Neither technician a nor technician b is correct because The occurrence of blackened diesel oil is typical. Several hundred miles after an oil change is when this change is typically noticed.
Diesel engines run at compression ratios that are greater than those of gasoline engines. greater ratio compared to gasoline engines. increased thermal expansion as a result. more fuel energy that is transformed into usable power. In general, diesel oil is more viscous and pumpable at lower temperatures than gas engine oil. Several problems, including heat production, early wear & tear, and more, may arise if it were utilized in gas engines. Increased wear in the valve train, rings and liners, and other high-contact regions of the engine may result from adding natural gas engine oil to a diesel engine. Reduced soot control would result in higher oil viscosity. Compared to gas engine oil, diesel engine oil is more viscous and less pumpable at high temperatures. Several problems, including heat production, early wear & tear, and more, may arise if it were employed in gasoline engine.
