Which in turn will increase the gas mileage infinitely.   The longer you keep the battery disconnected, the better overall fuel economy you will get.

Replying to: dasdal (Jun 02, 2009 12:47 pm) I think the theory is that if you reset the engine computer by disconnecting the battery, the car components will have to relearn your driving style. So if you take it real easy after the reset, the SUV will learn to sip fuel, go easy on the shifting, etc.   I don't think it works like that in the real world though. The computers may have to relearn, but they are always compensating depending on what signals the various sensors are sending them.   It's a cheap experiment to try (assuming that you don't lose a radio antitheft or other security code when you disconnect the battery and have to pay a dealer to reset it).

Replying to: steve_ (Jun 04, 2009 10:13 am) In my experience they start rich and then lean the fuel mix out as you go. So odds are the first tank will have even lower mileage than he's getting now.   Longer-term it may have small gains, but I bet checking the tire pressure more often works out just as well.

Replying to: ateixeira (Jun 04, 2009 10:19 am) I threw away a seat in my minivan when we first got it a decade ago. I bet that's saved me a nice hunk of gas over the years.   Yeah, check the tires, toss out the extra junk stashed in the back of the SUV, anticipate the red lights. That simple stuff goes a long way.
