Yes, that's a blend. And you know exactly how much of it is synthetic. With many synthetic blend brands out there, you don't know the actual percentage that's synthetic. The oil companies keep that from the public.
i think pennzoil syn blend is 50% syn and so they say
i dont know about motorcraft or the others

I saw that also they say its 50% syn.
Yep it works but probably just cheaper to buy the syn blend isn't it?
By definition that would be a synthetic blend. However, what you would have is an oil of untested formulation, so it would lose every single one of its specifications and approvals. That's not to say it suddenly loses all of its performance or can't do the job, but nobody's got your back if anything did go wrong.
What do you all think the major manufactures do? Of course they simply mix some of their syn into their conventional and call it a blend. While Pennzoil may differ, usually you get about 20% syn and 80% conventional. I looked into this.
You would get a better ratio if you mixed it 50-50. The 20-80 blends are not worth the price, IMO. No need to over think this, for the tiny price difference, just buy straight syn.

Yes it does and a lot of people do it. Maybe you should not do it while your auto is under a warranty, but after that, do it if you want to. Especially if you have opened parts of oil in your stash like many of us do. Mix it and use it. My cars have never had a problem with any mix.
Yes, I do it all the time at 40%-50%

Let me ask this question.
How much of the sold blends are mixed with Grp III synthetic with some PAO/ester mixed or are they mixing true synthetic PAO/ester components into the conventional at a higher percentage than they do with Grp III synthetics?
It would seem to me that taking a Grp III synthetic and mixing it with conventional will result in a conventional better conventional mix with a very diluted amount of true synthetic components.
I have no idea and often wondered about this that why I ask the question.
Nothing against Grp III it works well but it is conventional after all, mixing it with lower Grp conventional just seems like putting lipstick on a pig.

I don't think so. If you add a quart of Pennzoil SN oil to an engine that contains Castrol SN motor oil, it will still be SN and meet SN requirements. If this were not true, any time you added a quart of make-up oil that didn't match the brand that was in the car, you would void your engine warranty.

I don't know that answer either, so, as I said at the end of my post, I just buy straight syn.

Me too. For the small difference in price I cant see using dino or a blend. I haven't used it in anything decent since the mid 80's.
for the first 100K on my 05 Accord 4cyl, I mixed 4 qts 5-20 Castrol GTX with 1 qt 5-20 Syntec to make my own syn blend. Not sure if it was better than straight conventional, but it didn't do any measurable harm
The answers to the questions Trav posed would solve the puzzle--do the refiners just add more conventional to straight conventional, or are they actually intorducing real syn into the mix?
