Motor oil is an essential fluid in your car. Its purpose is to decrease friction and keep the engine of a car clean and free of corrosion. Another vital purpose is to shield heat from the engine's moving parts. Most car oils are made out of petroleum-based motor oils.


Petroleum-based oils degrade over time or break down due to the pressure and heat inside the engine. When this happens, the oil's chemical composition changes and it gets contaminated. After hundreds to thousands of miles, motor oils can't protect the engine so they must be replaced.


Synthetic oils are more tolerant to aging and heat. Their performance characteristics can be customized to go beyond the performance of motor oils and using them can potentially extend your engine's life.


What's a synthetic blend?


Standard petroleum-based oils and synthetic oils are totally compatible, and may be readily mixed. Certain motor oil manufacturers combine these two oil types and pack the mixture as synthetic blend oil. Synthetic blend motor oils provide several of the advantages of full synthetic motor oil for your car, but at a lower cost. Make sure to check with the car manufacturer or check your owner's manual before considering switching to synthetic blend motor oil. To get more ideas about motor oils, go to


The advantages of synthetic oils


Synthetic oil was made for high-temperature application in jet engines several decades ago once engineers found that petroleum-based oils easily break down and exhaust their lubricating qualities when exposed to extreme heat. With time, petroleum-based motor oils started to oxidize and form sludge, leaving harmful residue in the engine. Learn how can you mix synthetic and regular motor oil here! 


Developed in a lab, artificial synthetic oil lacks the naturally-occurring chemicals that decompose at high temperatures. In addition, it's made without most of the compositions that lead to oxidation of oil and buildup of sludge. Synthetic oil can withstand temperatures that'd otherwise burn petroleum-based oils.


Synthetic engine oil performs really well in heat, but offers lots of benefits in severe cold as well. Petroleum-based oil thickens during cold temperatures, which requires the battery and starter to work harder to run a cold engine. In contrast, low temperatures don't affect synthetic oil as much, and it'll flow more easily when starting the engine. As an extra advantage, the properties of cold temperature allow the oil to be pumped quickly throughout the engine, providing much better start-up protection from friction.



Custom-made synthetic motor oils have lots of additives. These help keep an engine's interior clean, and add extra engine protection for long periods.
