Diesel and Gasoline Engine Oil

There are various differences that make these oils are not interchangeable in some cases and the first reason is for their catalytic converter. We know that our vehicle has a porous metal filter along the exhaust line between the muffler and the engine which function is to convert toxic emissions into benign products. Some materials can change the performance especially zinc and lead or phosphorus that is typically higher in diesel engine oil, making it not suitable for gasoline engines because it can lean to converter malfunction.

Second reason is because diesel engines have more space in between the crankshaft and rod bearings which makes it not ideal when paired with thin oil for it will only drain from these wide spaces hence diesel engine oil is higher in viscosity. On the other hand, using thicker oil in gasoline engines will affect the temperature and produce higher heat while especially not good in low temperature conditions and startup. Another reason is their level of additives for diesel engines usually have more additives to prevent strain and engine wear.

This level of additives if used in gasoline engines will harm the deposit on the cylinder walls that helps seal the combustion gases and when this is damaged, it may affect the catalytic converter, making it fail to work or even cause the engine to smoke from the inside. Diesel engines can be used in gasoline when it is heavily modified in order to produce more horsepower or when a certain oil gains the certification to work on both diesel and gasoline engines stated by SN labeling.
