That is a hard question to answer.
Too many variable to be able to have your car to show the advertised up to 5 MPG increase (you need to change the dial to an economy setting).
Unless if you can constantly run your car for about 1/4 tank on the same condition, it would be a very hard question to answer.
Edit: correction on the advertised MPG increase.
