Can I use this in my 18 wheeler freightliner with a Cummins engine

Yes sir absolutely. You might want to find the bg245 quarts to help save a little monwy

does this product have to be added every time new fuel is added to the vehicle?

In short no. It does not have to be added at every fueling but rather depending on how your vehicle responds. Most that buy the cans(11oz) rather than the quarts(32oz) are using for a passenger vehicle rather than a work truck. A good indicator is simply watching your mpg's. Miles per gallon are a good indicator of how efficiently your vehicle is operating. If you start to notice a drop from what you used to get, its a good time to use the 245 to help clean the fuel system. Every 15k is somewhat of a guideline but if your using different stations and getting different quality fuel, you might find that adding a can sooner will benefit you. Every car/truck is operating under different conditions but you may consider adding a can with each oil change or every 6 months. Basically whatever you see giving you the best results for your vehicle.
