Fuel Costs?

Question

I am aware of the raising fuel costs, but im more worried about the enviornment.

I am an absolute car enthusiast, but im questioning the use of convential gas vs Diesel, and the price of both.

Which one costs less overall, and is less harmful to the enviornment?

And what cars run off alternative fuels?

Answer 1

Diesel is more efficient, and you may be able to use biodiesel.  Right now it is more expensive though.

You can make almost any car run off CNG.  Do a google search for cng conversion.
