I'm a new 2001 MC SS owner bought for better gas milage for my 75mi/day commute. I am also considering doing a CNG conversion - any advice or cautions?

im curious on what a cng conversion is?

 

Compressed Natural Gas. Its illegal to do it yourself but you can find certified installers to do it.

 

whats the diff between that and NA?

 

He means coverting it to LP Gas . (Like your gas grille uses.)

Instead of pump Gas.

 

Grills run on propane (LP). He's talking about natural gas like your furnance runs on. Your car would never run on pure natural gas, you'd have a separate tank. You'd start on pump gas to get it started and warmed up then switch to natural gas. Ford does that now with some of their trucks.

 

I have seen one or two '06+ Impalas in our location that have a couple stickers on them (claiming to be running on natural gas. Heck the fuel door has a sticker on it and if I recall says something about do not use or natural gas only. Don't quote me, been a little while.

BTW - I think these are fleet vehicles for a natural gas supplier lol! Go figure.

 

I have not heard of a Monte Carlo powered by natural gas, so this is a pretty cool original mod! Keep us posted!

 

That's what I meant Mike...lol
Thanks for the clarification!

 

Well, i guess no one here has done a conversion yet. From the research I've done so far the conversion won't do much up or down for performance. There is a fair amount of stations here in OKC that sell CNG at around $1.40/ gal equivalent. So the big savings is in the price of the fuel. The conversion does require a tank dedicated to the natural gas and the car will then run on either gasoline or CNG. You can even get a compressor installed and fill up at home if you have natural gas for heating and drive your fuel costs down even more. Conversions costs about $5-8K, adding compressor to house about $5K. Then there are some tax incentives to bring that cost down - and it varies where you live.
