Synthetic vs. Mineral Diesel Engine Oil: Key Differences

Synthetic vs. Mineral Diesel Engine Oil: Key Differences

Oct 12th 2022

One of the most essential facets of a diesel engine is lubricating oils. These intentional, highly necessary fluids provide lubrication to the engine and reduce the tension and friction of the components. The goal is to reduce the metal-on-metal contact points with a thin film and expand the life cycle of parts by mitigating wear. Here, we examine the differences between synthetic and mineral engine oils to help you choose the right one.

Synthetic Oils Explained

Synthetic oils can provide performance enhancement and protection to the vehicles it serves. This type of engine oil is a chemically made fluid with additives and runs thinner than mineral oil. There are fewer impurities because of their chemical composition.

Many modern-made vehicles thrive on synthetic engine oil because it helps fight against oxidation, corrosion of components, and excessive wear. A few other benefits of synthetic engine oil include:

  • Superior flow rates at reduced temperatures
  • Consistent viscosity at increased temperatures
  • Less frequent change rates
  • Fewer deposit formations
  • The reduced wearing of vital parts
  • Optimal fuel economy rates
  • Superior protection for the engine

What Is Mineral Oil?

Mineral oil is commonly used for older vehicles. The oil moves at a much slower flow rate and can increase overall fuel economy and change how the vehicle performs. This oil comes from refined, crude petroleum, and in the derivation process, the wanted hydrocarbons and contaminants are stripped from the base.

Usually, with mineral engine oil, you will need to increase the frequency of change cycles. If your automotive manufacturer suggests mineral engine oil, it’s vital to follow these guidelines. The lubricity is still relatively high and sometimes provides more lubricity than synthetic oils.

The Key Differences and How To Choose

When selecting the right engine oil, you want to ensure you use the suggested option for your vehicle. This factor will take priority. Regarding the key differences, synthetic oil for diesel engines lends more performance options compared to mineral oil. It’s also essential to note that mineral oil may be best for older vehicles.
