Dilution of motor oil in a gasoline engine (Mitsubishi Lancer 3)

If the cylinders are fed with a very rich mixture, if the engine is rarely or never forced to develop full power, or if the engine is often driven without warming up (city trips), then the consequence is incomplete combustion. Carbon deposits, oil charring products and other products, unburned fuel itself and moisture condensate lead to the formation of a suspension, acid) and asphalt. Unburned fuel hits the cold cylinder walls and flows into the boat, washing away the oil film from the cylinder walls and pistons. The consequence of this is insufficient lubrication of the working surface of the pistons and dilution of the oil, which affects the lubricating properties of the motor oil depending on the fuel content.

If the dilution is too high, it may be necessary to change the oil early. Since during hard driving (hot engine) the proportion of gasoline in the oil evaporates, it is necessary to check the oil level more often, especially in winter (frequent cold starts - increased proportion of gasoline in the oil).
