Only one approval to run in all of your vehicles - which one?

[Bailes1992]

My go-to is a Porsche A40 approved oil coupled with ACEA C3 to ensure emmisisons equiptment compatibility.

D1G2 for me. Not that either of my Ford vehicles actually requires it, but the Ford specifications are harder to find and match up.

And I tend to use Kirkland or Supertech unless Pennzoil is on sale for less.

Which oils have both of those?

Which oils have both of those?

Motul 5w40 X-Clean 8100
Valvoline 5w40 Synpower MST C3
Havoline 5w40 Ultra S

To name a few. I used to religiously use Fuchs Titan GT1 XTL 5w40 which had a ton of approvals including A40 and was specified as being C3 but it seems to have lost a lot of the approvals. I don't know if they've got more stringent or the formula changed.

Does C40 supercede A40?

I know M1 X3 ESP 0W-40 has C3 and C40.

Thanks but how odd, at least to me. That Valvoline product no longer claims “suitability” with Porsche A40, and doesn’t appear in the Porsche approved oil list. A40 doesn’t permit a 30-grade anyway (only 40 or 50) so I doubt it ever had actual approval. The Havoline product does not have Porsche approval so that’s only what amounts to an incorrect recommendation.

As for the Motul product I also do not see where Motul claims Porsche A40 approval? The 8100 X-cess poduct does however (but isn’t ACEA C3), but not the X-Clean. Unless I’m missing something.

A40 does not have a minimum enforced TBN like A3/B4 and 229.5

you can make a c3 oil that’s also A40

 

[kschachn]

Does C40 supercede A40?

No they are still independent approvals. It’s probably possible that a C40 oil could meet the requirements for A40 but not the other way around. So you wouldn’t list both on the same oil.

TBN isn’t the distinguishing factor between the two approvals.

German Aral High Tronic 5W-40 used to have A40 and 229.51 (so a C3). Think they still have those approvals. Should have LL-04 and dexos2 too. Cheap in Europe!

I think they meant SAPS level.

I too have noticed a few Porsche A40 mid-SAPS oils, as well as the more common high-SAPS.

To me BMW LL-04 and VW 504/507 (= Porsche C30 I believe) are the true low-SAPS Euro oils.

But just from looking around, I never bothered to chase it up or study it.

Yeah, I've seen those two together too.
