Supposedly, the only TRUE synthetic Mobil 1 offers is there 5w30 and 10w30 synthetics. I will have to do a search on that new stuff...

Based on a lawsuit several years ago, US oil manufactures can market Group III oils as a 'true synthetic'.
Costs of synthetics vary considerably. The most expensive are the “Ester” types originally only used in jet engines. These cost 6 to 10 times more than high quality mineral (normal) oils. The cheapest synthetics are not really synthetic at all, from a chemists point of view. These are in fact specially refined light viscosity mineral oils known as “hydrocracked”. These have some advantages over equivalent mineral oils, particularly in lower viscosity motor oils such as 5w-30 or other oils with a low “W” rating such as 5w-50 etc and they cost about 1.5 times more than good quality mineral fractions.
True synthetics are PAO or Ester based and NOT hydrocracked...
This is the “synthetic” which is always used in cheap oils that are labeled “synthetic”.
Yes it’s a cruel world, you get what you pay for!
Now, you may ask, why are these special mineral oils called “synthetic”?
Well, it was all sorted in a legal battle that took place in the USA about ten years ago. Sound reasons (including evidence from a Nobel Prize winning chemist) were disregarded and the final ruling was that certain mineral bases that had undergone extra chemical treatments could be called “synthetic”.
Needless to say, the marketing executives wet their panties with pure delight!
They realized that this meant, and still does, that the critical buzz-word “synthetic” could be printed on a can of cheap oil provided that the contents included a few percent of “hydrocracked” mineral oil, at a cost of quite literally a few pence.
So, the chemistry of “synthetics” is complex and so is the politics!
The economics are very simple. If you like the look of a smart well-marketed can with “synthetic” printed on it, fair enough, it will not cost you a lot; and now you know why this is the case.
But, if you drive a high performance car, and you intend to keep it for several years, and maybe do the odd “track day”, then you need a genuine Ester/PAO (Poly Alpha Olefin) synthetic oil.
