Which synthetic blend has the most "synthetic"? Is there a comparison chart that shows how much each "blend" has?

Sure, sure, but what have you really accomplished by mixing two dis-similar additive packages?quote:
The blend that you make yourself. Honestly don't bother with synthetic blends. You get more for your money by mixing synthetic and dino yourself.
Ever seen any proof that invalidates it? Oils are made by design to be compatable with any other oil (ever read the back of an oil container?). I highly doubt that by mixing a syn and a dino there would be any adverse effects.quote:
I acknowledge that this "mix your own blend" advice is commonly trotted out, but I've never seen anything that validates the practice.
Well, here's a good example.quote:
I'm running 2 Honda Accords on 2 qts M1 5W30 and 3 qts of Havoline Dino right now.
He could just run Havoline on a 5000 mile OCI and fugheddaboutit.quote:

Same here...TropArtic is a good SynBlend and is my ooc for now. Contrary to Gilitar's comment, it is certainly not a waste of time, probably has a fairly high synthetic (perhaps even as much as 50%, GIII?) content, and has good overall numbers...I'm happy so far, but my UOA in a few weeks will hopefully confirm my beliefs.quote:

When I called ConocoPhillips consumer hotline shortly after their various brands' synthetic blends were introduced in November, '04 and asked that question, the female voice at the other end said the exact numbers were proprietary but hinted strongly that the synthetic content percentage (assuredly Group III) varied from the low 40s to just under 50 depending on viscosity grade. Keep two things in mind: 1> no way to know whether Miss Information was holding a broom handle in her other hand, or, 2> whether ConocoPhillips has since reformulated the oil. That caveat stated, I still scarfed up all the TropArtic Synthetic Blend I could lay my hands on at Dollar Tree last August. I'm finishing up my first 3,000 mile run with the stuff in my '03 Hyundai 2.7L V6. The engine's at least as quiet as with the older Chevron Supreme SL 10W-30 I had been running and the fuel consumption is at least as good, too. I plan to submit a sample of the 2nd run of T/A, but with my limited driving, that probably won't be until January, 07 at the earliest.
That was not refering to you particularly, I know you did not say it would destroy my engine, but others here have taken that approach. Only the stuff after your quote was really aimed at you.quote:

I kinda agree (and basicaly said so in my last sentence).quote:
My statement is still the same - "Are you gaining anything?"

Wouldn't it be more of a concern to know which oil performs better on a whole, not just some useless speculation about the blends formula?quote:

Wow, that's quite a story...do you write children's books on the side?quote:

I never the saw the point in synthetic blends from the consumers' standpoint. If you are cheap, get a dino oil. If you aren't cheap, get a full synthetic. It seems to me that there shouldn't be a fine enough distinction in cheapness for there to be such thing as a "semi-cheap oil buyer". I'm sure that the history of this is that some genius in the marketing dept of an oil company decided to diversify their product line by adding a "sort of synthetic oil" in the hopes of making more overall sales. Then his co-worker, who is better with wording than he, suggested the term "semi-synthetic" in place of "sort of synthetic".
