It is no coincidence that Amsoil, and PT Barnum-Banks are partnered up.I got around to reading this Amsoil publication. Amsoil claims the following:
"It’s worth noting, however, that many GTL catalysts and processes generate highly paraffinic (waxy) base oils with undesirable characteristics. In fact, residual byproducts of the Fischer-Tropsch/GTL process can significantly affect the oil’s pour point and volatility."
Seems like a very misleading and highly speculative statement, using words like "many" and "can". i.e. - Amsoil is not speaking specifically of the GTL process Shell uses to manufacture their synthetic oil - they likely do not know! So they toss out doubting statements like this from a weasely politician.
Amsoil did not publish a NOACK test for PUP, and neither does SOPUS. Until or unless Amsoil did, I wouldn't rely on any of their half-truth marketing blather. They published PP.
SOPUS (Shell Oil Products U.S.) manufactures their own GTL base oil from what I can discern (see below). I don't know where, but they source their LNG (Liquified Natural Gas) from their massive terminal in Qatar, UAE.

The spotlight is no longer on a technology that enjoyed much hype but did not seem to deliver. But the time maybe right to turn the power on again.www.lubesngreases.com
Amsoil has stated (at least in a Gale Banks Video) they do not manufacture their own synthetic base oil - they buy it from someone else via rail tank car. They showed this in the video, saying they inspect the oil, test it for acceptance, and have rejected loads that didn't meet their specs. Amsoil is just another lubricant blender - they are not an integrated manufacturer.
This said, they are casting stones of doubt at someone else, claiming their quality may be lesser WITHOUT any test evidence. Shady, IMO.

No it isnt. Their "full synthetic" is not GtL and it has the same Pour Point as PUP. In the perfect world we would have some uoa's that compare the two in the same engines, but all we can do is guess.

I am pretty sure Lucas is about to join up and make a super dope partnership that will in fact blow your doors off.

Is there much difference between Pennzoil platinum and Pennzoil Ultimate platinum both 5-30 weights with lubeguard added?

Higher detergency with PUP and I encourage you to look up uoa's. I do believe for whatever reason PUP has better uoa's, but I havent really checked for years. When we had the free Pennzoil here the "official" word from pennzoil was the only difference was the detergency, IE calcium level.

I don't own a 5.7 Hemi but I do follow this thread. I enjoy the reading and like to remain informed. It certainly seems like Shell plc is the major player in GTL lubricating oils. As we all know they market several brands of oil. I was using Rotella gas truck in my Pentastar and was happy with it. It is no longer available. My next to last oil change I combined what I had remaining of RGT ( 3 quarts ) with three quarts of Quaker State Full synthetic. VOA of RGT and QSFS appeared to me to be quite similar and this did in fact have an influence on my decision to mix them together. I see Penzoil mentioned here but don't recall seeing QSFS in any discussions. ( perhaps it has been mentioned and I just don't remember ) Moly on my last UOA with the RTG / QSFS combination was over 200.
I will most likely be using QSFS down the road.
I am curious if anyone here has considered or is using QSFS and why or why not?
Considering that Penzoil seems well accepted, what might the feelings be with the QSFS? Same GTL technology for both from the same source.

Shell is Pennzoil and Quaker State. They bought both brands some time ago. All have been rated high quality.

@Burla - check my memory, I recall reading Amsoil Signature Series is Group IV PAO, and the lesser series are Group III catalytic-cracked crude?
Methane (natural gas) manufactured into oil via the Fischer-Tropsch process has been appropriately called a Group III+. It can't be called a Group IV because it's not a direct construction of linear molecules from a double-bonded molecule (ethylene). Methane has to be deconstructed into an interstitial gas (syngas), then constructed into linear molecules.
For whatever reason, the Germans derived methane from coal to make syn fuel and lubes - I supposed they had no access to crude oil and the ethylene gas that comes with it.
Anyway, GTL is higher saturated than Group III, so it is a Group III+. I don't recall if GTL reaches the saturation min. % of Group IV.
*Saturation means the % of the carbon molecule chain that has only a single-bond. Double bonds are reactive at far lower temperature and shear than single bonds.

I forgot the minutia because my good friend Brian takes up the slack. I think we coined that term a long time ago GtL is group 3.5, but you said it much more eloquently. Funny Bobs call saturated oils undesirable, at least that was the constant tyraids back in the day.

For a group of guys that like to get into subatomic particle physics, I don't get why BITOG can't comprehend simple application criteria.
Maybe the spin direction of the top quark particle is fascinating, IDK.

their leader goes by the name pimweasal, lol. What do you expect?
it's not a serious place.
LSPI info. From his last point, is it safe to infer that low tension rings contribute to the issue?

Question- PCV when operating takes blow by and re-burns it, what is blowby? Engine blow-by is compressed air and fuel in the cylinder combustion chamber going through the piston rings into the crankcase ventilation... HUH? So there are rams w/o a changeable pvc and many others where changing the pcv is a dealer job costing a thousand or better due to engine position. But, is that all we can do? What about running redline si-1 or other concentrated PEA/Techron though the gas since the fuel is the number one thing in engine blowby? Would this prevent pcv clogging with longterm use? Posted a while ago the level of detergency in gas is minuscule, but adding a concentrated PEA additive such as si-1 boost that significantly. I'm not sure you have a choice, but perhaps there is this option.
My SUV pcv you are taking off stuff if you want to get to it, I'm just gonna risk it but I will at least try this strategy and perhaps I will double my 100k worry free miles I just accomplished, time will tell. have a pentatsar or 6'4 w/o a pcv, what's the plan?

Another way to prevent and minimize blowby that is often overlooked is to use a high detergent oil that keeps the oil control rings clean. This in turn keeps the compression rings free to move and expand to keep compression in the combustion chamber.
For the wife's Jeep with the Pentastar, I'll probably just change it when I do spark plugs on it. I think we're going to buy out her lease, the new ones are looking to be around $600/mo for a LEASE
. I'll know when we get closer to August 2023 when it's due, they always call a few months ahead and all of a sudden have much better deals...

Yes.. complete combustion and low volatility oil are key to reducing unburned hydrocarbons in the pcv.

Dare we get into octane rating again, oh no way???
Another reason to use 89+ octane to prevent pcv clogs? Using a lower octane then the tuning of the truck might create more blowby?
