The fluid is free for 4 years 50,000 miles. My car wasn't up on that board when I was there Tuesday. I don't think Paul was driving my car around. Mine had 8.1 miles on it and I told them not to let people drive it. The fluid only needs to be filled or flushed once a year, or every 11,000 miles. It puts out 20% less emissions than the gasoline motors. I coudln't smell anything when I smelled the exhaust.
