Doug Hillary (co-developer of the TWS oil) confirmed it over on BITOG and I tested it myself on our machines from Shell and agree with what he said.

What SFP was saying was that there are two different Edge TWS formulations, the FST for general retail, and the "Professional" FST exclusive to BMW dealers. If that's the case, that would mean Castrol has 3 different 10w60 oils, the Edge Sport PAO based, then the two ester base oils, the normal FST, and the BMW-specific Professional FST. Supposedly, the "Professional" oil has better quality. That is what I personally doubt. It seems pointless, wasteful, and cost prohibitive to have separate refinement and processing facilities to make the same oil with one of those facilities just a bit more thorough in quality control just for the sake of keeping BMW happy. Without evidence, I am assuming that the whole "Professional" naming thing on the label is just branding and marketing, nothing more. I'm thinking that this branding is part of the exclusivity agreemnent with BMW, that only oil sold by their dealers can be labelled "Professional", therefore Castrol removes that word from the label on the version of the oil destined for general retail. |

I get that it might seem unlikely but you shouldn't underestimate the rings that Castrol will jump through to keep their OEM first fill supply contract in place...its millions of gallons of oil a year and a contract that any oil company would cut off its corporate left testicle to steal from Castrol. I believe that Kawasaki was referring to an oil that in the UK was called Castrol Edge Sport 10W60 which sounds similar but was a different oil and didn't carry M engine approval. This particular brand name has now been discontinued probably to avoid confusion (using the word "Sport" made it sound like a better oil than the standard Edge 10W60 rather than being an inferior one). It doesn't help that some markets seem to have different names for the same oil. [1] Edit I suspect that Castrol wouldn't really want it known that the retail version has been superseded by an improved formulation and hence their reticence to discuss it. Which would fit in with the first post which notes the difference between the two oils. It does seem that Castrol Edge (TWS) remains the original formulation, is still approved for M engines and is retailed....while the Professional version is an updated formulation and is only available from BMW Last edited by SenorFunkyPants; 03-04-2014 at 06:49 AM.. |

http://www.ecstuning.com/BMW-E92-M3-...ice/ES2580488/ This is still labeled as "Professional" but is not "Genuine BMW" oil and is a few bucks cheaper than the bottle with the BMW label. What are your thoughts on this?

What puzzles me though is that some Castrol Edge TWS 10w60 bottles are labelled "Professional" and some aren't. I thought the "Professional" label was exclusive to the BMW-labelled version, but apparently it isn't. maybe it's different geographic distribution or possibly old labelling. |

I just found this link. It seems to confirm my hypothesis that the "Professional" label is "exclusive to OEM new car dealerships"
http://www.castrol.com/castrol/secti...tentId=7076437 Maybe the "Professional" ECS has is intended for a non-BMW car dealer? |

English spec sheet: http://msdspds.castrol.com/bpglis/FusionPDS.nsf/Files/BBCC7FDE12E7F0BC80257C9F00354631/$File/BPXE-9HD6GW.pdf FST is the name for their titanium add-pack. They don't use that branding on bottles in the US, but if you look at the regular Edge Professional TWS datasheet you will see the specs are identical: http://msdspds.castrol.com/bpglis/FusionPDS.nsf/Files/C746D41872AA21F880257BAB002E4C5E/$File/BPXE-99R6P4.pdf Therefore, the oil you linked to is exactly what we already have in our cars.
