Amsoil EFO 0w40 Euro Oil

[OVERKILL]

Isnt mobil fs 0w40 known to shear out of grade quicker? recall reading that somewhere. I havent seen HPL oil around canada or at least in Alberta where Im at.

Not any more than any other OTS Euro 0W-40, there's a stay in grade requirement they all have to meet.

The AMSOIL product is also an excellent choice I suspect, though I haven't used it personally. AMSOIL did have formal approvals for a while on their Euro oils, but it didn't appear to help uptake, so they stopped doing it.

You have to order HPL from the US (unless you drive to the US periodically) and shipping is a killer. I've been lucky that I have a buddy (@Rand) who tends to come up here most summers and he's brought it with him, though I've had to pay shipping the odd time when that arrangement didn't line up.

Being where you live in Ontario and use Supercar 0w40, , I suspect you have that SRT garage-kept and might even own an engine heater. Perhaps consider starting a thread someday on recommendations for such.
Happy Holidays ahead and your contributions here are over-the-top enormous.

Amusingly, it's not kept in the garage, because that's where the ATV's, dirt bikes, ladder and other crap is piled, lol. Yes, it has a block heater (most vehicles sold in Canada do), but I've never used it.

You'll notice 3 of our 6 vehicles use the edge 0w40, now in SP flavour. While it seems to be a bit different it is still 25-50%PAO and meets all the previous certifications...along with LL-01. Rather than look for a problem that isn't really one, I will continue to use the SP version. From the April 2024 data/SDS sheets:

Rowe Hitech synth RS 0w40 is highly regarded in Europe. It’s vollsynthetisch and has a high HTHS at 4.0. There are a few vendors that sell it online in North America.

Think I will give the amsoil a shot. At the end of the day I'm sure any of those would work just fine.
That hpl looks like good stuff. Following the winter when I switch back to 5w40 going to give motul power 5w40 a go. On paper it looks like a great oil as well.

I'm sure Castrol sp is just fine. I suspect the drop in pour point indicates the pao dosage being closer to 25% rather than 50. Again I'm sure it's fine, however my car does really well on the SN version and being the amsoil is similar other than noack is slightly higher thought I give it a shot and enquire about it. Thx

If you're not concerned about SA levels and out of warranty I'd go with SS 0w40 over Euro 0w40. Lingenfelter is using Amsoil SS and Dominator in their top engine builds, not the Euro line. Euro would work fine too.

 

[edyvw]

You are overthinking this!
Castrol, Mobil1 or Amsoil, all will work fine, tuned or not tuned, unless alcohol is involved, then we have different conversation.
I ran Castrol and Mobil1 0W40 on track with excellent results. I ran M1 up to 300f temperature and 5k OCI. I know VW owners who ran both on track in GTI and R.
You will be fine.
Personally, in Canada I would run good 0W30 in winter.

I would never intentionally step-down from the spec level of phosphorous for a Euro application; never intentionally use an oil with below spec levels of AW additives.

I think the SS would outperform the Euro 0w40, but I'm just guessing. AW additives look higher in the SS across the board minus 45ppm of P. SS has more boron, moly and ester. Also 100% LSPI friendly. Lower Noack too (7.7% vs 9.9%).

Euro has a SA of .91. SS is FS.

Those descriptions are out to lunch.

The SS oil is your basic API-oriented additive package, it's not LL-01, A40, A3/B4, 502 00/505 00:

0W-40 (AZF): API SP, SN PLUS, SN…; Chrysler MS-A0921, MS-12633, MS-10725, MS-10850; Nissan GT-R; GM dexos R

The EFO is full-SAPS, it SHOULD have much higher than 747 phosphorous.

But apparently it doesn't, also based on our previous discussion:

Post in thread 'Amsoil 0w40 SS'

Oct 10, 2023

These guys have run the Euro 0w40FS, and the oil temps weren't much different than the Amsoil. The Amsoil does have a large amount of Boron, which I assume is some type of boron ester.

I wouldn't expect the oil temps to be different, the oils are similar in viscosity and I assume the car has an oil cooler.

Do we have a VOA for the AMSOIL? UOA shows 32ppm of Boron, the SP Mobil has 145ppm (SN had 320ppm), but that's a VOA, and Boron depletes with use. My HPL VOA was 75ppm for example, and UOA showed 50.

I wouldn't run it with those levels. ALL of the mainstream Euro oils have much higher levels. Here's HPL:

The moly, boron, ester and overall base oil blend is better with the SS than Euro. If you ask Amsoil's top tech people and racing partners, they use the SS over the Euro oils. It's also possible that the higher boron and moly/ester achieve better AW than the Euro which has less of everything and maybe a bit more ZDP.

I can't find a recently VOA of the Euro 0w40 to confirm though. I wonder why the Euro 0w40 VOA shows such low P/Zn?

To play it safe though the Euro is probably better for a European application. I'm thinking off label use here lol.

Right, but neither is formulated as a Full-SAPS Euro oil is my point. The SS is clearly not targeted at that market, and the Euro 0W-40 isn't full SAPS, even though it claims to be, which would cause me to avoid it.

Most full-SAPS Euro oils target 900-1,000ppm phosphorous. Mobil 1 FS 0W-40 is 930ppm.

makes sense.

I haven't seen any other VOA's for the Euro 0w40. I wish I knew more about it.

I'd likely go with HPL Euro over Amsoil. I don't know...just seems Amsoil's Euro oils are OK, but nothing exceptional. But I'm going by what I see on paper which we know doesn't always tell the whole story.

OP is going under 4000 mi OCI, the Euro 0W-40 will be fine, especially way up north.

Agreed I'm sure all would be fine. Having used Castrol 0w40 sn for a while now it worked great in my car. Amsoil looked comparable hence the post. Just trying to stick with something that is similar too what has been working for me. But as you mention I'm sure all would work equally as well. I also do early oci's at 6000km/3750mi. Its short and I know the oil can run longer but for the cost, I do the changes myself cheap insurance for me.

I have two uoa's that show zn between 900-1000 (closer to 1000) and ph between 800-900. If I understand the comments you would avoid amsoil euro based on the additive pack and not being full saps?

Yes, the traditional full-SAPS additive package typically has between 900-1,000ppm of phosphorous (the main anti-wear component), because it is not constrained by the API in the xW-40 grades (which is why full-SAPS Euro 0W-30/5W-30 oils are only API SL).

Phosphorous is restricted by the API in xW-30 and below for "catalyst protection", with 800ppm being the cap. This was introduced in API SM, where the API neutered the typical PCMO grades (xW-20/xW-30) to protect emissions equipment in the event that an engine burned enough oil for that to be a problem.

I would trust those over the singular outside the USA/Canada VOA/UOA's. Plus 50ppm in Zn/P simply will make no difference. Look at the Mo and B levels for example.

Interesting. I viewed some motul xcess gen2 uoa's and have seen both ph and zn below 900. It varies but of the only two amsoil 0w40 uoa's I have (from 2023) the zn and ph were comparable for sure. If anything the zn in the amsoil was higher. This is after xxkms driven in a different vehicle but comparable none the less.
