I have a 2004 Nissan Quest that I can't seem to get over 18-19 mph on. I really want better gas mileage. Please help. Thanks

You came to the right place. A couple of new guys have Dodge minivans and a lot of what they are doing will transfer to you. So poke around and read and ask questions when you have them.

diaperden I built a top grill block for my Grand Caravan. You can look it up in the Aero Mod section. Look up crxmpg.com and metrompg.com these sites have a lot of info that will help. Also hands down the best mod you can do is get a Scan Gauge 2 and alter your driving habits.

Thanks for the plug, :p

Welcome to the site, what's your commute like and what're your goals?

Welcome to GasSavers :)

Take a look at the Stickies in the General Discussion thread to get started. Those give you an idea of what works.

Driving style helps also -- the ScanGauge is a great tool for doing so, and it's pretty-much plug and play.

If you have any questions, feel free to ask -- enjoy!
