Are there any tests more challenging in your opinion?

No one shares test protocol or details. Which tests have you seen? For CEC you have to be part of the group and pay to see the test protocols. Porsche are one of a few OEMs who own the test and control the oils that run in it, others allow external test houses to run the tests on their behalf

VW 504 507 type testing and BMWs new N20 test.

VW, Mercedes... they're all pretty well documented in the Afton manual.

are there any oil that meets LL-01 and MB specs that don't meet A40? Just curious....Most Euro oil available to me over the counter usually meets all three German specs.

Is A40 more stringent than other Euro specs?

Well, yes. All the Xw-30 oils for example, since Porsche A40 does not allow Xw-30 grades.

 

[Leonardo629]

right, forgot about that

I guess the conclusion remains the same, you really can't go wrong with either M1 0W40 or Castrol 0W40 if your car calls for 40wt oil.

Xw-30 oils here are mostly for DPF equiped vehicles....and have LL-04 specification (BMW's for DPF...)

Maybe check the Mobil Oil or Shell website for Slovenia for recommended oils in a gasoline BMW engine. I think as long as the gasoline fuel used is low sulfur like western Europe, (not the U.S. and some other places with high sulfur), then LL-04 can be used very well in gas engines.

From an Opie Oils document about BMW specs:
" LL-04 oils must not be used in BMW spark-ignition engines in
countries outside Europe (EU plus Switzerland, Norway and Liechtenstein)."

I bet Porsche doesn't publish the test criteria so rouge oil companies can't claim they meet or exceed the specs, which helps the companies that get the approval.

 

[Quattro Pete]

It still won't stop rogue oil companies from claiming that their oil is recommended for Porsche A40 applications.

That is correct....you can use LL-04 (DPF) oil in gasoline BMW.....as u mentioned where gasoline has low sulfur content ( due the lack of abillity of DPFs oils to absorb acids)

LL-01 and LL-04 can be "interchangable" in GASOLINE engines.....

Did the test criteria change when they moved to 504 from 503.01, or was it just the added requirement for the oil to be low saps? It seems to me the later would be a better oil to use in the USA, which would explain GC/BC 0w-30 still being the older SL formulation. Thanks!
