Therefore, one of the tips for getting better fuel economy in your diesel truck is to turn off your vehicle at stoplights if you're waiting for long periods of time. When you turn off your vehicle, you allow the car to cool down and adequately use the gas within it. Excessive warmup periods can quickly eat away at the diesel fuel.
How can fuel economy be improved?
To save fuel, start the engine and then drive the car normally to warm the engine to operating temperature more rapidly. Fuel economy peaks at around 50 mph on most cars, then drops off as speeds increase. Reducing highway speeds by 5 to 10 mph can increase fuel economy 7 to 14 percent. Use cruise control.
Which diesel additive is the best?
Diesel Extreme is the best additive in the game. This one adds seven points to diesel's cetane score (which again improves the fuel's combustion performance), and it cleans and lubricates injectors and other critical fuel system components. Diesel Extreme also helps remove excess water and contaminants from fuel.
How often should you use injector cleaner in a diesel?
You should do a deep cleaning of the diesel injector at least once a year or after every 30,000 miles. However, it depends on the age of your vehicle, your driving conditions, and the type of fuel you use. Your vehicle owner's manual may give you the recommended clean-up period for your fuel injector.

Does redex improve MPG?
Measured Fuel Consumption
Redex petrol treatments and system cleaners reduce harmful deposits that build up and reduce fuel economy. Use regularly to keep your fuel system clean and to improve the efficiency and MPG.
What will reduce fuel consumption?
Explanation: Harsh braking, frequent gear changes and harsh acceleration increase fuel consumption. An engine uses less fuel when travelling at a constant low speed. Easing off the accelerator and timing your approach at junctions, for example, can reduce the fuel consumption of your vehicle.
Do cold air intakes work on diesels?
Another benefit of installing a cold air intake on a diesel truck is improved gas mileage. If there's too little oxygen, it could result in increased fuel consumption. Cold air intakes are designed to provide the optimal air to fuel ratio, which can lead to horsepower gains and improved gas mileage.
Can a diesel engine run lean?
Diesels can run rich or lean despite having no throttle. The mixture is completely unrelated to the presence or absence of a throttle. In a modern direct injection diesel, the thing that enters the cylinder on the inlet stroke is air (sometimes mixed with EGR). That's why they call it a 'compression ignition' engine.
Can you tune a diesel engine?
Modern diesel engines have many computerised components, which allow a mechanic to easily adjust their settings. That's why so many people love diesel vehicles because they can match your personal requirements. Tuning is done through the diesel ECU (Electronic Control Unit) and is relatively fast and straightforward.

Can you use too much diesel injector cleaner?
It is possible to give a car too much of a good thing and add too much fuel injector cleaner. If this happens, you can risk damaging the lining of the fuel tank. Also, you may notice that there is lowered engine performance and fuel efficiency.
Is too much cetane bad?
One of the very few benefits of cetane is its ability to speed up the ignition process in the cylinder, aiding with cold-weather engine starting. If you increase the cetane number too high (55 and beyond), it can deteriorate the fuel and actually cause a reduction in overall engine performance.
