- Air and gasoline combined and are forced into the cylinder
- This mixture is then compressed.
- The spark plug then fires, igniting the mixture causing it to explode, this forces the piston up which gives the engine its energy.
- The burned emissions are blown out as exhaust.
A diesel engine has a higher compression rate and doesn’t use spark plugs. Diesel engines have such a high compression rate; the heat produced by the compression ignites the fuel and air mixture. The typical stroke cycle for a diesel engine is:
- Air gets forced into the cylinder, and is compressed.
- At the same time, diesel fuel sprays into the cylinder.
- The compression ignites the diesel fuel, causing the piston to move up, giving the needed energy burst.
- Again, the burned emissions are blown out as exhaust.
Diesel tends to get better fuel mileage than gasoline, because of it being more dense, resulting in more energy per cycle. Gasoline on the other hand burns much cleaner.
So, there you have it, the differences between gasoline and diesel.
Where to buy Diesel Fuel?
Ok, so I successfully beat the dead horse regarding the importance of proper spelling when you are looking for something (or someone). So now you are well aware that diesel is spelled not like it sounds. You also understand why you must make certain that you use the proper kind of fuel in your engine. You even now have the strong understanding about diesel fuel.
After all that you are out and about, when suddenly you realize, “crap I need fuel”! Where can you go? Do you know your way around this area? Well that is ok you use your Smartphone, tablet, laptop, or other gadgets and do an internet search. Simple enough, right?
Actually, every gas station in America has at least one pump designated for diesel fuel. So finding a place that sells it isn’t the problem. The problem is that most ‘normal’ gas stations and convenience stores don’t cater to large commercial vehicles. Perhaps if you don’t have the trailer hooked up it won’t be an issue, but if you’re pulling any standard trailer, height will be.

This is happening because most gas stations are not designed to handle large trucks. The overhang may or may not be tall enough, but the actual drive lanes will not be wide enough. They are designed for cars and smaller commercial vehicles but not the standard trucking industry size.
For these, you will need to go to regular truck stops and larger fueling centers. Rarely will you find these in the heart of city, and almost never in the suburbs. No, you will need to go along the main thoroughfares and highways. Typically on the outer edges of major cities and all the open stretches of the American roadway.
The good news though, it isn’t like it was years ago. Now you can find service centers, truck stops, and such dotted all along the major’s interstates.
Fuel economy and efficiency are extremely important when figuring budgets and expenses. There are a few things you can do to aid in your overall consumption rate. Remember, almost 35% of the energy used is through the tires! Aerodynamics and speed are two other considerations, the use of roof fairings and trailer skirts add almost 10-20% in overall fuel savings. Idling for extended periods of time burns more fuel, as does rapid braking and accelerations. There are other factors that can aid in fuel savings as well, such as wheel alignments, tire pressure, and even the type of tire used.
If you care to learn more about this, the US Environmental Protection Agency (EPA) created the SmartWay Transport. It’s a program which collaborates between the freight industry and government. With the primary goal of reducing pollution and emissions, help improve fuel efficiency, and ultimately advance the trucking industry.
Diesel fuel is literally the lifeblood of the trucking industry. Have you purchased bad fuel? Ever ran out because your gauges malfunctioned or because you misjudged what you had versus the actual distance to a truck stop? Do you have a favorite truck stop? Share with us!
