I need a synthetic SAE 40 single-grade package with zero viscosity index improvers. The application will have an EGR system, DOC, DPF, and run on ultra-low sulfur diesel (ULSD). 1.0% ash or lower is required. A decent dispersant/detergent package is required. Permanent shear loss is the concern. What is available off the shelf?
I found Amsoil offers an SAE 30 fully synthetic single-grade but no SAE 40 equivalent.
Royal Purple offers SYN V EMD, a fully synthetic SAE 40 single-grade, but it's for an EMD locomotive engine, which I'm not sure has the required soot dispersants and detergents because I'm not sure that engine runs EGR. It also has some additives special for silver-coated bearings, which the target engine does not have. I am unsure what side effects such additives would impose.
Can anyone identify a package with these desired characteristics?
I would rather not discuss the reasons I am uninterested in a package with VIIs.
