Much quieter diesel engine

“I finally got to put the ULS Diesel Enhancer in my Toyota Land Cruiser. It has around 252,000 miles and yesterday when I first put it in the tank I did not notice any difference, but today when I started it I noticed that the motor was more quiet than it usually is at first start. And my friend who used it also in his diesel Land Cruiser found a big difference in power and also said his is also a much more quiet motor.”
