quote:That has been our speculation, here, since last July, when the new ConocoPhillips GF-4 blends were announced. However, I'm now going to hop off that bandwagon. Looking at the terminology in the new Trop Arctic MSDS, it is 70-80% hydrocarbon base oils & the remainder listed as "proprietary additives". This actually means that the Grp III component, that warrants the use of the synthetic blend label, may only be present in amounts down to 15-20%. Also, the cold crank rating, as I recall was originally about 4500 cP for the 5w-30. Now it is 5300 cP on the latest data sheet & this is matched by many GRP II+ formulations. The GRP III base oil in Motorcraft is a lower cost GRP III imported from Korea and identified on the Motorcraft MSDS as 62742-54-7, the same CAS number used for the Korean/S-Oil GRP III base oils. I now believe that the Motorcraft formulations have a higher percentage of G-III base oils than Trop Artic. The sell price is a bit of a clue - I would expect Trop Artic to sell in the $1.52/quart range if it indeed was the same formulation as Motorcraft.
So is it the exact same as MC?
quote:Not so fast - According to the ConocoPhillips MSDSs, in the toxicology section: "Carcinogenicty: The petroleum base oils contained in this product have been highly refined by a variety of processes including solvent extraction, hydrotreating, and dewaxing to remove aromatics and improve performance characteristics. All the oils meet the IP-346 criteria of less than 3 percent PAH's and therefore none are listed as a carcinogen by NTP, IARC, or OSHA. [emphasis mine] The only dino base stocks that have this low an aromatic content are Group IIIs, which in turn leads me to believe that a variety of base stock quality grades are used per availability and then thrown into the hydro-cooker to render them to Group III final status. This could be done in Korea, making the ConocoPhillips stable of brands virtually identical to Motorcraft. The latest product data sheets from ConocoPhillips are dated 03/05/05. Is it possible the company switched testing procedures from last September? The latest MSDS sheets from ConocoPhillips are dated 02/22/05, but Ford's is dated 04/11/05. Could the ConocoPhillips MSDS sheets represent a transitional spec that is now finalized in the Ford MSDS?
