"What Amsoil has done for my bike: I have a '06 Suzuki Gsxr and since using Amsoil oil, I have seen and feel a big difference when shifting gears, when running in hot/cold weather. Even in the offseason, when trying to start it up when the season starts, it speak volumes that there's no engine seizing. I am extremely happy with my switch and would recommend it to any serious riders." -A Satisfied motorcycle owner and customer of Mountain Eagle Synthetics

"What Amsoil has done for my guns: I switched over to Amsoil’s Gun Cleaner and Lubricant. I have seen a difference in the way my guns shoot, and I do not have to clean them as often. Compared to when I was using a competitor’s products. I would highly recommend switching over to Amsoil. You will not be disappointed."

At the time I bought this truck, the company I am leased to bought a number of identical trucks for their fleet. All of these trucks operate in much the same way, including operating environment, type of haul, etc.
