What is the cause for high oil consumption in diesel engine?
Any deposits of unburned fuel on the cylinder walls result in mixed friction. The consequences of this are high and rapid wear of pistons, piston rings and cylinder running services, and high oil consumption.
Is it normal for a diesel engine to consume oil?
Diesel engines consume more engine oil than petrol engines. For technical reasons, oil consumption is at its lowest after the engine’s running-in phase and increases over the life of the engine due to wear. Wear within the engine will affect all components equally.
What is the possible case of high oil consumption?
In some cases, excessive oil consumption can lead to shortened oil change intervals. Lubricating oil consumption can also affect the rate of formation of deposits in the engine.
Is it normal for diesel engines to use a lot of oil?
Each engine will have a natural and acceptable amount of oil consumption, which you do not need to worry about. Any consumption above these given levels is excess consumption and should be addressed. Below are some common reasons why diesel engines will consume oil.
What causes excessive fluid consumption in a diesel engine?
Using incorrect, old or dirty oil can cause an increase in fluid consumption. If you replace the original oil with a cheaper and less effective brand, it can influence the entire system. If you don’t stick to a maintenance schedule or the oil is contaminated, it won’t be able to lubricate the engine properly.
Can a low mileage engine use too much oil?
All engines will consume some amount of oil, and as an engine ages and wears we generally accept increases in consumption, but in low mileage or low hour engines oil consumption can be frustrating. Letting an engine with truly high oil consumption go unchecked can result in shortened engine life and/or engine failures.
Why are diesel engines not good for high mileage?
From all the engines I have worked on, I have found that they don’t do much for a high mileage diesel engine with tons of blow by and high oil consumption. The reason – high internal engine pressure – 2 to 3 times what is produced in a gasoline engine.
