I bought my first diesel in the summer of 2005, a 1984 Chevy Suburban. I ran bio-d in that purchased at the pumps in Fife, WA. After doing the research, I decided to go with a diesel conversion. I bought a 2001 Ford Excursion in January of '06 and had it converted in Logan, UT by www.goldenfuelsystems.com. I have driven over 16k miles and put more than 1000 gallons of WVO in my truck. The truck still needs to start/stop for the day on diesel and I use bio-d almost all of the time, except in winter when i cut it a bit. j-bennett@comcast.net
