What happens if you mix engine oil with diesel?
If you put diesel into the engine oil you’re headed for early bearing failure. If you’ve put engine oil into the diesel fuel tank all is perfectly OK. The diesel engine will work perfectly well with lubricating oil. Mineral is much better than synthetic in this regard.
What causes diesel fuel to mix with engine oil?
* piston ring blow by fluids from too full a crankcase or broken piston rings. To have diesel fuel, get mixed with the engine oil, you would need to have a hole in the piston, so that out of every 4 strokes, in a 4 cylinder engine, the one cylinder has the diesel fuel sprayed at the piston head, but it does not ignite.
What happens if Diesel gets into the lubrication system?
Contamination of the oil must be remedied immediately as it will cause damage to the engine. There are three possible routes for fuel to enter the lubrication system Fuel lift pump – The diaphragm can split providing a route for diesel to enter the engine crank case. Injector pump – Injector pump shaft seals have been known to fail.
Can a diesel engine be contaminated with water?
There can be one of two contaminants in the oil; either coolant water or diesel fuel can escape from their systems. The first observation to make is to assess the colour and consistency of the fluid. White creamy coloured oil is indicative of water contamination, where as diesel contamination tends to dilute the oil making it less viscous.
Is it OK to mix motor oil with synthetic oil?
There can be different additive chemistry at play, so adding conventional motor oil to synthetic oil (and vice versa) is fine for a top-up. As AMSOIL’s literature suggests for their synthetic oils, adding regular oil to their long-life synthetics will shorten their lifespan. Can You Mix Diesel Engine Oil And Gasoline Engine Oil?

How can I tell if diesel fuel is getting into my engine?
I would take an oil sample with the contaminated oil and send it to a lab. They will tell you what you already know, that there is fuel in the oil. But what you need to determine is if there are any high levels of any engine bearing material in the oil. That will allow you to judge if there is any real damage that has occurred to the engine.
