What are the differences between diesel engine oil and gasoline engine oil?
1 Answers
Here are the differences between diesel engine oil and gasoline engine oil: 1. Different API classifications. Diesel engine oil classifications start with "C", while gasoline engine oil classifications start with "S". 2. Different combustion flame temperatures. Diesel engine oil has a combustion flame temperature of 1800 degrees Celsius, whereas gasoline engine oil burns at 600 degrees Celsius. 3. Different oil viscosities. Diesel engines operate in harsher conditions, hence diesel engine oil has higher viscosity. Additional information: The functions of engine oil include reducing friction and high temperatures, minimizing gas leakage, preventing contamination from external sources, protecting against contact with water, air, acidic harmful gases and components, buffering pressure increases in engine cylinder ports, and cleaning dirt generated on component surfaces.
