75w-80 GL-5 / Unicorn tears

[RamFan]

Alright folks, time to change the front diff fluid in the Giulia. After striking out at two dealers I’m turning to BITOG.

Does anyone have a source for a full synthetic, 75w-80 GL-5 gear oil? Triax is the only one I’ve found, but it’s Triax…

 

[twX]

Motul Motylgear and Fuchs Titan Sintofluid. I think they're only semi-synthetic though. Using a 75W-85 would give you some more options.

 

[slacktide_bitog]

Just use the 75w90

Perhaps this Febi 75w80 GL5 might work

 

[martinq]

Use 75w90 or check Amsoil & Red Line for 75w85.

Q. Is fuel efficiency of utmost importance to you?

 

[RamFan]

Using a 75W-85 would give you some more options.

I’m likely to do that if I can’t find what I’m looking for. I’ve got Ravenol 75w-85 going in the rear already.

This could do the trick, thank you!

I put Triax 75W80 GL-4 in my wife's 2015 Audi A4 quattro that has a 6 speed manual. It works. I don't use their engine oil however and don't like their over the top marketing. If you look at their SDS it doesn't state containing PAO and esters.

Also to note I highly suspect they produce the made in USA VAQ limited slip fluid exclusive to a few VW GTI's and GLI's. The bottle and cut & printed bottle sticker is a copy of what Triax uses, not Mobil or Castrol and I doubt the majors wanted to bottle a measly who knows, a 1000 bottles a year.

its gl-4/gl-5 dual rated.

or you could just not care about .1mpg and use a 75w85 tons of good options there.. such as amsoil SVG.

Hard pass. There’s not one single piece of verifiable information in their claims… how does one measure “superb” foaming resistance? And so on down the whole list of “benefits”.

What exactly is soft mental synchro damage?

 

[SubieRubyRoo]

And I’d love to see the “PAO-Ester” content when this is the SDS:

Which that wording sounds suspiciously similar to this thread:

Thread 'What is "Highly refined mineral oil (C15 - C50)"'

Dec 2, 2010

Hi all. I was reading the MSDS for Chevron and Havoline and I saw this line:

Highly refined mineral oil (C15 - C50) 75 - 95 %weight

What is "Highly refined mineral oil (C15 - C50)"? Is it Group III oil?

Here is the link:

Thanks.

I think 75w-85 would work so maybe check for a local amsoil dealer or just order the 75w-80

 

[JavierH19]

Maybe a local nissan dealer sells this stuff? Don't know about the clutch in the front diff though.

 

[The Critic]

HPL sells some. Reach out to them.

Wow, that intern really didn't pass their high school English classes I guess.

- foaming resistance is classified as "superb"
- shear stability gets a rating of "extreme"
- corrosion protection gets a comma before "and"
- "prevents slippage" and "facilitate(s) smooth shifting"
- seal compatibility is "with natural or synthetic"
- Compatible with "&manual" transmissions
- low sulfur prevents "mental synchro" is a perfect closer

 

[Marcozi]

Just replace it with Redline.

Just replace it with Redline.

redline doesnt make a 75w80 gl-5...

 

[Spedestrian]

HPL has a 75w-80.

I used their 75w-85 in the front and rear diffs of my bmw.

I read your criticism and assumed we were talking about Amsoil claims. I was cringing knowing the pushback that was coming.

Then I realized it was Triax, so it's okay.
