If there is an abundant release of bluish exhaust gases, as well as the need to add engine oil, it should be concluded that:
AThe oil used is not very fluid;
BIf it is a turbo-diesel engine, it is perfectly normal;
CThe piston rings or cylinder walls are significantly worn.Correct
Explanation
The release of bluish smoke from the exhaust, accompanied by excessive engine oil consumption, is a clear sign that the lubricating oil is entering the combustion chamber and being burned. This is generally due to significant wear of the piston rings or cylinder walls, which lose their sealing capacity. If the oil were not very fluid, it would not necessarily cause this symptom of abundant burning. Furthermore, this situation is never normal, even in a turbo-diesel engine, as it indicates a mechanical anomaly that requires repair.
