What can cause the diesel fuel to mix with the engine oil?

The Causes of Fuel Dilution in Engine Oil This often happens in the region between the piston rings and the cylinder bore. Other factors include leaking of the fuel injectors, incomplete combustion of the fuel, low engine temperatures, long periods of idle time and frequent short-distance driving.

What happens if engine oil is mixed with diesel?

Can diesel get into engine oil?

Smallest amounts of diesel stick to the cylinder walls and enter the engine compartment through the piston movement. As a result, diesel enters the engine oil and increases the oil level. Likewise, the diesel entry in the engine can increase when often driving short distances.

What happens when oil and water mix?

So what happens when you try to mix oil and water? The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water.

What causes diesel to get into the oil?

When that seal leaks, diesel gets into the oil. Do you know anything about this problem?

But you, or the shop that will work on the engine, needs to discover “the smoking gun.”

What are the most common marine diesel engine problems?

This is the most common type used in recreational marine diesels. Typical problems happen when there is a blockage of the flow in the raw water side of the system. Perhaps there’s plastic debris, kelp or barnacles obstructing the raw water inlet outside the hull. Most often, the impeller in the raw water pump disintegrates.
