While I could not assume a 230 measurement is accurate I could kind of assume the different would be pretty close. But like I said I stopped putting money in the V6 once I decided I will be giving it to my daughter.
For me tracking mileage is easy. I drive 31 miles one way to work every day and I fill up once a week. If I get under 10 gallons I am doing good. Most weekends I drive my truck. I have noticed that the colder the day the worst my mileage. During the coldest part of winter I can drop down to 27 MPG average over a week. On the hottest days I can drop down to 28 but that is just the AC working.
