Wentworth's complete fueling history
I can't believe these numbers. I want to say it's just the bladder, but if it is, my gas tank is getting smaller by a gallon a week. I did very conservatively adjust the Scangauge so that the numbers I see are likely just below the real mileage, but this seems like too much.
Then again, I did just implement some new pulsing and gliding the last week or so, and I've been getting mileage 5-10% better than usual as a result.
I also have been filling up at a BP pump, the gas that comes with BP's Invigorate additive. Supposedly more energy content to the fuel.
Maybe it's possible. Maybe it's not. In any case, I do hope the numbers are accurate, since I'm going for a record this coming tank (already at 65 mpg after a day of driving, including a short trip), and would love a precise record of it if all goes well.
