That might be true, but one still could come across some inappropriate lubes. It might take some doing, though. After all, any 15w-40 HDEO you or I find on the shelves is very likely to be dual rated. I'm still wondering why Motorcraft and XOM have those two outliers with respect to gasoline ratings, though.

@DB_Cooper: That TBN might seem a bit low, particularly compared to what we're used to with HDEOs. It's actually not that out of line with a number of products out there, particularly some of the newer HDEOs. It seems that unless a newer HDEO meets an ACEA specification calling for a higher TBN, it's likely going to be in the 7 range. That's really not a problem, though, with ULSD. The guys pushing the OCIs in the diesels will likely be using an ACEA rated synthetic that will have a higher TBN.

Thanks Garak..Delo looks like very stout stuff. A UOA at 5k would be interesting on a 1.8 VW engine I built recently.

Delo ftw if you're using it in a classic gasser with high valve spring pressure.

Delvac ftw for longer oci in diesel.
