I'd say P&G won't, only way P&G is effective is if you cant get 70% or higher engine loading, with your automatic it will probalby down shift at 30-40% if anything close to my 2 GM's. Sentra SE-R did testing with his car with different engine loading using P&G.

With his car 70% load during the pulse, and engine off during coast is need to break even vs constant speed. I'm pretty sure that's impossible with a GM auto you can't get 50% load unless your REV's are way to high to be affective. And you probably won't be going engine off, 09-10 Cobalts auto's do allow flat towing so maybe your's does, but would be a lot of wear on the starter.
