"Being that I'm not a mechanic or very good with tools I was able to install your system in about two weekends. Your design, and instructions were very simple and easy for me to understand. My truck runs so smooth and I feel no difference in power or performance. I calculated that I am getting somewhere between 16 - 18 miles to the gallon in my 2002 Ford F250 7.3 liter engine. Gathering oil is not hard for me for I can't stop talking about what I'm doing with my truck and your system. My only regret is that I wish I would have done this five years ago. Thanks, to all of the Golden Fuel Team for your hard work on providing an excellent system that not only works well but performs flawlessly. Sincerely, Howard"
