Personally I'd still like to get a handle on what the eff the junk is we have found the bottom of new HPGO bottles. Precipitate drop out? Junk from manufacture that wasn't filtered out? Unicorn dandruff?

Yeah that's what I figured I know they have some special shipping, wouldn't make it worth getting that oil.


I thought I said something about that's as well regarding that stuff floating at the bottom of the containers, i thought it could be additives that just fell to the bottom. I shook the bottles and when it was emptied I barley saw any in there.

Has anyone had success with hpgo? My tranny fluid needs to be replaced and I'm thinking of jumping the gun on this because of the price.

I'm close to 2k with it and my transmission seems to like it. That Amazon deal is legit I paid like 60 bucks for 5 quarts.

My DCCD is making noise in my 06 STI. Read another thread where someone posted this video of the exact same sound, and he fixed it by switching to Extra S. Now that Extra S is gone, is HPGO even a legit alternative?! I gotta fix this I can't deal with this sound.

Shouldn't you be using a limited slip fluid in the DCCD? I don't think hpgo or extra-s for that matter are limited slip.

Only the rear diff needs a different type of fluid, and only for early models of the STI.

Tough call, have my 30K service up, was going to go Motul 75w90 300 all around then considered Redline 75w90NS for tranny and Motul 300 for diff in my 6mt, however this HPGO is so cheap on amazon but I see there are two Subaru OEM PN of K0322AA093 which is $33.42 shipped for 4 quarts and then there is the OEM PN SOA427V1700 at $48 shipped, whats the diff, bottles look identical and are referred to as identical?

SOA427V1700 is Subaru of America (SoA) 75w-90 HP gear oil - EXTRA-S alternative made by Idemitsu, not identical to Extra-S, less metals maybe more non-metal additives.
K0323AA093 is the p/n for Subaru GO EXTRA-S 75w-90 although in a 20L pail, US dealers can't order this through SOA anymore, and it is highly unlikely being imported in other manners.

Default Schaeffers 75w-90 Supreme Gear Lube Synthetic Plus

I'm curious if anyone has switched over or knows if the Schaeffers 75w-90 gear oil is safe/good to use in the 2005 sti 6mt? I've just seen one amazon review so far on it, a guy used it on his 2012 WRX for his trans/gear oil. Thanks for any insight. If no one chimes in before my rear diff gasket comes in then I'll pull the trigger on it and let everyone know what I find out here our a new post. Thanks

1 year+ on the Motul 300 and it's still smooth. In all sorts of Michigan weather and with all sorts of driving. Including some pretty hard autocross launches and shifts.

For what it's worth, I've run the Extra-S through the last 3-4 years, 30k, and probably 30 autocross events. It's held up fine and from what I can visibly see from the front diff (4EATer here), it's not burn and looks fine.

However, with 30k on it, I was planning on swapping it out only to find it's discontinued. I will be sticking with Subaru's ATF for the tranny, but most likely going with Motul 300 for the front and rear diffs.

I actually prefer to stick with OEM fluids for the tranny, diffs, and coolant as Subaru usually knows what they're doing, but from what I've read here and other places, the new formula seems to have issues. Boggles my mind why they would swap to this. Extra-S was some great fluid and available through most performance shops with ease.

What is the issue with having gear oil up to the F line? Is it suppose to be kept between F and L?

I also must add that after doing a drain and fill with HPGO, my theory is that it must be thin or becomes thin at high temps, and in the mornings my shifting will be great for the most part but once I hop on the freeway and get things cookin', my 3rd to 4th gear shift gets a little sketchy and grinds almost everytime.

Everyone's experience and expectation with HPGO may vary.

My 5MT experience is similar to above. 100% fill HPGO worked fine for me right at the initial start. It did seem to be slightly improved over 100% fill ESGO in winter cold starts. I have a commute with lengthy highway routes which might not be the normal usage profile. Seems to me once heated up it starts to lose some of its mojo. Possibly it could be foaming like posed earlier in this thread (but I never confirmed that). I had run it a the Full mark with these observations. Then I slightly overfilled but the behavior did not change.
I later moved back to a regular 75W-90 GL-5 gear oil which returned a more normal behavior. So I'm sticking to that regular gear oil for the remainder of this 5MT's life.

That said HPGO will not be going into my 6MT. I'm not even interesting in trying it out. Motul 300 or Torco RTF will be replacing the final ESGO inside the 6MT.

I wish Subaru would resume ESGO importing.

So after reading through vaious things of Subaru Extra S that is supposed to go in my 05 STi's tranny... the new Subaru 75-90 High Performance Gear oil is NOT a good choice for the manual tranny fluid?

Extra S is non existent anymore... I can't get a clear answer from the dealer that I ask. They all say This is what we have. But yet when asking about putting it in my tranny or rear diff they all say "this is what we carry now"...

I found this:

No one has determined it is NOT acceptable for the 5MT. Ultimately you will have to try it out for yourself....but I expect HPGO will likely work fine for your car.

What I can tell you is US Subaru dealers will NOT get the actual Extra-S ESGO anymore. SOA removed the means to order ESGO. Allowing ESGO in would compete with SOA's "alternative" offerings and cut into the profit margins built into HPGO.

Schaeffers tranny and gear oil are working wonderfully in my 2005 STI. Everything is super smooth and haven't noticed any grinding what so ever.
