By ton, gasoline is more expensive; by liter, diesel is more expensive. Here is some relevant information about diesel: 1. Concept: Diesel is a light petroleum product, a complex mixture of hydrocarbons (carbon atoms ranging from about 10 to 22), used as fuel for diesel engines. 2. Properties: Diesel has a boiling point range and viscosity between kerosene and lubricating oil, making it a liquid petroleum fraction. It is flammable, volatile, insoluble in water, but soluble in alcohol and other organic solvents. It is a complex mixture with boiling point ranges of 180°C to 370°C and 350°C to 410°C. 3. Uses: Diesel is mainly used as power for tractors, large vehicles, diesel locomotives, construction machinery, excavators, loaders, fishing boats, diesel generator sets, and agricultural machinery. It serves as fuel for diesel-powered vehicles, tractors, and other diesel engines.

I've been in long-distance freight hauling for nearly twenty years, and driving diesel vehicles is my daily routine, so I always keep an eye on fuel prices. The price difference between diesel and kerosene isn't significant, and which one is more expensive depends on the region and season. Generally speaking, kerosene is slightly more expensive because it's used for home heating and aviation fuel, so prices spike more sharply when demand is high. When I drove in Northeast China, kerosene prices soared in winter, often 10%-20% higher than diesel; in summer, they were about the same. Diesel prices are more stable and come with tax benefits. But ultimately, fuel prices follow international crude oil trends, and fluctuations are normal. I've compared prices at roadside gas stations myself—diesel is usually 0.1 to a few cents cheaper per liter. In the long run, driving a diesel vehicle is more cost-effective. However, if you use kerosene for home heating, it's worth shopping around to save money. My advice is to check real-time prices on an app before refueling to avoid getting ripped off.

As a homemaker relying solely on kerosene for winter heating, I often check fuel prices while grocery shopping. Diesel is usually slightly cheaper than kerosene, which is evident at local gas stations. Kerosene, used for heating appliances, has a higher tax rate and is seasonal—demand surges in harsh winters, driving prices up by over 20%. Diesel, being automotive fuel, experiences smaller price fluctuations, though both are influenced by crude oil prices. Comparing local supermarket data from last year, diesel averaged 20 to 50 cents cheaper per liter. Households using kerosene won’t save much, but choosing reputable stations avoids impurity issues. For tight budgets, I stock up on kerosene in summer when prices dip. A handy tip: watch for government subsidies to trim electricity costs. In short, diesel is more economical, but with different uses, it’s not a straightforward comparison.

From market observations, diesel and kerosene prices are quite close, with the more expensive one depending on current market conditions. Kerosene has high demand in the jet fuel industry, with slightly higher costs, often being 5%-10% more expensive than diesel. For example, the difference was more pronounced during this year's global supply shortages. However, regional differences exist: in North America, kerosene is relatively cheaper due to lower taxes, while in some Asian countries, diesel enjoys more subsidies. Prices are driven by crude oil fluctuations, geopolitical factors, and seasonal supply-demand dynamics. In the long run, oil price volatility is normal, and when choosing fuel, it's wiser to consider overall cost-effectiveness rather than just single price comparisons. The price gap between the two is not significant, so paying attention to local data can help save money.
