What is the maximum lubrication oil temperature that should not exceed?

The maximum lubrication oil temperature that should not exceed is 250°F (121°C). This temperature is crucial for maintaining the integrity and performance of the lubrication oil in diesel engines. Exceeding this limit can lead to oil breakdown, reduced lubrication efficiency, and increased wear on engine components. High temperatures can cause the oil to oxidize more quickly, leading to the formation of sludge and deposits that can clog oil passages and negatively impact engine performance.

Operating within this temperature range helps ensure that the oil retains its viscosity and protective qualities, which are essential for minimizing friction and wear between moving parts. A consistent operational temperature below this threshold is vital for the longevity of both the oil and the engine, promoting efficient performance and reducing the risk of damage.
