Thoughts on GTL base stock synthetics?

[OVERKILL]

Absolutely do not hate PAO. For every good thing there is a balance of negative. I just have not heard of them here. I am just uneducated and want to learn. When I read about something I want to talk about it. You guys are a great source of discussion. PAO by itself does not do the magic IMO but neither does any base oil. Several oil blenders use PAO. When the OP asks a question I start to research. I found that GTL can be on par with PAO on VI also that GTL is also non-polar. And while the hydrocracking process for GTL puts it in the group III it is different. Plenty of benefits are added to PAO with a balance of POE and the additive package. All stuff I picked up from the OP.

Well, those things have all been discussed extensively in older threads.

And yes, GTL is still a Group III (hydrocracked) base oil. The difference is of course the feedstock, which results in base oils with fewer impurities and higher VI's than more traditional feedstocks. I think @RDY4WAR might have posted more details on that process a while back, but I'm not going to get into it in this thread.

Can you link that marketing? I really don’t buy into anything but demonstrated performance through approvals.

It's Called Mobil 1 Annual Protection oil and they recommend using their Mobil 1 EP oil filter to meet it.

Annual protection was discontinued two years ago, and Extended Performance now makes the claims that Annual Protection did.

It might, but once again those aren’t requirements listed in Annex E for base stock interchange. You talk about people focusing on the wrong things on here yet you’re doing it with measurement properties that aren’t related to the Group designation. I’d counter that people focus too much on Noack, flash point and pour point which are relatively unimportant to performance in use.

The Annex E are guideline to safeguard PR departments against potential litigations.

You are correct that it's wrong to focus on the data, as the producers probably distort the figures to achieve desired product perceptions.

No it is inherently technical. Have you even read Annex E? It’s designed to allow base stock interchange without requiring recertification for an API license. You really have no idea what you’re talking about.

PAO has higher oxidation resistance and better cold temperature performance, so it's better at both ends of the extremes range. For your typical application? Neither of those things will likely be relevant, though the oxidation resistance does help with extended drain capability, which may be some of the reason we see it in M1 EP oils.

I guess my Toyota minivan won't feel the difference lol. I am taking the cheap GTL
