Personally I would not do it. The downside seems bigger than the upside.My diesel takes 15 quarts.
I wonder if throwing say 2 to 3 quarts of VRP in with a quality diesel spec oil (with a robust additive package), over the course of a few oil changes, would give the cleaning benefit over time without diluting what a diesel spec oil needs to accomplish?
