That is not necessarily the case nowadays.
Diesel fuel was much cheaper because there were far fewer cars with diesel engines.
Since many more cars have diesel engines now the various governments increased the tax on diesel fuel to increase the revenue it receives. As did the fuel companies to to a far lesser extent.
Diesel fuel is almost always higher than gasoline. Reason being is the EPA regulations a few years back regulated that diesel be made much cleaner that it was in the past. It costs more to refine this clean diesel. Have you noticed that you do not see black smoke bellowing from diesel trucks anymore.
What else can I help you with?
Can diesel oil be used in a petrol engine or vice versa?
Because , petrol is ignited before or on reaching the dead center at low temparature. But diesel burns at high temp also that's why petrol is not sufficient to diesel engines.
Which one having high torque petrol or diesel engines?
Diesel engines have much more torque at low rpm.
What is the difference between Petrol Diesel Kerosene and LPG?
Carbon chain is longer as big for Kerosine and same time petrol has small as lighter carbon scale so the ignization point is relativley high for kerosin and relativley low for petrol an gasoline.
What to do when you put gas in a diesel motor?
Siphon it all out. Petrol (Gas) and diesel mix incredibly well so it is impossible to siphon off just the petrol, you need to remove the whole lot and then full it up with diesel.Depending on how old the car/truck is, it will respond differently to having petrol go through it. Newer direct injection/common rail/turbo diesels will not like having petrol run through them at all, and might mean replacing both the high and low pressure pumps(Diesel acts as a lubricant for these and when petrol is run through them it washes all the lube away) and the turbo etc. Older diesels might get away with running a bit of petrol through them, but again it is recommended removing all the petrol and just putting diesel in.Even putting a small amount of petrol in a diesel tank will dilute the lubricating power of diesel and may damage parts.In short, when you put petrol in a diesel, grab yourself some hose and siphon it all out!
Why petrol cannot be used in diesel engine?
Two main differences: The fuel intake system is different and the firing mechanism is different. First, Petrol engines fire using spark plugs instead of heat and compression, and they might not get the diesel fuel to ignite fully if the compression is too low. Second, Diesel fuel has different viscosity, different volatility, different cleanliness standards, and different air/fuel ratios, so the fuel injection system has to have different design features.
Should you buy a Citroen diesel if you do low miles?
If you do low miles, buying a Citroen diesel may not be the best choice. Diesel engines are generally more efficient on longer journeys, and frequent short trips can lead to issues like DPF (diesel particulate filter) clogging. Additionally, the higher initial cost of diesel vehicles and potential changes in regulations regarding diesel cars could make them less appealing for low-mileage drivers. Consider a petrol or hybrid option instead for better suitability.
What is the amount Difference between high sulfur and low sulfur diesel?
There is not a clear cutoff point between "high and Low sulfur diesel". Ultra low sulfur diesel ULSD is what is currently required for on road use. ULSD can contain no more than 15 ppm sulfur (15 micrograms sulfur per gram of fuel or 0.0015 wt.%). Low sulfur diesel would contain more sulfur than ULSD and high sulfur diesel more than low sulfur diesel.
Why used low sulfur diesel in military vehicle?
In NATO and most US aligned forces, they actually use JP-8, which is a kerosene derivative. As for why diesel would be preferable over unleaded gasoline/petrol, the reduced flammability of diesel, and advantage in low end torque produced by a diesel motor.
What property of petrol affects engine knock?
'Knocking' in petrol engines is caused by petrols low flashpoint - its high combustibility. The octane rating is too low for the compression.
Is 77000 miles high mileage for a 2002 diesel car?
NO. For a diesel this is very low mileage.
Why can't petrol be compressed and ignited as in the case of diesel engines?
petrol self ignition temperature is high and requires a spark plug instead to ignite.where as diesel ignites automatically under pressure because of low self ignition temperature without any spark plug....hence petrol cannot be used inplace of dieselWarning: The above answer is absolutely incorrect. Petrol's flash point is significantly below, not above, diesel. The heat needed for ignition in a diesel engine comes from a compression ratio of over 20:1. Petrol engines have compression ratios of less than 10:1. Even at this lower compression ratio, petrol will still sometimes flash over or "detonate," causing the engine to "knock." This kind of nonsense is why I stopped posting here.
What is High-low method of variable cost and fixed cost?
High and low method is the method for separating fixed cost and variable cost from mixed cost.
