Which outcome is directly caused by a leaking fuel injector in a modern gasoline engine?

💡 Explanation

When a fuel injector leaks, excess fuel enters the cylinder and also bypasses the piston rings, leading to fuel dilution of the engine oil, reducing its viscosity because the fuel disrupts the oil's lubricant properties. Therefore decreased oil viscosity occurs, rather than engine knock, reduced NOx or improved emissions, which all require specific combustion-related mechanisms.
