I completed the LPG conversion of my car in October 1990; the first edition of this book was done April 1991. At that time, I had limited experience with the car on LPG, especially, no long trips. Since then, I've taken a number of reasonably long road trips, which is what I built this car for originally, but of course they were also real-life tests for my LPG car. Briefly -- everything was better than expected. The car ran great at all altitudes (sealevel to 9900 feet), in hot (104\degree) and cold (35\degree) weather. Fuel availability was good in most areas during daylight hours, poor at night, and in a few places hard to get. At no time did I run out of fuel however. The trip I'll describe was a 5,000 mile loop through the South West; 5,000 miles throughout California, Arizona, New Mexico, and Colorado, made in June--July 1991. About 1,000 miles were on the interstates, the rest on secondary or state highways. {\bf June 19:}
