Hi June

There are so many tips to improve your mileage, so I suggest you start with the FAQ Pravus Prime put together here at http://www.greenhybrid.com/discuss/s...ead.php?t=6662.
In addition, you can check out an article I put together a year or so ago at http://www.cleanmpg.com/forums/showthread.php?t=350

If your not using the red controls where you are located now (its been cold), this means your very serious about improving your mileage. There are some very safe basic tips you can improve MPG with, and there are some advanced techniques you can use that many on this board consider down right dangerous. You will have to decide what you want to consider and by all means, don’t do anything you feel is dangerous.

I use a compromise of the techniques I developed or learned for safety and acceptable mileage. There is so much to take advantage of for increasing MPG, but you need the gauges to monitor what works immediately, not at the end of a tank. Many of us have the Scangauge 11 which plugs in under you dash. Scangauge is now making a $20.00 discount to GH members till the end of this month: See http://www.greenhybrid.com/discuss/s...ad.php?t=12594

Here is what it looks like in my vehicle


There is a lot to learn and you can take short cuts we have learned in the past 2 years with some research and further questions.
