

Let's get this starlight. You won't admit that Mobil 1 is primarily a PAO based oil. Instead all you want to do is argue about a supposed typo in order to deflect the exposure of your mistaken interpretation of a msds.

jim may be right here about the typos. Take a look closer to the bottom of the first link you gave, where it says "Caster Specifications". There I find the notation: "Wheel Type: Polyolefin".

When I Google for "polyofefin" or "ofefin", I find very, very little, mostly automated "on-the-fly" pages that result from Google's deals with advertisers.

with respect, there's /nothing/ on the mobil web site that tells you that. they tell you it /could/ be, but not that it is. thats the legal fine line. and the msds confirms it - if you know a little chemistry and can spell.

if you can cite any authoritative analysis on this subject, i'd love to see it - appeals to "belief" don't work.

Sure there is, try this :

Is Mobil 1 with SuperSyn Technology a fully synthetic motor oil?

Yes, it is. To meet the demanding requirements of today's specifications (and our customers' expectations), Mobil 1 with SuperSyn uses high-performance fluids, including polyalphaolefins (PAOs), along with a proprietary system of additives. Each Mobil 1 with SuperSyn viscosity grade uses a unique combination of synthetic fluids and selected additives in order to tailor the viscosity grade to its specific application.

POLYOFEFIN is a PROPENE POLYMER. See the msds below

POLYOFEFIN in cellular form is the dielectric in some coax cables.

With the introduction of "propene" to this discussion, I am now prepared to believe you that ofefin is an actual substance, not just a typographical error.

I found this -- rather abstruse and dense -- document:

It appears that olefins and ofefins are closely related, but are different, sort of like you and your sister.

i discussed that article in detail. why do i have to repeat myself?

ignoring the fact that "ofefin" does not appear to be cited in any chemical compound databases, that article cites "internal ofefin" once and "internal olefin" 20 times. all in the same context. i therefore stick with typo. but i asked on sci.materials.
