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.
Why does my BMW burn so much oil?
Burning oil is usually caused by leaking oil that burns up on hot engine or exhaust components. Oil is used by your engine to keep the parts lubricated and working well. Overtime some of the seals or gaskets may begin to leak due to wear and tear or exposure to heat.
What causes excessive engine oil consumption?
Because of wear, vehicles are more likely to consume engine oil as they age. Common culprits that result in burning oil include worn valve stems, guides and seals, and piston rings, all of which can allow oil to seep into combustion chambers.
