What Is the Difference Between Synthetic Motor Oil and Conventional Motor Oil?

Many people wonder about the difference between these often-repeated phases that they may hear in different auto repair shops, that is synthetic oils versus conventional oils and their utility for your vehicle, specifically, when it comes to the overall cost to performance ratio between the two.

The point to be noted here is, both synthetic motor oils and conventional motor oils actually do begin their lives in the ground. Let us explore the differences between these two types of engine oils and see if the extra cost you’ll incur is really worth the higher price tag.


Conventional Motor Oil

This is a form of engine lubricant that is derived directly from different types of crude oil. As a general rule, it does offer really good engine life enhancing properties that allow it to provide high levels of lubrication, even at the high temperatures on which today’s high powered automobile engines operate. Furthermore, it is also able to maintain its overall stability over extended periods of time.

Incidentally, all types and brands of synthetic motor oils actually do begin their lives as some form of conventional oil. This conventional oil is subjected to further modifications and refinements so that its lubricating and protective properties are greatly enhanced.


Synthetic Motor Oil

Synthetic motor oils have many different purposes, but as a rule they are able to outperform most conventional motor oils in various aspects. Some of them are specifically designed to increase the overall performance and also the life of vehicles that are driven a lot, such as high mileage cars. Other synthetic motor oils, on the other hand, are specifically meant for very high performance engines. These days, there is a wide variety of synthetic oil based engine lubricants that actually have been infused with the innate ability to increase your vehicle’s fuel mileage average by using highly specialized and advanced lubricating agents.

Some of the advantages that synthetic oil has over conventional oils include the following:

Reduced Breakdown 

Synthetic oils, as a general rule, tend to be more resistant to breaking down, when the engine is used on a more or less regular basis. This means that they do not need to be changed at frequent intervals, like their conventional oil counterparts do.

Less deposits

The thing about conventional oils is that, as they break down under the stress of regular usage, they tend to leave deposits behind on various engine components, very much like cooking oil deposits in a frying pan. Synthetic oil does not stick to pistons, rods, bearings, and other parts, but on the contrary, they also have the ability to actually remove such deposits thereby ensuring that the life and performance of your engine is greatly enhanced.

In the light of the above, we can conclude that when we compare the two, syntactic motor oils are better for your engine than conventional motor oils.
