1.5 or 2 oz per gallon is what almost all herbicides are made to be mixed at (at least the ones i use). Mixing extra will not kill more shite, just increase chemical runnoff and waste money. Once you hit either 1.5 or 2oz per gallon (depending on chemical) it has reached its minimum ratio for maximum effectiveness. 2-4D only kills broadleaf plants, so it is safe to use on your yard. It wont hurt regular grass.

Eta: if it doesnt have a surfactant in it, adding some liquid soap will help it stick to oily plant leaves. Some concentrates come with a surfactant. It should say somewhere on the msds.
