Can diesel engine oil be used instead of gasoline engine oil

Engine lubricants have gasoline engine oil and diesel engine oil. Gasoline and diesel engines, although the same high temperature, high pressure, high speed and high load conditions, but the two still have a big difference: First, the compression ratio of diesel engines is more than two times the gasoline engine, its main parts are subject to high temperature, high pressure, the impact of the gasoline engine than a lot of big, and therefore some of the parts of the production of different materials. For example, the gasoline engine main shaft tile and connecting rod shaft tile can be made of softer materials, good corrosion resistance of the pasteurized alloy to produce, while the diesel engine shaft tile must be used to produce high-performance materials such as lead bronze or lead alloy, but these materials have poor corrosion resistance. For this reason, in the formulation of diesel engine oil to add more anti-corrosion agents, so that the use of the surface of the axial tile can generate a layer of protective film to reduce the corrosion of the axial tile, and improve its wear resistance. As the gasoline engine oil does not have such high corrosion resistance requirements, if it will be added to the diesel engine, the shaft tile in use will be easy to appear spots, pits, and even pieces of the adverse consequences of flaking, the oil will soon become dirty, and lead to the burning of the holding shaft accident. In addition, the sulfur content of diesel fuel than gasoline, this harmful substance in the combustion process will form sulfuric acid or sulfurous acid, along with high temperature and high pressure exhaust gases into the oil sump, accelerating the oxidation and deterioration of the oil, so in the diesel engine oil formulations need to add more antioxidant and make the oil is more alkaline additives. If there is acidic gas into, can play a certain role in the neutralization, do not cause the oil too quickly oxidized and deteriorated. Gasoline engine oil in this regard is not so strict requirements, if it is used in diesel engines, will be due to the corrosion of the acidic gases quickly deteriorate and fail. So don't use gasoline engine oil to fill into the diesel engine use! So, can diesel engine oil be used in place of gasoline engine oil? In the past for low-grade gasoline cars, some people have replaced this way, but the modern high-grade gasoline engine low-temperature sludge problem is more prominent, so add the proportion of dispersant than the diesel oil is larger than the proportion of diesel engine oil, which is ordinary diesel engine oil does not have. For both gasoline and diesel vehicles have a large mixed fleet and military fleet, in order to simplify the use of oil varieties, to avoid engine failure caused by the wrong oil, the use of general-purpose oil is the best choice. Universal engine oil lubricating properties to meet the performance requirements of gasoline engine oil and diesel engine oil at the same time, the formula between the components should be carefully selected and balanced, the selection of its components is much more complex. As the general oil additives than ordinary gasoline and diesel engine oil to be more, the price is also higher. But the general engine oil dosage is large, the oil change cycle than ordinary gasoline and diesel engine oil to be a little longer, the oil consumption is relatively low. Therefore, universal engine oil is economically reasonable, in Europe and the United States developed countries, universal engine oil has accounted for 80% of the internal combustion engine oil; China has a number of enterprises to produce high-quality universal engine oil, such as all the way line of anti-wear lubricants belong to the diesel engine oil.
