Valvoline "blue" oil

[coxfmly]

Has anyone used the new diesel oil by valvoline?
If I'm not mistaken it is blue in color. I dont think it's synthetic either.
Thanks

Have not seen or tried. Does your GM with Banks have a blow by issue. On my new rebuild of 6.2 with Banks the turbo seems to suck oil from new CDR.

Is it a CH-4, 15-40W?

No issues with blow by and it is 15w-40
