valvoline durablend Vs durablend diesel?

[dmarsc10]

Ok so ive searched for a fair bit and can't find the answer to my question. In practical terms, what is the difference between "durablend" and "durablend diesel"? The valvoline website recomends either for the zd30 engine, however only the "durablend" is available from my local supercheap shop. Will this oil be ok (10w-40 version) for my 2006 d22 Navara? Or should I stick with a diesel specific type oil? "Durablend" is rated ACEA A3/B4-04 and says its ok to use for both petrol and diesel applications...... so why then do they also make a diesel specific version of this oil.
Thanks in advance for any info.
