Conventional Vs Synthetic: Which is Better?

The most common conflict while choosing an ideal engine oil is “Conventional Vs. Synthetic Engine Oil’. There are so many features that are equally significant as oil viscosity. But how to know them? Which engine oil is more beneficial? What is the basic difference between the conventional and synthetic? Which oil is worth my money?

What is the Difference Between Conventional and Synthetic Engine Oil?

The best way to understand things is to differentiate them from each other. And the basic reason behind the difference between two things is their divergent origins.

Conventional engine oil is basically derived from the distillation of crude oil. Crude oil is the ultimate formation of dead remains of marine animals and plants that existed millions of years ago. This fossil fuel was made when the dead animals and plants submerged in the oceans and decomposed in the presence of sand and silt.

Synthetic engine oil is not obtained through the distillation process, it is synthesized chemically. The basic components of the natural crude oil are taken out through chemical reaction. Then the disassembled compound, that can also be called ethylene, is processed to make synthetic engine oil.

Conventional vs Synthetic Engine Oil – Pros and Cons

Here we will briefly discuss the pros and cons of both conventional and synthetic engine oil:

Conventional vs Synthetic Engine Oil - Pros and Cons

Conventional Oil


Conventional engine oil is comparatively easier to produce therefore it is easy to access. The other advantage of conventional oil is its less expensive. Besides being easily available at less price, it lubricates the engine well and reduces the friction in the engine and overall performance of the vehicle is improved.


Conventional oil is comparatively less refined than the synthetic oil which makes it less effective and  efficient for extreme conditions and heavy vehicles. It needs to be changed more frequently than the synthetic oil for its varying molecular change that ultimately causes engine sludge and damages the engine internally over time.

Synthetic Oil


There are various benefits of choosing synthetic oil for your engine. Synthetic engine oil has a high temperature resistance and the clean quality ultimately lowers the need for consumption. Synthetic oil is effective on the problems that are faced by conventional oil users. The consistent size of the molecules decrease the friction and keeps the engine clean which ultimately prolongs the life of the engine.


The major drawback of synthetic oil is its expensive price. It is costlier than conventional oil but the high price is reasonable for the quality it comes along. You can avoid bigger expenses on repairing the damage that can be caused by low quality oil.

Conventional Vs Synthetic: Which is Better?

Now coming to the conclusion, here’s the final verdict:

  • If we put both the oils together now, we will get to see that the major difference between the two comes from the level of refinement. Conventional oil is less refined than the synthetic oil and this basic difference ultimately leads to major differences in the performance quality of the engine.
  • Conventional oil is more likely to form sludge while the synthetic oil is a better lubricator and maintains the cleanliness of the engine with less deposits.
  • Synthetic oil needs to be changed less frequently than conventional oil and the less emission quality of the synthetic oil keeps the engine protected in extreme conditions as well.

End Note

Finally, It’s your call! You can patiently consider the benefits of both the oils and decide the best for your vehicle. You must also know your car better before choosing what suits it best. Just never hesitate to change for the better.
