Why Should You Add Motor Oil to the N14 Cummins Engine?

Parts inside the vehicle’s engine move constantly, and without the lubricant, there will be a lot of friction, resulting in engine decay and engine shutdown in the worst-case scenario. Here, if you add motor oil to the engine, it will work as a lubricant and reduce the friction between the engine parts. Apart from working as a lubricant, it protects the N14 Cummins engine from PM.

Again, after some time, acid starts to build up inside the engine. But acid can damage the engine parts. Besides, when you keep running your engine in acidic conditions, its efficiency will start to decrease. But when you add motor oil to the engine, it will neutralize the acidic condition in the engine and protect the engine from corrosion. 

3 Things to Look for Before N14 Cummins Oil Change

You cannot add any off-brand motor oil to your engine. If you do so, instead of protecting the engine, it will damage it. Besides, it can even void the warranty of your vehicle. So, before adding engine oil to the vehicle’s engine, consider the following factors.

·  Oil Type

For the newer N14 Cummins engine, it is advised to use mineral engine oil until the engine breakeven period is over. As soon as the breakeven period is over, you must switch to synthetic engine oil. By adding synthetic oil after the engine breakeven period, you will get superior performance from the engine.

·  Recommended Engine Oil Type in the Car’s Manual

Finally, you will have to check the recommended engine oil type in the car’s manual. You should never add engine oil that is not mentioned or recommended in the car’s manual. Because if you add motor oil, which is not recommended by the car manufacturer company, your car’s warranty will get void.

·  Viscosity Grade

While buying the engine oil for your vehicle’s engine, you will have to consider the viscosity grade or the thickness of the oil. Because if you are in a warmer environment, you will have to use thicker engine oil. And if you are driving in winter, you should use thinner engine oil.

If you add thicker engine oil in winter, it will get coagulated, and because of this, the heat won’t be able to dissipate from the engine. Eventually, your engine will start to overheat leading to engine failure.
