Conventional Oil Advantage And Disadvantage

Conventional Oil Advantage And Disadvantage : Conventional oil also known as regular oil or mineral holds several advantages and disadvantage for certain driving condition and vehicle type. Here are some advantages and disadvantages of using conventional oil.

Conventional Oil Advantage


Regular oil is more budget-friendly compared to synthetic oil. If you are on a tight budget or have an older vehicle with no specific requirement for synthetic oil. Using regular oil can help you save on maintenance costs.


Regular oil is compatible with most older engine and vehicles that were designed to use conventional oil. It has been the standard lubricant for decades, and many older vehicle may not benefit significantly from switching to synthetic oil.

3.Adequate Lubrication

For everyday driving in moderate climates and under normal condition, regular oil provides sufficient lubrication to keep the engine running smoothly. If you don’t push your vehicle to its limit or subject it to extreme condition, regular oil can still do the job effectively.

4.Short Oil Change Interval

While more frequent oil change can be seen as a disadvantage in terms of maintenance time and cost. Some driver prefer more frequent oil change because it gives them an opportunity to inspect the vehicle more regularly. Regular oil change can also help to remove accumulated sludge and contaminants more frequently.

5.Widely Available

Regular oil is readily available at most automotive stores and service station, making it convenient for driver to find and purchase.

6.Engine Break-In

Some manufacturers recommend using regular oil during the initial break-in period of a new engine. The slightly higher friction of regular oil during break-in can help seat the piston rings properly, contributing to better long-term engine performance.

7.Environmental Impact

While the production of regular oil involves refining crude oil, which is a non-renewable resource. The environmental impact is relatively lower compared to the energy-intensive production process of synthetic oil.

Conventional Oil Disadvantages

1.Limited Performance In Extreme Condition

Regular oil is not well-suited as synthetic oil to handle extreme temperature and high-stress driving condition. It can break down more quickly under intense heat, leading to reduce lubrication and potential engine wear.

2.Shorter Oil Change Interval

Regular oil typically requires more frequent oil change compared to synthetic oil. The shorter oil change interval can be inconvenient and result in higher maintenance cost over time.

3.More Frequent Engine Wear

Due to its composition and lower resistance to breakdown, regular oil may not provide the same level of protection against engine wear. Especially in high-performance engine or under heavy loads.

4.Reduced Fuel Efficiency

As regular oil ages and break down, it can create more friction within the engine. Which may lead to slightly reduced fuel efficiency compared to using synthetic oil.

5.Sludge And Deposits

Regular oil is more susceptible to forming sludge and deposit in the engine over time, which can negatively impact engine performance and longevity.

6.Cold Weather Performance

In very cold temperature regular oil can thicken and become less effective at flowing smoothly through the engine. This can result in slower engine startup and increased engine wear during the critical cold-start phase.

7.Inconsistent Quality

The refining process of regular oil may result in variations in the molecular structure and impurity content, leading to inconsistent oil quality from one batch to another.

8.Enviromental Impact

While regular oil is derived from crude oil which is a non-renewable resource. Its production process involves less energy-intensive method compared to synthetic oil. Nonetheless regular oil still contributes to the consumption of finite fossil fuels.

9.Less Suitable For Modern Engines

Many modern vehicle and high-performance engine are designed to work optimally with synthetic oil. Using regular oil in such engine may not provide the level of protection and performance they require.

10.Limited Options For Extended Oil Change Interval

Some newer vehicle and high-end model come with extended oil change interval, but these are typically based on the use of synthetic oil. Using regular oil may not be recommended for these extended drain intervals.


Always refer to your vehicle owner manual and consult with a qualified mechanic to make the best choice for your vehicle maintenance needs.
