Ok so I have been messing around with P&G with engine on the past week or so on my highway trips. Since I had a 65 mile round trip to take my son to therapy then back home to swimming why not see what numbers I could achieve using the technique. Well I'm surprised I almost made it to 50 mpg. I was pulsing to 70 then gliding to 50mph. I saw 49 for a little, but hills on the way back killed it. Some good stuff though. Think I'll stick with it.
