What oil does a bulldozer use? Comprehensive analysis of fuel and lubricant selection guide

Bulldozers are the core equipment of heavy construction machinery, and the choice of fuel and lubricants directly affects the performance and service life of the equipment. This article will combine the popular construction machinery topics on the Internet in the past 10 days to provide you with a detailed analysis of bulldozer oil standards and provide structured data reference.

1. Recent hot topics in the construction machinery industry

According to the data analysis of the entire network, the topics that have received the most attention in the field of construction machinery in the past 10 days include: the development of new energy construction machinery, optimization of equipment maintenance costs, and the impact of the implementation of National IV emission standards. Among them, the search volume of the topic "Heavy Machinery Oil Specifications" increased by 35% month-on-month, reflecting users' urgent need for professional oil knowledge.

2. Bulldozer fuel selection standards

Bulldozer diesel engines have strict requirements for fuel. Different grades of diesel should be selected under different ambient temperatures:

3. Bulldozer lubricant selection guide

Each system of a bulldozer has different requirements for lubricating oil, which are mainly divided into three categories: engine oil, hydraulic oil and gear oil:

4. Things to note when choosing oil products

1.Certification standards:You must choose oil products certified by API (American Petroleum Institute) or ACEA (European Automobile Manufacturers Association). The latest National IV emission equipment requires the use of engine oil above CJ-4 level.

2.Brand selection:It is recommended to use well-known brand oils such as Shell, Mobil, and Great Wall to avoid engine wear caused by the use of inferior oil. Recent market research shows that these brands of oil products can reduce the mechanical failure rate by 15%.

3.Mixing taboos:It is prohibited to mix lubricants of different brands and grades. If you need to change brands, the lubrication system should be thoroughly cleaned.

5. Recommendations for using oil under special working conditions

For special working conditions such as high temperature, high humidity, and dust, special oil use strategies need to be adjusted:

6. Common misunderstandings in the use of oil products

1."Higher viscosity is better" misunderstanding:The higher the viscosity, the better. It must be selected according to the recommended value in the equipment manual. Too high viscosity will cause difficulty in starting and increase fuel consumption.

2."Color determines quality" misunderstanding:The color of lubricating oil has no direct relationship with the quality. Some high-quality synthetic oils are transparent or light-colored.

3."The more additives, the better" misunderstanding:Excessive additives may destroy the chemical balance of the oil, so you should choose a regular product with a balanced formula.

7. Oil storage and management suggestions

1. The shelf life of unopened oil products is generally 3-5 years. It is recommended to use it within 6 months after opening.

2. The storage temperature should be kept between 0-35℃ and avoid direct sunlight.

3. Different oil products must be stored in categories and clearly marked.

4. According to recent industry reports, standardized oil management can extend equipment life by up to 20%.

From the above analysis, it can be seen that the selection of oil for bulldozers requires comprehensive consideration of multiple factors such as equipment model, working environment and oil characteristics. It is recommended that users establish complete oil usage files and conduct regular oil testing to ensure that the equipment is always in optimal working condition.
