Is Maintenance Needed When Engine Oil is at 20%?
1 Answers
Engine oil at 20% is still acceptable and can be used normally. Here is some extended information: Engine Oil Lifespan: Engine oil lifespan refers to the usable life of the oil. When the oil lifespan reaches zero, it means the viscosity and performance of the oil begin to degrade, and it no longer functions effectively as engine oil—this does not mean there is no oil left. An oil lifespan of 20% indicates that the current performance of the oil is at 20% of its original (new oil) performance. Percentage Value of Engine Oil Lifespan: The percentage value of engine oil lifespan is estimated based on the oil change interval. Since mineral oil, semi-synthetic oil, and full synthetic oil have different change intervals, the same percentage value of oil lifespan implies different remaining usable time and mileage for each type.
