Castrol vs Valvoline

He's trolling BITOG.
The GTX full syn has a higher vis at 100c than the Edge products. That is what I am after. I will probably only go 5000 or 6 months oci also.
The GTX synthetic is a little thicker than their Edge oils. That is what I am looking for in a 0w-20 weight.
People should also remember that typical values from a PDS are just that, typical. They may or may not reflect any particular lot nor what is on the shelf. Trying to fine-tune a grade by selecting one that is a little thicker is not guaranteed. The only way to get a guaranteed thicker oil is to move up a grade.
Some blenders don't even report "typical" values but are grade or license limits instead.

Well, I just want to try it. I have Schaeffer's 0w-16 in it now. I could use that but it is a pain for me to get from my local distributor. It is a 70-mile round trip to get the Schaeffer oil. The Castrol GTX synthetic 0w-20 I sent in just hit the Polaris lab today. We will see what that says in a few days. Do you know anything about Idemitsu IFG 3 0w-20? I know it is from Japan and manufactured at their plant here in Indiana. Are they just another oil, or is there something special about their oil? Just asking.
Back in the day when at work we had some lubrication engineers come through on a plant tour.I was at the lathe and they asked me what I was doing and I explained my process.This was when conventional was a lot cheaper than synthetic oil.I asked them in your professional opinion what's the best conventional oil out there and they all agreed on Valvoline.Then one of them gave me a Castrol Lubricants sticker and I put it on the inside lid of my toolbox. LOL! Like the dude on project farm always says there a lot of synthetic oils out there and they all do a good job!

Castrol purely for sentimental value .....it may be sold off soon
Valvoline is owned by the Saudi government through Aramco. Saudi Arabia is a religious dictatorship that does nasty things
Castrol is owned by British Petroleum a shareholder owned company headquartered in a free country
And Britain is free ?? Not from what has been going on there in the past few years. ANYWAY . . . Castrol is supposedly being eyed by Shell, another British company (Royal Dutch Shell moved their HQ from Holland to Britain a few years back). Would make sense for Shell.
I normally buy products based on quality, not politics…
I’d go further and say based off objectivity and logic.

CasterOil always cleared me out good.
So I trust it'll do the same for your cars.

Castrol always seemed to keep my engines internally clean during the 70s, 80s, 90s and 2000's
I was always specifically impressed with that about Castrol.
VRP seems to be the next level for cleaning.
That said, I recently decided to try Delo XSP 15w-40 in one of my 1999 minivans.
Seems to have bumped the oil pressure up a bit when moving, but it seems slightly lower hot at idle (not good).
So post#47 seems to make sense.

Castrol Edge (not GTX) and Valvoline EP are both excellent IMO. The Valvoline is thicker (higher viscosity) if comparing same grade oils.
For example 5w30 Edge is thinner than 5w30 V EP. 10w30 Edge is slightly thicker than 5w30 V EP. I think this trend also trend applies to other grades as well.
You can't got wrong with Edge or Valvoline EP. Choose either. They're among my favorites. When not on sale, Edge costs less than V EP. So I'd choose Edge between those 2. You won't always be able to find these oils on sale.
Another excellent choice that costs the least is Quaker State Ultimate Protection Full Synthetic at Walmart. I personally think it's (arguably) the best of the 3. I intend to use this oil in future.
My other favorite is Shell Rotella Multi Vehicle.
QSUPFS & Rotella are thicker per grade than the others mentioned.
Don't buy anything American or British either.

I don't like the Castrol GTX family.
I like the Castrol Edge family.
I like the Valvoline family in general, but especially their Maxlife & EP familiies.
I like the Quaker State family.
I like the Shell Rotella Multi Vehicle family.
That said, all of this thread is splitting irrelevant hairs for a 5K or 7.5K OCI. Probably even a 10K OCI. Any brand of certified oil is more than good enough for 5K to 7.5K OCI.
Both oils OP asked about are excellent for 10K.
If you want to discuss 15K or 20K OCI, then don't use V EP. Castrol Edge claims to be good for 20K. It might really be good for 20K. I don't know. I'm confident Edge is more than good enough for 15K OCI (with a good ext OCI filter, such as NAPA Gold). Likewise with QSUPFS & Rotella MV.
Even for severe duty, 10K OCI would be no problem for Edge, QSUPFS, or Rotella MV.
