When diesel fuel inadvertently mixes with engine oil, it compromises the oil’s viscosity and lubricating properties, leading to potential engine damage if left unaddressed. This is particularly common in diesel engines during short trips or periods of low operating temperatures, where the fuel does not reach optimal combustion temperature.
Performing the Paper Towel Test for Diesel Oil Mix
Over time, this accelerates wear on critical components such as bearings and cylinder walls, making early detection vital for engine longevity. The presence of diesel reduces the oil’s flash point and thins its consistency, diminishing its ability to form a proper lubricating film.
The faster the oil spreads and the less defined the ring, the higher the level of fuel dilution. How the Paper Towel Test Works To perform the diesel in oil paper towel test , you will need a clean, white paper towel and a small sample of the engine oil in question.
How the Paper Towel Test Reveals Diesel Oil Contamination
Observing how the oils spread and interact on the absorbent surface reveals critical information about contamination levels. Complementary Diagnostic Methods Professional diagnostic tools offer more precise measurements of fuel dilution compared to the diesel in oil paper towel test.
