Defining Diesel Engine Oil?

The diesel engine oil should not be mistaken for diesel fuel oil. The diesel engine oil is used to lubricate the diesel engine, while the fuel is used to power or run the engine. Although some diesel engine oils are formulated for use in diesel engines, some can be used in gasoline engines.

The procedure in picking the right oil must be based on the oil if it is compatible with your engine. The process will assure of an efficient and smooth running of your car in any weather condition, less your engine oil manufacturer told you so. The diesel engine oil resembles gasoline engine oil, they just have little differences.

The two oils (of diesel and gasoline) have base oils that are compounded with diverse additives to refine particular oil properties, and their difference lies in the amount of add-on that is utilized. While diesel engines suck in more carbon, gasoline engines absorb more tar and moisture.

Why it is better if you have a diesel engine car?

If we compare cars with gasoline engines and those that have diesel engines, which will you choose? Diesel engine cars are more expensive than common gasoline engine vehicles because the diesel fuel is cheaper. But having a diesel engine has more advantages compared to gasoline engines. Here are some of those:

    • The new breed of diesel engines are now quieter and require a minimum of maintenance.
    • In contrast to gasoline engines, diesel engines are stronger in rugged and sloping terrain.
    • Diesel allows for a more mileage than gasoline that’s why they are used in heavy equipment and transportation.
    • Diesel has a variety of applications. It can be used not just for cars or light trucks, but also for tractors, ships, power plants, and other heavy equipment.
    • Diesel does not need spark plugs, unlike gasoline engine. This is much safer especially for the drivers and machine operators.
    • Most military vehicles and armored personnel carriers (APCs) used diesel engine because they are not susceptible to flames.
    • Diesel is mostly cheaper than gasoline. It is also denser, meaning, it could make more mileage compared to gasoline.

How to choose the best diesel engine oil?

Here are some of the criteria in choosing the best diesel engine oil for your car:

  • Versatility

Not all diesel engine oil is created equal. Choose the oil that can easily adapt to various uses.

  • Suitability

Make sure that your choice of engine oil has the right formulation of additives. Also, be assured that the one you choose is compatible with your engine. To be precise, consult your the owner’s manual.

  • Cost

Although not all cheap engine oils have inferior quality, a high price is not also an assurance of superior products. Ask your budget if you can afford such brand, then analyze the engine oil’s performance if it could really deliver value for your money.

  • Efficiency

Better to see to it if your choice of diesel engine oil can help you attain better fuel economy.

  • Cleaning capacity

Choose the oil that will cleanse your engine without damaging vital parts. Having a clean engine is also prolonging the life of your engine.

  • Viscosity

Choose the best oil that can deliver lubrication power even under pressure. Check the viscosity grade of the engine oil of your choice as this will determine the starting temperature of the engine.

  • Protection to wear

Pick the lubricant oil that would not cause damage to the engine. Instead, it should provide ultimate wear protection to extend the life of your engine.
