oil temp gauge for semi truck

What is the normal oil temperature of semi trucks:

Overheating of truck engine oil is not a good phenomenon, and the effect of overheating of engine oil on the engine is negative. First of all, if the temperature of the engine oil is too high, the viscosity of the engine oil will be reduced, and the lubricating and heat dissipation capabilities will be reduced. The temperature will also cause the oil to deteriorate, which can cause serious damage to the engine.

Furthermore, if the oil temperature is too high, generally the water temperature will also be high. Long-term operation may lead to failures such as cylinder scuffing. The above are the adverse effects that overheating engine oil may have on the engine.

What is the normal value of the engine oil temperature of the truck: The oil model used in Isuzu diesel engines is 0W-40. 0W-40 belongs to the oil viscosity grade standard. Standard, this standard is the viscosity level that the oil can reach at the standard temperature, which can be indirectly determined as suitable. The temperature used, 0W means that the oil can be used within minus 35 degrees, -40 means that it can be used within 40 degrees above zero use.

Motor vehicle engine oil temperature is normal:

The normal working temperature of general engine oil is 0-90 degrees Celsius, sometimes. It will be higher, but generally it will not exceed the water temperature, but the speed of the car will increase, and the temperature will also be higher, It reaches about 100°-110°, but if the temperature exceeds 120° for a long time, it is best to check. Temperature. The main reasons for the heightening are as follows: 1. The sealing performance of the piston cylinder liner assembly is poor, and the high-temperature gas in the cylinder escapes into the oil. The sump heats the oil. 2 There are too many scales on the cylinder block and cylinder head, the cooling system has poor heat dissipation, and the engine temperature rises. High causes excessive thermal load on the oil. 3. The fit clearance between the main journal, connecting rod journal and the bush is too small, and the lubricating strip If the parts are poor, the oil temperature will rise. 4. Because the oil level of the oil pan is too low, the oil pump is faulty, the oil passage is blocked or leaked. Due to reasons such as dew, the oil circulation flow is insufficient, so that the oil cannot be dissipated normally during work. 5. The oil level of the sump is too high, and the engine oil is heated by the violent stirring of the large end of the connecting rod. 6. The engine is overloaded or other reasons cause overheating, overheating the oil.
