What causes fuel to get into oil?
The Fuel Mixture Is Too Rich: One of the main causes of why your gas is getting into the engine oil is because your fuel mixture is too rich. The combustion chamber won’t ignite all of the fuel and this will cause the gas to run through the piston rings and into the oil.
Should I add oil to my diesel fuel?
In most modern countries, no diesel fuel can be marketed without such additive. So, adding a 2T oil to increase the fuel’s lubricity is first of all, not necessary. The motor oil can clean this off for a while, but eventually it will become overloaded with soot as well and the soot deposits will cause engine wear.
What kind of engine does a Kenworth W900L have?
Drive a Kenworth W900L with C-15 w/ twin turbo, fired up one morning started missing at idle and through the gears. After changinging fuel filters with no result we put it in shop and found #1 and #2 injectors bad.
Can you tell if there is fuel in the oil?
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. Based on the report, I would then go after the oil dilution problem.
What to do if your diesel engine is getting into your oil?
Based on the report, I would then go after the oil dilution problem. Even if the engine has seen some excessive wear from the diluted oil in the past, that Cat engine will probably serve you well for many years with the low use you give it . . . that is, once you stop the diesel from getting into the oil.
What happens if you put diesel fuel in your crankcase?
Please keep in mind that diesel fuel in the crankcase drastically impacts the oil’s lubricity and creates excessive wear in all parts and the turbo bearing. 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.
