Blend or GrIII ?

blends arent any good, as you dont know how much of the different types of oil are in the blend. It could be 1% synthetic and 99% dino oil. There is NOTHING regulating this.
Make your own blend by using 4 quarts dion oil and 1 quart fully synthetic.

That's a tough one, I think I'd rather take a group III than a blend if all things were the same including the price. I'd much rather get that Redline Drew posted for a buck and change over both of these though
I would use the GIII as a blend might be a GIII and GI or GII mix.
A good blend (SL Durablend 10w40 rated ACEA A3 for example) might be better than a poor Group III (no example). Valvoline has consistently told me their Durablend is 30 percent synthetic (surely Group III "synthetic"). For a 10w30 user I prefer Maxlife with its 12-22% PAO, a moderate blend that is not promoted as a blend, but a good performing oil (my experience being with SL of course).
Shannow,
I would prefer the Group III because I have seen from reading the UOAs the GrpIII oils appear to go the distance,
such as the Castrol GrpIII oils, they have good wear numbers and the oil held up for 10,000 miles,
I know there are a few Castrol 20W-50 UOAs you can find in the UOAs area, I am sure there are other GrpIII oils that have performed well.
BTW, with more BITOG members using LC in the oils, you are going to see better UOAs using GrpIII and Blends lubricants, such as the latest UOA for dino Havoline that was run for 10,000 miles.

Shannow, all other things never are equal. I'd take the one with the best additive package if I could determine that. I'd also consider who the blender was so I could gain some insight as to the quality of the add pak and basestocks.
I'd rather have a well formulated GpII+ than an el cheapo synthetic branded product of unknown quality.

The most telling indication of the PhillipsConoco synthetic blends' base oil quality is in the company's posted MSDS's. They're listed as containing "severly hydroprocessed" and heavy paraffinic base oils (although percentage ranges are no longer specified in the MSDS's). In the toxicology section, both types are certified as non-carcinogenic. "Severly hydroprocessed" is oil company-speak for Group III. Any conventional base stock that is non-carconogenic rules out Group I because of its double-digit aromatic content. So, by deduction, the ConocoPhillips stable of synthetic blends contain a mixture of Group II and Group III base stocks plus the additive package (which may or may not include minimal Group I as the carrier oil - not uncommon even for "full synthetics"). However, others have posted on BITOG that ConocoPhillips CSRs have stated in both telephone conversations and email replies that the Group III content is in excess of 50%. I doubt there are any "bad" SM oils out there from major refiner/blenders, but the ConocoPhillips batch seems to have the stuff to lay claim to being among the better ones. Until UOA's suggest otherwise, TropArtic at a buck-a-quart is the most bang for the buck I currently see. I'll give BITOG's new member, SE05, the benefit of the doubt - so long as he continues posting unsubstantiated opinions, I'll continue doubting them.
I remember specifically where we saw a few outstanding uoa's on Castrol Syntec Blend. I wouldn't think it is fair to say that blends are no good.
If you want to mix up Mobil 1 and Mobil Clean feel free, but I haven't seen proof that it's better than the fully formulated Blend.
Part of the problem is that "Synthetic Blend" on the label is just a marketing term and could be Grp III dino mixed with either Grp I or II, or it could be PAO mixed with Grp I, II, or III.
Mobil Clean 7500 & Schaeffer's are the only true blends that I'm aware of. As TallPaul often points out, Maxlife has 15% PAO, but is not marketed as a blend.
Back to Shannow's question, a good comparison would be the Mobil Clean 7500 PAO & dino blend vs the SuperTech Synthetic Grp III oil, with both about $2.50 per quart.
While I think the SuperTech syn oil is a good value for the price, I see the Clean 7500 as being a better performer especially for 6K+ OCI's.
