GTX is not their flagship so I don't know if that 9.0 is worth it
I compared what you are showing me here to mine and all I can find is the vis. # we are looking at and also, yours says 0w-20 SP and mine just says 0w-20 without the SP Evidently the SP is thinner for some reason. Are you in the USA?

Check comment #44
Well, I don't know, but their Edge products are both thinner, and I want the thicker, possibly making it a little quieter and seem a little smoother. I am only going to do 3000-4000 mile or 6-month oic anyhow.

How do I check comment 44, how do I find it? I am new at the Bitog thing.
I figured it out.

Sad thing is, I was serious, but I figured it out even before you sent me the picture! LOL!
Do you know what the initials stand for jcp?
Figured it out, the api ratings.

Castrol GTX is a syn blend. If you want to compare datasheets claims for cSt to other oils mentioned in this thread, Castrol Edge is a Full Synthetic and therefore a relevant comparison.
Tested cSt IRL VOA is another matter since test results with most brands differ from datasheet claims.
I'm personally most familiar with 5w30 & 10w30 oils. I compared all the Full Synthetic and blend oils in those grades that are readily available in USA. Especially the HM ones. I looked at datasheet claims and VOAs (all by one lab - Oil Analyzers).
Edge HM 5w30 is thinner than several other good HM choices. However, Edge HM 10w30 looks really good because I like its cSt. So Castrol Edge HM has great cSt if I go up a grade from 5w30 to 10w30.
Edge HM 10w30 cSt has approx same cSt as Quaker State High Mileage Full Synthetic 5w30. I could be happy using either of those oils in my 97 Buick, but Edge HM costs $5 more.
Valvoline Extended Protection High Mileage 5w30 is another good oil with almost as high cSt, but costs $9 more .
Amsoil HM 5w30 is another good oil with similar cSt, but costs $20 more.
Of all those FS oils I just mentioned, Amsoil has the highest cSt at KV100, followed closely by Quaker State High Mileage Full Synthetic, which is then closely followed by the other two.
That's pretty much it for brands of oil with good cSt @ KV100. At least without going to Euro oils. It's defineately it for brands of HM FS oil.
Those brands of HM FS oils have good cSt and I'd be happy using any of those, but Quaker State High Mileage is by far the most affordable of the excellent HM FS oils that have good cSt.
Then look at Quaker State FS (non HM). Same excellent cSt, but without the extra seal conditioner. Then look at Quaker State UP FS and it has even higher cSt. Quaker State UP FS has highest cSt of any non Euro Full Synthetic AFAIK. I'm referring to IRL tested VOA cSt @ KV100.
Quaker State oils not only show high cSt in their data sheets, but also test showing higher cSt than claimed in the data sheets. What other oil does that?
Then consider the $20 (or less) per 5 qt jug price at Walmart for Quaker State FS oils. In the case of Quaker State UP FS also consider it claims to be a 20K mile oil.
Does it live up to it's 20K mile claim? I don't know. Maybe. I do know that in VOAs it exceeds its data sheet viscosity claims, which you can't say about any other brand that I know of. I think it's one of life's rare bargains. Just like Walmart car batteries have been cheaper and superior to most others.
It's a $20 a jug oil that competes with $30 & $40 a jug oils. It's debatable whether you can find a better non Euro oil. I think not. What is not debatable IMO is that Quaker State UP FS is a bargain. You won't find a better bargain, IMO. Same with Quaker State High Mileage Full Synthetic.

P.S. - I'm not even using Quaker State oil yet. I'm happily using Maxlife Blend. However, now that my oil leaks are gone, next time I want to use a High Mileage FS oil.
In order from highest cSt to lowest cSt @ KV100 based on VOA tests by Oil Analyzers... I could be very happy using any of these:
Amsoil High Mileage 5w30 (excellent/highest cSt, but $40 a jug, haven't seen on sale)
Castrol Edge High Mileage 10w30 (excellent cSt, $27.48 a jug, often $24 on sale)
Quaker State High Mileage FS 5w30 (excellent cSt, $23 a jug, often $20 on sale)
Valvoline Extended Protection High Mileage (FS) 5w30 (excellent cSt, $29 a jug, haven't seen on sale)
Those ^ 4 oils have higher cSt @ KV100 than any other 5w30 High Mileage FS oils on the market AFAIK. I compared all brands of High Mileage Full Synthetic and blend oils data sheets and all VOAs by Oil Analyzers.
My point is that after researching every brand of High Mileage oils for weeks. Those ^ are the best/thickest (at KV100 op temp) High Mileage Full Synthetic options that I could find. One of my criteria was the cSt at KV100 had to be high, but within grade. Edge 10w30 fits right in with the 3 best 5w30 brands. Edge 5w30 is too thin for my preferences, but Edge 10w30 is dandy.
Of the best/thickest FS High Mileage oils I found, Quaker State High Mileage FS is a bargain price. Castrol Edge High Mileage is also a bargain.
Then consider Quaker State UP FS. It's not a High Mileage oil. It's an extended OCI oil. Quaker State UP FS is thicker than all the High Mileage FS oils I mentioned. Quaker State UP FS is the thickest (per grade) FS (non Euro) oil that I know of. It's KV100 viscosity is right up where an oil cSt should/would be without EPA meddling. Hopefully it stays that way.

I just tried to download data sheet for Mobil 1 High Mileage 10w30. The link is broken. I downloaded the Mobil 1 High Mileage 5w30 data sheet 2 weeks ago, but now that link is broken too (as well as other grades data sheets links).
QS isn't the only oil company with website management problems. Mobil's website is having same issue, at least with all Mobil 1 High Mileage viscosities.
I didn't check the rest of M1 website.

There are 4 Castrol GTX engine oils in the USA. The The Castrol GTX Full Synthetic is the top GTX oil in the USA. It is not a synthetic blend. It is their 10,000 oci Full Synthetic oil, this is according to Castrol USA. Next up are the black bottles, there are three versions of that Edge oil, then the last is Their Gold Bottle Extended Performance oil. This information is according to Castrol USA Thursday, 2 days ago. Maybe they are lying to me and the entire world, but there is nothing on the bottle I have or on their website about this particular silver bottle Castrol being a synthetic blend. According to Castrol it is a "Full Synthetic" oil. It is their 10,000 mile Full Synthetic GTX.

I think you're correct. I thought GTX is blend. Maybe I just assumed that after seeing cold temp flow tests in which GTX was one of the oils tested. I was wrong with regard to at least some grades being blend. Maybe I was wrong about all grades of GTX. I'm not sure.
What I am sure of is that in cold oil flow tests I've seen, GTX did not flow well compared to other brands. In fact, it was dead last. Edge is a better oil. I could be happy using Edge.
I am not saying it is the greatest full synthetic there is out there, as a matter of fact it is the bottom of the barrel of the Castrol full synthetic oils they sell here in the US. All I am saying is, for a 0w-20, not 0w-30, but 0w-20, it has a decent vis at 100c of 9.0. For a cheap full synthetic 0w-20, that is thicker than many other 0w-20 oils out there. I didn't say it would flow, I said it was a little thicker than some of the other full synthetics. I hope we have this figured out. Believe me, I know it is not an Amsoil, Redline, Castrol Extended Performance or a Mobil 1 Extended Performance. For a 10,000-mile rated cheaper synthetic oil, it is a pretty thick 0w-20, if that is what you are looking for.
