Consuming fuel is a big concern for many of us, and not least for those who run a diesel truck engine. This beast can eat through fuel like nobody's business, and it can sometimes be a mystery to the driver where all the fuel they put into their engine went. If you are trying to monitor the fuel consumption of a diesel truck engine, perhaps because there seems to be a leak, or there are unexplained discrepancies in the total fuel used, then you may be considering a number of options which can help you to monitor the amount of fuel being placed into the engine.

Step 1- Use Technology

There are a number of ways in which technology can help you to answer your questions about fuel loss in a diesel truck engine. The simplest method is by tracking the miles covered and the fuel put in using a computer software program. This is a basic operating program that requires you to input the information as you obtain it, but you can also use machines in the system to deliver electronic results to your computer. Whichever method you use, the computer will provide a series of analysis of the results, so you can spot any discrepancies between the fuel being used and the amount of miles traveled. Modern technology also means that you can use a GPS tracker to follow the miles logged on the truck. This will all give you a clear idea of monitoring the fuel consumption of one diesel truck engine, or perhaps several.

Step 2 - Use the Old-Fashioned Method

A more old fashioned method of monitoring the fuel consumption of a vehicle is by adding a dye to some fuel in the engine, and then running the truck on a service garage runway until the dye ceases to emerge from the exhaust. If you know the amount of fuel contained within the tank, then you can work out how long it took the truck to burn through a certain amount of fuel, you can calculate this in miles, or in time spent before the exhaust ran clearly. This method has been used by garages for many years to work out if there is a problem in the fuel lines of cars, and so you can use it effectively to tell how much your truck engine does to the mile.

Step 3 - Use a Pencil and Paper

Another old fashioned method is to calculate the amount of fuel put into an engine, and work out how long the engine takes before it needs a refill. This can be done without the cost of using a garage, and this is something that you can do on a regular basis, as long as you have a calculator. This is an accurate way of measuring whether your engine is burning fuel consistently.
