Synthetic Oil Vs. Conventional What Should You Use?


Oil Has Three Main Jobs:

  • Cooling your engine
  • Providing lubrication
  • Cleaning contaminants

If you’re looking for an oil that will do all of the above better the choice is obvious. Choose a full synthetic oil.

If you’d like to learn why and how a synthetic oil performs better and if it’s worth the price. You’ll find the answers down below.

Why Synthetic Oil Is Better

Synthetic oil isn’t manufactured like regular oil. It is made up of artificial compounds to produce a superior oil that you can’t find in nature. It’s specifically designed for engines. 

Which means anything a regular oil can do a synthetic oil can do better.

How much better?

A lot better.

Here in Calgary where the temperature can drop to -29 Degrees Celsius during the winter a good quality oil is essential. This is where synthetic oil really shines. Synthetic oil can flow a lot better even in colder temperatures where a regular conventional oil would become super thick adding a lot of stress on your engine.

Another benefit for synthetic oils is their longevity.

Conventional oil is almost useless and has very little life remaining at the end of its 5,000km interval.

Compared to a synthetic oil which will still provide protection for your engine, right up to the point when it needs to be replaced. The video below by popular YouTuber Engineering Explained demonstrates these points perfectly.

What Oil Should You Use?

For some vehicles, synthetic oil is a must. Not using the recommended oil in your vehicle can lead to costly repairs. In that case, the choice is obvious.

However, if your car doesn’t specify which oil to use the choice is yours.

The benefits of using synthetic oil summarized:

  • The cost is close to the same in the long run
  • Synthetic oil provides better protection especially here in Calgary
  • More environmentally friendly as you’ll be dumping less oil

If you’ve decided you’d like to switch to synthetic oil there isn’t any setup or extra step you have to take. Simply switch the oil you use on your next oil change.

However, there is one drawback to switching to a synthetic. If you are already experiencing a leak switching to a synthetic will cause the leak to grow bigger.


Not because the leak becomes worse but because synthetic oil is able to flow a lot easier as mentioned above.

This will only happen when a leak already exists. If you’re experiencing a leak and thinking about switching it would be best if you fix the leak beforehand.

For most cases, if you’ve been using conventional oil throughout the entire cars life and it’s over 5-10 years old it’s best to stick with what you’ve been using instead of causing a new problem.


First, see what your vehicle recommends, you can use a site like Amsoil to see the correct specifications.

Next, choose an oil that will best fit your needs. If you’re living in an area that experiences low temperatures such as Calgary, and you value longevity and extra protection then a synthetic based oil would be best for you.

At the end of the day no matter what choice you make the only thing that matters is your engine has clean fresh oil.
