That made for some good reading (just the article not all of your post
). I love this idea. Depending on cost this would be something to do. Ive also seen a group of people that use an oil that cost half the price of gas. This was also when gas was at $1.35. The conversion was on diesal vehicles only. Not only did they double the mpg but it had an increase in horse power. All at a cost of $2000. I dont have the details of this as it was a Discovery special on alternative fuels.
