Amsoil to add 0w40 euro formula

I would rather put my money on approved oil and car's original warranty, but everyone has the right to deal with its money the way it likes.

Would that be good enough for you?

Still a 5W30 with a HTHS of 3.6 looks better to me than
a 0W40 with a HTHS of 3.7, unless I'm out in -40 weather.

The long list of 5W40s, suggest that this
is the preferred grade for manufactures seeking engine
protection instead of fuel economy.


Yet the official AMG oil is a 0w40! Made in Belgium apparently.

Apparently a lot of good things are made in Belgium.

I couldn't open the pds on the AMG oil to see the specs,
but I would almost bet money the HTSH is higher than
3.7.

Even the down and out Pet-Can 0W40 Duron has >4.1< HTHS.

There is a bit of bad history with the 0W40s in
North America.

Like falling out of grade for instance.

The pds link went to a totally unrelated (but nevertheless interesting) document. No HTHSv I am afraid.

I have a theory about why AMG and Mobil 1 and now Castrol as well offer a 0w40 when they don't offer a 5w40 as widely in particular in North America.

As to there being some kind of problem with a 0w40, don't forget that the all mighty M1 0w40 is factory fill on a lot of these vehicles.
 
I know, and I used 0W40 for years in my 04 C240.
I had to buy it at auto parts stores and pay through the nose.
If and when I could find it.

Previous to that, Esso (Imperial Oil) introduced XD-3 0W40
with a KV100 of 15.7.

We lost our Esso branded products when Imperial bought
Exxon/Mobil. Mobil brands are now available at
bulk Esso distributors.

For the longest time, all we could get was the reasonably
priced XD-3 and the over priced M1 0w40.

A few years later Pet-Can rolled a very cost effective 0W40 Duron,
at half the price I was paying for M1 0W40.

I bought a 20L pail and tried it out in the Benz,
oci 25% past the OLM at around 21,000Km.

The UOA looked good, except for the 5% fuel in the oil.

Esso, at this point had not re-branded the XD-3 to a Mobil label
that I knew of, so Duron became my 0W40 go to oil.

I learned that the introduction of 0W40 was not all
roses for other brands, many experiencing major thinning
out of grade.

Because of that history, when a new 0w40 hits the
market from North America, the HTHS is 10w30ish,
the KV100 at 13.3 and there is no license or
certifications.... I'll pass thank you.
 
And over here, I've got a several year stash of various approved Euro oils, mainly because I managed to take advantage of deals almost as good as the best deals on API oils.

And when our gas quality improves, we may be able to run 2 year oci's without blinking.

Even in Europe. For example years ago I read complaints that the BMW branded 0w40 LL04 was suspected to increase oil consumption. I wonder if some new VII was developed making these wide spread oils more robust in terms of maintaining grade.

Dang, I just stocked up on two oil changes worth of the Castrol Edge 0w40. The price of the Amsoil EFO seems substantially higher than Edge, and M1 0w40 line when you get the Jug deals.

What about the quality of EFO being twice as goood? I'm not convinced that it is, after coming here.
I'm still glad that Amsoil is offering EFO now, but I feel it's a little late.

Sorry,I was under impression this oil meets all current full SAPS approvals for European engines sold in NA. If not then why choosing this over Castrol or M1?

That is the point in this discussion.

I don't think an oil going out of grade is a "bad history". There are many oils that do including historically many 5w-30's. And this isn't always due to the visc spread but also fuel dilution. A 5w-40 in a 6.0L PSD Ford/VT365, despite being much heavier than your typical 0w-40 in both the HTHS and KV department is even less likely to stay in grade. What negative effects on longevity do you think this has? The answer appears to be none.
 
I did some checking and the extreme characteristics of the EFO make it look like very good base stock quality.

I feel the EFM would be more like EDGE and M1 in material.

I've been a little off topic, but thanks to Pablo, I can see the advantages.
 
EFO probably is not twice better but AZF 0W-40 is for sure far better than Edge or M1 because of Amsoil own top quality additive pack like all Signature Series oils have - I would use AZF in twin turbo engines like AMG or BMW instead of OEM 0W-30 / 5W-30.
EFO will probably be listed soon as approved exactly the same like 5W-40 EFM so no problem with using it in new cars under warranty - this is how EFM and EFO oils are supposed to be sold I assume.
 
That, or just blend two already existing products together and call it your own.
Since there are no tests to pass, the evaporation loses will keep the grade in check as it shears.
 
If I didn't just buy 2 cases of EFM I would try the new EFO. However, $5.40/qt is much better sounding than $6.87. And so far I've noticed my S4 (has an oil temp guage whereas my A4 doesn't) has seen lower oil temps compared to AFL. Not much lower but maybe 25 degrees lower during normal driving.
