    I
    186,000 go it as salvage and fixed it.. purchased when at 55,000
    So I've gone 130,000 and just changed the oil/tires.. finally the
    battery computer croaked last month and with the tow bill to my house
    and the used computer it came to like 225.bucks..
    The battery computer that controls the charging is at the end of the
    battery tray. So it went till the battery was very low. Charged with
    a bench power supply. Off and running again..
    But I've never done anything with the plugs.. so was getting spooked
    about the plugs getting frozen. Got the cheap platium plugs at about
    $4 bucks.THE MILGAGE WENT UP FROM AVG of 43.9-43 to now
    with 120 miles on my aqua blue baby after the reset to 49.7-50 MPG!!
    I've never gotten more than 46ish and that was just one summer...
    The only special tool I need was a piece of 3/8 plasic tubing to
    restart the plugs in the holes as its like 6" deep!! Yes I used
    never sieze and torqued to the 13 foot lbs!!

    So all you prius drivers, get in line for the new production run of the scanner for GEN 1 cars... see my ad at :

    You have heard of the "ScanGauge II" I hope. It's well under $200 and from what I can tell does the same thing, and maybe more. Thanks to the fine folks here on PriusChat, it's been a tool, I'm never without. I keep one installed on both Prii.

    Nice mpg improvement. I plan to do my sparkplugs at at about 160k km's (100k miles), though I might go a bit longer if my mpg's are still good when that time comes.

    Ordered my plugs from Auto Parts Tomorrow | ACDelco, Bendix Brakes, Denso, Motorcraft and more ordered 8 because I have 3 pri, 54.00 free shipping but the final price was 33 dollars because of a website glitch, I thought maybe the site was not legit so I called the service number, they said they were going to fix the site today so I ordered 8 more and $33 CAME UP AGAIN! 54 is still a good price for denso plugs.

    Maybe it was the oil change after 130K miles... I'm sure that stuff was like tar after that long... ;)
