My understanding of the advantages of adding Diesel to the gas might be in error, but I've seen a definite power increase on numerous dyno runs with doctored fuel, and less of a tendency to spark knock on long uphill pulls on repeated road tests. One theory is that the Diesel slightly increases the specific gravity of the fuel, and slows down the burn rate slightly- - - -the same thing adding an octane booster does. I don't fully understand the physics behind it, but the improvement can be documented- - - -repeatedly! Since Diesel has slightly more BTU's per gallon, I've also seen a marginal improvement in gas mileage when running Diesel-boosted fuel.
