Delo 400 15w-40 ACEA Specs A3/B4

[MarkIC]

Hi guys,
I'd like to use Delo 400 in my mitsuibishi 2010 NT montero turbo diesel (in Australia).

This is a 4M41 3.2 litre common rail turbo diesel.

Delo gets great feedback but does not have the ACEA A3/B3 or B4 spec that is listed by Mitsuibishi.

Would Delo not meet this B4 requirement or has it just not been tested for it. If it couldnt meet the B4 test requirements in what area would it fail the A3/B4 requirements??

Thanks in advance for any light others can help with on this
Cheers Mark

With A3/B3 A3/B4 being gasoline specifications, it doesn't surprise me that Delo (and other HDEOs) don't show it, even if they have the HTHS, TBN, and so forth. The HDEOs I've seen tend to show the ACEA E specifications only.

Hi thanks for the information although I thought the a3/b4 was both a gasoline and pertol rating.

A3 is for the petrol & B4 is the Diesel with these clasification types combined together after 2004 to become the A3/B4 classification.

ACEA list the a3/b4 for quote

"A3/B4 Stable, stay-in-grade oil intended for use in high performance gasoline and direct injection diesel engines"

So I guess my question on why dello E7 oil wouldnt meet the b4 category is still out.

We do have some oils down under that comply with both its just that Delo 400 is such a good price and gets a good wrap I thought it would be a good cost effective choice

Cheers Mark

No problem, I knew what you meant.

In any case, with these HDEOs, I would suspect the oil companies are more interested in meeting and listing the relevant ACEA E specifications. Personally, I've never seen the E specifications in conjunction with A/B specifications on any HDEOs, and that includes various Delo, Rotella, and Delvac varieties; they all have E specifications only, at least for the ones I've seen. Are they even allowed to claim A/B in conjunction with E? I'd have to check deeper, but perhaps there's a prohibition against claiming them both.

I do know that some HDEOs are slightly low on TBN for an A3/B4 rating, but some aren't low. So, I'm not totally sure.

There's no prohibition from claiming A/B with E specs, but they tend not to be combined as it is a load of work and cost to get these specs and the products would have to be over-engineered to achieve both, hence making them costly and unattractive to the HD users.

As said above, A is gasoline and B is diesel (light duty) and they must ALWAYS be combined on a product. E specs are for HD diesel.

Thanks, Weasley. I just did some checking before I read your reply, and that matches exactly what I came across. As you note, the A and B specs are combined on the product, and the E is for HD diesel.

I did come across a few examples where there were A/B and E specifications on a lube. Penrite listed a few, for example. It's just something we don't come across a lot in North America, where HDEOs will stick with the ACEA E specification. As you indicate, it wouldn't be very cost effective to toss an A3/B4 on a lot of HDEOs. That's particularly true in North America, where hardly anyone actually looks for an A3/B4 lube specifically. Anyone requiring such a lube here is actually looking for the OEM specifications (VW, Benz, and so forth), so tossing an A3/B3 A3/B4 on an HDEO (without the European proprietary specifications) isn't going to get them a lot more sales.

Thanks again for helping clear this up!
