What Diesel Motor Oil Types Are Good for 12 Valve Cummins?
Vehicle performance, efficiency and fuel economy significantly rely on the oil type. Diesel motor oil is of 4 different types:
Full Synthetic: The most common type of motor oil is full synthetic oil or synthetic oil. Your vehicle will perform in tiptop condition due to this highly efficient oil regardless of the weather conditions.
It comes with a low viscosity rating, making it ideal for power-intense vehicles. The moving parts of an engine get protected from frequent wear and tear.
However, synthetic oil is expensive, which is the biggest disadvantage. You have to pay 30% extra bucks to buy synthetic oil compared to conventional diesel motor oil. But its performance outweighs the price.
Synthetic Blend Oil: Synthetic and mineral oil mixture is known as synthetic blend oil. This diesel motor oil is cheaper and goes roughly the same mileage of 15,000 miles as synthetic oil.
But the performance regarding temperature resistance and heat resistance is pretty low than synthetic oil.
Premium Conventional Oil: The prime responsibility of premium conventional oil is to prevent deposit buildup into the motor.
It consists of many additives that efficiently break down contamination and debris. At the same time, offering outstanding resistance to high temperatures. This oil type will be the ideal solution if your motor engine runs hot.
Higher Mileage Oil: From the name itself, you can understand that higher mileage oil is suitable for engines with high mileage on the meter.
Moreover, this diesel motor oil is suitable for those vehicles that suffer a lot from regular wear and tear and have more debris and contamination inside. This oil type requires additives and the right viscosity rating to extend the service life of those used motors.
