Things like expensive Scanguages IIs didn't used to be necessary in order to fine-tune gas mileage.
A vacuum guage is all that used to be necessary to do this. Just watch it as you drive and maintain the least vacuum reading you could at all times by controlling your speed, the gear you were in, and how far down you were pressing the gas pedal. I mounted a vacuum gauge in our 1972 Dodge van camper way back when and it helped us regularly get 17-18 MPG on trips with it's 318 V8 engine.
Now days I guess you have to use gadgetry to do the same thing.
