Just be aware that this is not a C grade oil, so probably won't be usable in most passenger diesel engines after 2005. Basically anything with a DPF.
This particular oil is basically for old Mercedes Sprinters and older Japanese medium trucks.
For example, my 2010 Hyundai i30 CRDi can't use it because it doesn't meet the ACEA C3 specification.
The letter (A3/C3/E3) are not quality grades, so neither A nor E is better than C, it's different.
If in doubt, check your manual for the accepted grades. The codes must match exactly (EG, your manual must say something like "ACEA E5" or "MB 228.3" or any of the others in the list on the link).
