Gulf ULE 5W-40 - Anyone have VOA or UOA or any details on chemical makeup?

[rocketthewhippet]

Hi,
First post. So if in the wrong area please delete and let me know where it needs to go.

I've got a Porsche 996.2 and many of the recommended oils on this forum (and others) are really only available in the USA. Driven DT40, Pennzoil Ultra P, Motul X-Cess Gen2 are just not available here. Redline is crazy $$$ and at small volume no idea how long sitting on the shelf slowly separating itself

I've got two preferred indie Porsche specialists and both use Gulf ULE. So I thought I'd see if I can get any info.

I appreciate any time anyone spends on responding.
Thank you

Well, it has Porsche's coveted A40 approval, which is good enough for me.

We have subforums for both UOAs and VOAs.
You can search them using the "search" function and selecting the appropriate forum for the search.

Also, I moved this thread to the proper forum.
Please pay attention to where you search and post; it will help us all in the long run.

Lots going on in your post there, you ask about a Gulf product and then divert into Red Line and Driven and Motul and....

What is the Porsche approval your vehicle requires? That has actual technical significance as opposed to a PDS or cheap spectrographic analysis of "chemical makeup".

Probably could make it clearer. Basically Driven, Motul, Pennzoil which are all A40 Porsche approved and highly regarded for the moly content and base oil, just isn't available in Australia. Redline is available but crazy $

I'm just after Gulf 5w-40 ULE components - does it have moly? is it group III or III+ .

Why am I chasing moly content? I could be lost in the weeds here but the bore of the 996 M96 engine is lokasil which is prone to bore scoring. Lots of chatter that moly can really help minimise this from occuring. Plenty of A40 oils that have 0 moly. I'm looking for one that does have moly and I can get here in Australia

No Molly.

Look for Porsche A40 with API SP.
Higher chance of having molly I think.

Shell Helix Ultra or Mobil 1 in 0W40 with API SP for example.

Again, what is the Porsche approval in the owner's manual? All that stuff about highly regarded moly content, base oil, crazy $, Gulf 5w-40 ULE components, weeds, bores, "lokasil", and chatter are secondary.

And no one here knows the chemical composition of that oil. A PDS or $30 spectrographic analysis of decomposed compounds is not a chemical composition. You go by the approvals the oil holds, or does not hold.

Porsche has some engines with scoring problems, his concern is somewhat legitimate.

Indeed he may be. But asking about the "chemical makeup" of that oil isn't going to go far, at least in my opinion. I struggle with the notion that one isolated element is the make-or-break on this or any engine.

Does it have Nikasil coated bores or is it an Alusil block? I can't tell from "lokasil". Either way there must be something wrong with the alloy or the application process since both are extremely hard surfaces.

Lake Speed Jr is a gun on this stuff. Everything I've mentioned he's recommended on his channel or this video I cannot get.

And plenty would have been using the 'A40' recomendation that ended up with scoring and a 50K bill

Nikasil used in Turbo / GT engines otherwise known as Metzger engines. . Ausil used in air cooled.

Porsche moved to Lokasil for the 996 (first water cooled) flat six in 1998. We're 25 years down the road. The cylinder liners haven't changed but oil technology and understanding has... I would think

Lake Speed Jr, in one of his many videos, talks about moly making a difference in protecting the bore. Hence the hunt.

I guess I'm going to have to get a sample analysed. Rather avoid if the information was already available.

API SP with A40 or maybe even C40 is the answer, or atleast a good starting point.
Do UOA if you are unsure.

And yet we still don't know what your owner's manual lists for an approval.

If you believe that video then I'd do exactly what they say.
