$92 otherwise

Edit: canceled my order. Looks like trash. I’ll pay a little more for piece of mind. Thanks everyone

not sure how much I trust that brand, but significantly cheaper than even Supertech...

I'd buy their 25w-60

That is the one that sheared 30% when tested.

I’ve seen some talk about that but haven’t been able to find the original post. Was the testing an extreme test? Pushing lubricants to levels that wouldn’t been seen in the real world? Any link? Thanks.

Thread 'Mega 75w-90 testing thread!'

Jan 15, 2024

@ford250 @SNWMBL @Impatient and maybe more (sorry, it’s been awhile!) contributed samples for this test.

We’ve imported the other 75w90 tests from my other thread here, and also add these 75w90s:
Shell Spirax
Subaru HP
Ultra Plus (cool clear bottle!)
AC Delco
Valvoline Synpower
Ravenol VSG
HPL non-CC Diff Life

Somehow, I misplaced the Motul Motylgear so that didn’t get submitted. Apologies. Lab also included foaming results, but I have not read the ASTM method yet to determine the pass/fail criteria. Looks like vsl= visual, and tr= trace. Other than that, here’s...

at least they come in clear bottles

Correct. It’s more akin to olive oil mixed with the worst VII ever than it is to gear oil…

I would 100% use Supertech instead. They make a GL-4 version and I made the mistake of using it in the transmission of my manual xB for a couple of weeks. The noise and terrible shift feel convinced me to dump it ASAP and replace it with Motul 300.

 

[Rand]

Ah yes, my initial distrust of the brand and deal were not mistaken.
30% viscosity loss.

 

[D60]

I'm the king of basic, inexpensive fluids and even I am unwilling to risk Ultra 1. It's just sketchy.

 

[pda1122]

I dont understand how they donate to PQIA if they are no good. They meet ratings like gl4, just sounds like they’re really inconsistent.

 

[D60]

I'd run their ATF in a part-time t-case or maybe even an old school TH350, C6 etc. Would be great for my leaking 2-post Bendpak

But gear oil....eh, makes me nervous
