Synthetic Oil v/s Conventional Oil

Synthetic Oil v/s Conventional Oil: When it comes to maintaining your car, perhaps the most frequent thing we need to do is wash the car and change motor oil. Of course, less often, we also need to change the following things such as engine air filter, engine coolant, transmission fluid, brake pads, brake fluid, and tires, to name a few.


Most older vehicles, as the age-old rule-of-thumb suggests, had their oil change every 3,000 miles or three months, whichever came first. Modern vehicles may be required, depending on usage, up to 10,000 miles between oil changes, thanks to modern engine manufacturing processes, as well as modern lubricant technology. The question is, your motor oil doing all it should or all it could?

Conventional v/s Synthetic Oil: The Differences

When next time you go in for an oil change, your technician might ask “conventional oil or synthetic oil?”, at which point you may wonder that aside from the difference in how conventional motor oil and synthetic oil create, what difference do these oils make in my engine?

Synthetic oil typically costs 4 times as much as conventional oil, is there any benefit to making this oil change? Going back to the way that conventional motor oil and synthetic oil give us the key to why many automakers are switching their directions to synthetic oil, and why you should consider it most.

Conventional motor oil is refined and filtered from natural hydrocarbons found in the ground. Naturally, it contains impurities, such as sulfur and paraffin wax, which contribute nothing to motor oil’s natural lubricant qualities. These impurities make motor oil more susceptible to oxidation and can leave deposits in the engine. It reducing engine performance and possibly leading to engine failure if not strictly following manufacturer oil change interval recommendations.

Why is Synthetic Oil Best?

As for cost, why pay 2 to 4 times more for synthetic oil at your next oil change. Actually, here are a number of reasons:

Synthetic engine oil:

  1. Costs more, but lasts two to three times longer between oil changes, so costs balance out over time.
  2. Does not leave deposits in the engine, dissolves deposits left from conventional motor oil, extending the life of the engine.
  3. Maintain its lubricant qualities, extreme temperatures, from -60 °F to over 400 °F, protecting the engine in all conditions.
  4. Maintains its lubricant qualities even at lighter weights, which makes for more power output and better fuel economy.
  5. Better for the environment, as it does not rely on petroleum extraction, which has its own very special problems.

Benefits of Synthetic Oil

Testing done on cars which designed for conventional motor oil has also proven that synthetic oil is better. No matter if considering high-efficiency hybrid vehicles or high-performance race cars.
