It would make sense price-wise.
Rotella T Syn : 12.88$
Mobil Delvac 1300 : 5.88$
Chevron Delo 400 : 6.42$

Is Rotella T Syn Group III?

Yes. However, it is a higher grade than most Group IIIs. G-ManIII has posted extensively about this. You can do a search and find out more.
G3 is G3 no matter how you slice it. It's still hydrocracked dino basestocks.
G4 is the only way to go. 100% synthetic basestocks. G4 starts synthetic and stays synthetic.
Wrong on both counts. If we're talking about Shell's XHVI base oil, which is a Group III, there is nothing hydrcracked about it. The feedstock for XHVI is either waxy raffinate or slack wax, which are byproducts of crude oil refining, and these are isomerized into a base oil that has a higher VI than virtually any hydrocracked Group III.quote:

As for Group IV (PAO) starting out synthetic, the "building blocks" of PAO is nothing but ethylene gas, a purely natural substance that is a byproduct of CRUDE OIL refining.
So, in short the FEEDSTOCKS for both Group III and Group IV are the products of CRUDE OIL production.
Good info. Thanks...steve
The religious wars over what is a true synthetic or not are really rather amusing and amazing.
It all starts out as something pumped out of the ground. The question is how much processing has to be done to the input material in order for the resulting output to be labeled "synthetic" rather than "refined".
Of course there is real nonsense going on in the world of coal processing where US tax credits are available for making synthetic fuel ... and many companies get by with spraying some fluids on the coal in a secret process to wave the magic wand and turn regular coal into a synthetic fuel. You can read about this at many sources on the web, here is but one:
"Synthetic" Coal Tax Credit Article
The problem is in the very notion of a synthetic motor oil as distinct from a so called dead dino derived motor oil. Well guess what folks ... ALL motor oils trace their molecules back to dead plants and or dinosaurs which decomposed into crude oil and natural gas long ago.
If you want to be mad about marketing, get mad at Amsoil and/or Mobil for popularizing the notion that synthetic motor oils are by nature completely different exotic beasts.
In the end what matters is the performance of the product and the price it is sold at.
Synthetic Oil is really a misnomer all together.

I thought esters weren't produced from crude oil.
They aren't.
Also, here's some food for thought: We all want to dismiss Group III as being not a true synthetic. However, in the early days of gasoline production, when demand began to rise with the advent of cars powered by internal combustion, the oil companies had to develop a new way to produce gasoline since the amount produced naturally through distillation wasn't enough. What they came up with was "cracking" the larger crude molecules to produce gasoline. This "cracked" gas was commonly referred to at the time as "synthetic gasoline" and was universally lauded for its superior properties, including a much higher octane than "natural gasoline."
Hydrocracking involves the restructuring of the feedstock molecules to the point that they don't resemble their original state at all. It would seem, then, that the final product of hydrocraking can lay claim to being "synthetic"—at least in some sense of the word.
I respect Group III's, as long as they are fairly priced.
Does this make me a Hydro-crackpot?

I think it all comes down to economics. What will give you the needed protection for the minimum cost per mile.
What are your goals? Which oil meets that goal at the minimum cost per mile.
