County Sheriff's Department:
"The department has been using the gas additive for approximately four years. Prior to using the product, we were experiencing great tune-up problems... scheduling them every 10,000 miles...now we tune up at 20,000 to 30,000 miles. It has also eliminated the common cause of water in the gas which required continual individual unit treatment."

Forklift Maintenance Manager:
"We ran a side-by-side comparison test on some lift trucks and determined that the use of GSL-4® would reduce the unfavorable emissions in the shop from gasoline-powered vehicles. Mufflers were plugging up to the point the trucks would not run...now have all gasoline treated...and have not had a plugged muffler since."

Construction Company:
"I have been using Energy Additive's products for my gasoline and diesel fuel for over one year...have noticed a significant increase in mileage on all my vehicles. It is very obvious that the program is saving me money in fuel-related down time costs."

Commercial Gardener:
"I have been using your gasoline additive for about three years. After the experience I have had with it, I won't run my equipment without being treated with GSL-4®. For example, my car was running rough...put in the additive and after a few miles, it smoothed out like it had been tuned up. It felt like the car had much more power and it quit spark-knocking. I used to drain all the fuel out of my equipment when I put it away fro the season. Now I leave the fuel in the tank because the GSL-4® keeps it from going bad. It also keeps the tanks from rusting."

Sportsman:
"I fish every year on a large lake in Canada. Each day I travel the same basic route around the lake. Without the additive, I would have to switch to the alternate fuel tank at least five miles before I got back to the lodge. With the GSL-4®, I have fuel left in the tank when I get back. The three motors I've had over the last few years have shown the same results. The marina recommended a sludge cleaner before winterizing. They told me to expect to see a lot of sludge, but it was so clean from the additive that none came out. These benefits, along with easier starting and better performance, are the reasons I will continue to use GSL-4® in all my gasoline engines."
