mercon v flash point semi v full v zero synthetic

[merconvvv]

Wondering if flash point and pour point of a fluid will indicate how synthetic the transmission oil is as there are too many brands out there.

mobil 1 has flash point of 220c/428f and pour point of -51c/-60f

Motorcraft mercon v has around flash point of 196c/385f and pour point -48c/-54f

Conoco mercon v has flash point of 196c/385f and pour point of -49f

Coastal mercon v has flash point of 390f and pour point of -45f

Castrol transmax mercon v has flash point of 180c/356f and pour point of -35c/-31f

I am thinking that castrol is not even semi synthetic???
I have tried mobil 1, motorcraft and currently have castrol in my 99 ford expedition. Motorcraft provided the best shifting in my opinion.

The answer is, probably not, because components in the additive chemistry can affect flashpoint and pour point.

 

[merconvvv]

Why would a company add additives beyond what is required by the mercon v standard to degrade flash n pour points ?
Thats what makes me think it is about how synthetic the oil is prior to any additives.

I have found that flash point and pour point on information sheets can vary from the actual product. Some are "typical" and some are minimums or maximums. Did you have these tests run or are they from the literature?

 

[merconvvv]

Numbers are from msds info.

Looking at VOA for Schaeffer Supreme 9000 5W-50 I find the Blackstone lab report H27721 of 1/20/16 reports flash point to be 420 F. Looking at the MSDS the flash point is 440.6 F. This was the first oil I looked up today but I expect it to be typical.

 

[merconvvv]

I would think all msds "typical" numbers are some sort of an average and not based on one sample. Castrol numbers are quite inferior to motorcraft numbers which is not comforting to me at all. A bad batch of motorcraft might be closer to castrol stated numbers but a bad batch of castrol might really be eyebrow raising

I never said they would have additive levels beyond what was recommended.

If I have five different additive companies suggesting five different formulations I could have five different flash point results.

The point is, the old addage about base oils alone affecting flash points is moot.

Thanks molakule for the further clarification. I guess motorcraft has additives in their mercon v which my expedition transmission is smoothest with compared to mobil 1 and castrol.

It might be interesting to look at what the requirements are in providing SDS. I may be a cynic, but I have seen too many ridiculous ones.

MSDS information is for firefighters and emergency responders, not for anything else. The numbers that are being reported are close enough to let a firefighter know how to fight a fire. The numbers being reported are for the major components of mixtures as well, not necessarily for a specific finished product.

I used to write MSDS as a living for a company. The very last thing you want to do is disclose any proprietary information in the sheet, and if you can actually mislead to protect trade secrets then all the better.

Thanks kschachn. Very useful info.

+1 I agree completely, however I did not want to say misleading.

I got 160k miles out of factory fill. It still looked good said the shop. Magnet had some junk. Pan was still almost clean. Replaced factory pan with dorman pan with drain and plug. I am starting to think factory mercon v lasting 160k miles is pretty impressive. Hopefully 1999 factory mercon v is still what is in 2016 factory mercon v
